You got lucky, because yours obviously did. 1 wire 10- Cutout Relay Diode such as I N5408 Light Switch or R. In order to control the output of the alternator, there is a regulator. Start your car. If not using a charge light, you will still need to need to wire in a 510 or 470 Ohm resistor for the exciter circuit to tell the alt to charge. In order to "excite" or "turn-on" the alternator, you need to take a keyed 12 positive wire, run it through a 47ohm resistor, and connect it to the "L" terminal on the regulator plug. Each kit comes with a mounting bracket, tightener bracket, correct size pulley, diode/exciter wire, and wiring instructions and wiring diagrams. The last couple years my alternator had no voltage at start-up, but if I revved the engine a few times the voltage came up to about 13. and a brown wire. The final wire goes to the positive (ouput) wire on the alternator. It is also recommended to use a warning light or wire resistor when installing ? failure to do so could damage the alternator. The fat B+ wire that goes to the battery or fuse box attaches to the threaded post in exactly the same way it did on the original alternator. This also happens when this wire is unplugged from the alternator. Lastly, you need to ground the other (lower) field post. The alternator has tested fine and the bulb has been swapped out with a know good bulb ,so, that leaves the wiring at the blue wire. Let’s talk about wiring. As demand increases, the regulator increases voltage to the field wire, which in turn, produces a larger current output from the stator. So what you need is a pullup resistor on the W/R wire. the alt has the stator, feild and a ground wire(its a good ground) along with the large black wire to the solonoid. 8L V6 30v (Canada) I replaced my alternator which the bearing has gone really bad all of a sudden on the highway on the road for Christmas (25dec). This is the wire that attaches to the back of the alternator with a nut. Damage to vehicle may occur if wires are cut beyond the. If you have questions, call our marine engine technicians. We have all alternators and parts in stock ready to ship immediately. The main contacts disconnect the battery while the auxiliary contacts disconnect the ignition coil and short the alternator output to ground. Ford 9N & 2N wiring parts. Also notice the sense wire connects to the starter solenoid and it is fused. Let’s talk about wiring. My car alternator runs at 16 to 16. Note: This drawing shows some parts found only in the GM column kits. It needs a small wire that goes to the light on the dash, and it needs a heavier wire that carries the current out of the alternator and to the rest of the car. I'm believing its the clocks at fault after stripping down and checking I'm getting the same voltages (as above) directly out of the clocks and the battery light is dim when compared to the others.

This is how the alternator gets current to your batteries, by sharing the same wire the starter motor uses. SA250 WIRING. The pictures below show a CS130 alternator vs. My question is: does the A term on VR (yellow wire) go to the REG terminal on Alternator? And does it need to have a lamp or resistor(? ohms) in the wire to the key-switch?. In the original system, a resistance wire (embedded in the main loom) soaked up the excess charge if no lights were on. the stator terminal is normally about half of the output voltage and is used by Ford to heat the choke on the. Brown is circuit 25, charge indicator. The maximum output of the alternator is not diminished (and the RPM at which maximum is reached is not changed either). An alternator is so named because it produces alternating electrical current. If the vehicle does not have an alternator warning light, connect to switched +12V through the supplied resistor. Microcontroller – How To Monitor An Alternator Exciter Wire With Mcu – Alternator Exciter Wiring Diagram. Put both new alternator and new battery. The alternator uses a field or "exciter" wire to send a very small amount of current from the ignition switch to "turn on the alternator" to help it begin charging as soon as the engine is started. 00 Add to cart; Alternator, pre-2003 PCM RA097006 $ 209. The pulley nut must be removed with an impact wrench. and connect the red wire to the output side of the alternator 10/32 stud, take the long wire and connect to the + side of the coil. If not, unplug the exciter wire and verify you have 12 vdc at the wire plug. Free ford alternator wiring diagram are available to download here. I traced the white exciter wire to behind the dash tonight but it only ever seems to get around 3 volts. The only wire that needs to be connected is the “L” wire, but it requires either a warning light bulb in the circuit or a resistor. Powermaster makes lots of different altenators. This wire provides the "exciter" current to the alternator field windings. If your alternator stops charging, starting with a fully charged battery, you will only get 3 to 10 starts before the battery will no longer crank. 5 10 watt non-inductive. Alternator positive post reads 13 when car is off. The alternator will then attempt to maintain 14. 3 volt ranges (engine running, lights and accessories off), that means the alternator is working as it should be. Therefore our 0. Why NGR Neutral Grounding Resistor are used. Main Alternator. The exciter wire is blacked out as it leaves the alternator plug, so that little bit of wire going into your flex loom isn't as noticeable. Ford 9N & 2N wiring parts. Use the Sure Power Connector Kit #144CD to install external sense wire. Attach a voltmeter plus to this terminal and a minus to a ground. I had the truck jumped started, but it was clear the battery either 1). But the alternator has no way of knowing this - because we hooked the voltage sensing wire right to the alternator output - it thinks everything is fine, it thinks system voltage is at 14. exciter field winding rectifier automatic voltage regulator voltage regulator (rheostat) current transformer change-over switch,ammeter ac. 92 s10 with 04 5. My problem is the resistor gets very hot to touch (Whether the engine's running or not). - If is over 12V (should be something like 14 volts) then the alternator is charging. Figure 3-1 The Painless Wire Harness Kit. I'm trying to figure out what this resistor is that the PO used to bridge the #1 and #2 terminals on my alternator. the L terminal should be the third pin, counting from the end with the large end. If you follow the paths you will see that power to the coil and alternator excitation are supplied voltage at a common splice. I dont know jack about electrical but from my research I'm thinking. In order to "excite" or "turn-on" the alternator, you need to take a keyed 12 positive wire, run it through a 47ohm resistor, and connect it to the "L" terminal on the regulator plug. Note that the exciter wire has to be on a switched circuit, exciting the alternator only when your engine, or key switch is on. 001 Ohm resisitor would require 1000 * 0. The last thing I have with the car is this pesky alternator wire. It should be at least 10 Guage Charge wire with a 100 amp alternator. If a rectifier opens, the voltage regulator will substantially increase the excitation to maintain the operating level. A wire size too small can allow the wire to overheat, melt the insulation and cause a fire or worse. Replace the 6V Coil with a 12V Coil. 2 for the 120/240 volt connection, it will be seen that the alternator stator, exciter stator, and diode assembly are the same. 0 single alterntor. It is intended to aid all of the common user in creating a suitable program. Not the battery. The same ACD wiring adapter for ’84/’85 conversions is the one most ’69-’82s will use. That is a good thing. The CS series on the other hand does need resistance" He listed a coulpe other models that needed resistance (I can't remember what they were), but he assured me the SI series was fine without. Tools Needed: 7/16”, 3/8”, & 1/4” nut drivers. Like the original. NGRs grounding system provides more benefits […]. The exciter field tap is the wire from the modular plug on the Delco alternator (marked #1). Charge wire to battery. You can also make this connection to the hot side of the coil if your coil has an. The second field wire is connected to the outside plug on the newer voltage regulator (two plugs, one is in the middle, one is on the outside). The alternator will sink current from 12V through the bulb in to the alternator when it is not turning and then when it is turning the field will be energised to 12V, so 12V on both sides of the bulb makes it go out. No running yet, just turn the key on after you put the wire in and see if the light appears. Fits AD style alternatorsWeather Pack style sealIn-line resistor that allows but does. If a rectifier opens, the voltage regulator will substantially increase the excitation to maintain the operating level. It is designed for easy installation, even if you have no electrical experience. It starts with low resistance near zero, and as it heats up and draws current, that resistance rises, so the lamp acts as a current limiter in the circuit as well. What is a Core Charge ? A "Core Charge" is similar to the deposit you might pay for a can or bottle of soda. The pilot exciter armature is mounted on the stationary part of the assembly. Sanded all my grounds 7. 2k-ohm resistors in parallel). Make sure you wire your Marine Alternator correctly. Disconnected blue/white wire, restarted car. alternator is a 55 amp from a 79 monte. Findings and Conclusions. I finally found the correct alternator plug ($50. This will cause the alternator to be self-energized by the trio, rather than powered by the battery. The resistor only allows voltage to flow in one direction to the alternator. See all 7 photos. Good options for where to pick up this power feed include the battery positive terminal, alternator B+ terminal, large terminal on the starter relay, large terminal on the starter. Insert the white alterna- tor plug and connect the two red wires with the eyelet end to the "BAT" connection of the alter- nator. terminal block is a clean way to do it. We recommend putting a 100 ohm, 2 watt or greater resistor (in-cluded with the harness) in parallel with the alternator light to energize. Brown is circuit 25, charge indicator. The fix is to add an inline resistor or an old style bulb (not LED) inline from the +12V source to the alternator exciter input. They are connected to the stator windings. We have all alternators and parts in stock ready to ship immediately. My problem is the resistor gets very hot to touch (Whether the engine's running or not). I don't have a wiring diagram handy at the moment. Revving the engine might get it charging. It's not giving 12 volts. • B is the alternator output wire that supplies current to the battery. Found partial short to ground on main power wire to fuse/relay block in engine compartment. why for the resistor?. It starts with low resistance near zero, and as it heats up and draws current, that resistance rises, so the lamp acts as a current limiter in the circuit as well. A few days ago I noticed my volt gauge on the dash reading VERY low. ) Look for 12 volts on the yellow/white wire that is the power feed to the regulator. Before a dedicated one-wire alternator was developed, enthusiasts would make a jumper wire to “excite” the charging properties of the alternator. All in the same general area in this case,sometimes its a little harder to find the diode;be-leave me its some where in the harness. Disconnect your voltage regulator. A relatively modern alternator only needs two wires to do its job. If you have a working gauge you can just apply 12 volt to the I terminal. CS-130D Alternator Pigtail Painless Wiring 30705 Incl. once off the start cycle that wire (#1) is no longer energized. This wire lets you shut down the alternator when the motor is turned off. Also available is an ammeter package (1965400). An inline 10 ohm [2 watt + ] resistor should be installed [in series] in that wire, [that resistor isn't required for the alternator to actually operate, but is put there to protect the diode trio inside the alternator from damage due to a power surge]. 8 Gauge or 6 Guage even better. Alternator Wiring Kit 555 -10510 100 Amps 8 gauge 150 Amps 6 gauge 200 Amps 4 gauge It is very important to use the correct wire size to connect the alternator to the battery. normally this resistor is build in the wiring of the cars. If you have a warning light in the dash then that bulb serves as the needed resistance and you should use the non-resistor adapter. The ballast resistor keeps the engine running by preventing the engine from receiving full amperage from the ignition once started. 0 single alterntor. • IG is the ignition input that turns on the alternator/regulator assembly. The other wire at the alt indicator light should go to your voltage regulator. 2 for the 120/240 volt connection, it will be seen that the alternator stator, exciter stator, and diode assembly are the same. Each part ought to be placed and linked to other parts in particular way. The resistor is in a parallel circuit, the light and resistor in parallel with each other and The field relay contacts in the regulator; for the alternator's field exicitation before the alternator's operation to ensure voltage buildup when the engine starts. Wiring Diagram comes with numerous easy to stick to Wiring Diagram Directions. The process of supplying battery voltage to "kick-start" or "prime" the alternator is known as "exciting" the alternator, and the wire that carries the current from the alternator warning lamp to the appropriate voltage regulator terminal is known as the "exciter" wire. We recommend putting a 100 ohm, 2 watt or greater resistor (in-cluded with the harness) in parallel with the alternator light to energize. Where does the exciter wire attach upstream of the alternator? Thanks, DJ: August 29, 2014. The warning light supplies an exciter voltage that tells the regulator to turn on. Also required is a large resistor for accessories like original 6-volt heater or radio - use FS-129 or FS-129R. Voltage at battery ~12V, at B+ on alternator the same. I have checked the bulb and the wiring up to the alternator (all working) but can't figure. Note 2: This added resistance wire (or resistor) is not necessary if using a "1-wire" alternator. 240-204SEN *NEW* Alternator for Delco 10SI 12V 63A Self Exciting One Wire $95. GM alternators require an exciter wire with a 12V switched source, otherwise they won't charge. We can deal with two wires. 3G alternator: Look for 12 volts at the stud on the back of the alternator where the 4 gauge power feed wire is bolted. Understanding the Alternator • Four wires connect the alternator to the rest of the charging system. Start your car. The exciter permanent magnet and armature starts the generation process and the output from exciter armature is rectified and sent to the pilot exciter field. The G terminal (Black wire) goes to ground. There are many different types of exciters, depending on the design and type of generator. Meanwhile - 12 feet away the power-hungry amplifiers are only getting 13. This entailed running a wire from the battery post on the alternator to the R terminal at the two-wire plug location. Included with the Omega kit is an easy-to-add 330 ohm resistor assembled to a short length of color-coded wiring and nicely sealed in heat shrink tubing. why for the resistor?. Ballast resistor is part # FS-1008. Most are near the main power from the battery. • B is the alternator output wire that supplies current to the battery. A wire size too small can allow the wire to overheat, melt the insulation and cause a fire or worse. If you have a working gauge you can just apply 12 volt to the I terminal. the I terminal of the solenoid is typically used for this on the motorcraft starter models. Second, regarding 6 volt ignition systems converted to 12 volts. I dont know jack about electrical but from my research I'm thinking. A fusible link is a short ~6" wire spliced into a main wire and has a rubber bump moulded onto it. Typical sizes for small resistors are 1/8 Watt, 1/4 Watt, 1/2 Watt, 1 Watt, and so on. Somewhere between the alternator and the ignition switch I need to install a resistor (10 ohm 10 watt), so that when the car is turned off juice doesn't flow backwards from the battery through the exiter to the ignition switch and then to the coil, which would keep the truck running even after I take the key out. This is the wire that attaches to the back of the alternator with a nut. I wired the alternator according to the manufacturer's spec (POS, NEG, EXC to key on power source). What is the resistor's value? 2) Does the Hitachi alternator require the idiot light as an "exciter" to make the alternator begin to charge? Thanks! Reply to | Quote Reply | Add. The main purpose of exciter in a generator() is to provide stationary rotating magnetic field. If you connect the meter leads to the battery terminals and the meter shows that it's in the 13. It provides full exciter power, regardless of the generator voltage. On most OEM installations this terminal is connected to a switched 12 volt accessory source through a dash-mounted pilot light. After changing the alternator and it still not working I traced the issue to the exciter wire. Has anyone simply put the exciter wire to a switched ignition source?. Found partial short to ground on main power wire to fuse/relay block in engine compartment. 59mm diameter) for example has a resistance of 0. Referring now to the three-wire system of FIG. They are available in various shapes and sizes. After 3 minutes 'Battery not charging, make a safe stop'. My guess is that you would like a fixed alternator voltage (and power) output, independent of the bicycle RPM. Once the alternator starts charging it can be used as a low current source. I know it is easy to break the exciter wire since it is difficult getting the alterator out but it dont look broke. One of the 2 blue exciter wires goes from the alt to the instrument cluster (as JimmyC wrote) and the other goes to terminal 12 in the diagnostics connector. The AC output of the pilot exciter armature is supplied to the generator control circuitry where it is rectified, regulated, and then sent to the exciter field windings. well some ones done something odd as it shouldnt be d+ ignition battery light is the exciter wire that and b+ large wire to starter/battery is all it should have unless you fit the w terminal to a rev counter ,but without nothing ,car and dash are fed by a brown wire to ignition switch where a white wire takes off all ignition feed and white /orange takes off auxillary feed. I was looking at the wire diagrams and it appears that the 'exciter' wire should have battery voltage when in run and start. If not using a charge light, you will still need to need to wire in a 510 or 470 Ohm resistor for the exciter circuit to tell the alt to charge. It is my understanding that the alternator needs current flowing into the L terminal to get going. Two wires isn’t intimidating at all. As for the dash, my brother had a mouse chew through a wire on his 986. The ballast resistor is a coil of nickel-chrome or nichrome wire. 140- 200 amp alternator I would choose 4-guage to 0. The last thing I have with the car is this pesky alternator wire. Just to test that out, ground the wire to the body of the alt and check the light. I'm trying to figure out what this resistor is that the PO used to bridge the #1 and #2 terminals on my alternator. In larger sized generator, energy for excitation is often taken from a separate auxiliary source or from a separately driven DC generator. I got extra parts from different cars when I bought it and Im not sure how this should be hooked up. I wired the alternator according to the manufacturer's spec (POS, NEG, EXC to key on power source). The other terminal is the exciter. step one: connect the tac wire from the ecu to the tac input of the instrument. AD style alternator plug-pigtail incorporates a Weather Pack style seal and an in-line resistor that allows, but does not require, a charge light in this exciter circuit. The resistor was calculated to work with a 24V source, a 12V output, and 300 milliamps of current. 2 Volts at this connection. With a resistance wire the alternator voltage (terminal #1). step 2: in the junction between the previous connection, wire 12v into it but it must be through a 1k resistor. The other terminal is the exciter. Take a jumper wire and connect the blk/wht wire in the plug to ground of the car. These instructions will likely be easy to grasp and use. It is usually attached to the ignition switch where the wire goes to the hot side of the coil.

The alternator doesn't need a 4 Ga wire on the X1/9. The diodes fail by either going open circuit or short circuit. Let me know if you have trouble finding the resistor wire, if that is the way you decide to go, and I'll see if I can find someone that has one of them. The kits that I offer use a new 63 amp Delco 10SI cloned alternator. Make sure you wire your Marine Alternator correctly. The 100 amp alternator has a ground wire running from the alternator case to the engine block/alternator bracketry. The wire is part of the signal conditioning and filtering portions of the circuit. Grease the Rear Bearing. Brown is circuit 25, charge indicator. The ballast resistor keeps the engine running by preventing the engine from receiving full amperage from the ignition once started. Important: The information contained in this bulletin is intended for use On most heavy trucks you will find one, two or three wires going to the. Tested fine. If the resistance increases in the resistor, or if the resistor allows voltage to flow in both directions, it takes longer to excite the alternator which causes a. We hear from a lot of swappers who have this problem, particularly when swapping to a carbureted system. Note it must be a bulb or an LED with a high power (5w) resistor inline. The main red wire on the alternator harness/plug has power both on and off. 0 single alterntor. (by mistake) Now on many small aircraft you actually switch on the alternator after starting the engine. That is a good thing. You can also make this connection to the hot side of the coil if your coil has an. Meanwhile - 12 feet away the power-hungry amplifiers are only getting 13. I am attempting to straighten out the hacked up wiring on my alternator which prevailing wisdom says is what probably took out my FICM. Use a coil with an internal resistor or install an ignition ballast resistor in the wire between the coil and the ignition switch. It starts with low resistance near zero, and as it heats up and draws current, that resistance rises, so the lamp acts as a current limiter in the circuit as well. There is a 500 ohm resistor in parallel with the warning light so that if the bulb burns out, the regulator still gets the exciter voltage. 001 Ohm resisitor would require 1000 * 0. Record this value. ) Therefore, when an ignition coil that does not have an internal resistor is installed on a Ferguson tractor, an external resistor must be added to the ignition circuit. Thus a Wipac alternator potentially overcharges its battery with lights off. Alternator Exciter Wiring Diagram - alternator exciter circuit diagram, alternator exciter wiring diagram, Every electrical arrangement is made up of various different pieces. The alternator needs an amount of current flowing through it to generate the excitation field. Ok, so i have a 1999 exec that was a stocky 6 (look in my other posts for the car info) I put an ls1 6 speed into it. Welders Schematics: In the lower right hand corner of every schematics is a diagram number. No codes, but they said my alternator was bearly putting out any volts. An inline 10 ohm [2 watt + ] resistor should be installed [in series] in that wire, [that resistor isn't required for the alternator to actually operate, but is put there to protect the diode trio inside the alternator from damage due to a power surge]. alternator and alternator exciter wire, coil, water temperature, and oil pressure. Record this value. You got lucky, because yours obviously did. Alternator Testing You should have a reading of approximately14. (Image/Jeff Smith). 81 FREE Shipping. My problem is the resistor gets very hot to touch (Whether the engine's running or not). Each part ought to be placed and linked to other parts in particular way. Put both new alternator and new battery. The pictures below show a CS130 alternator vs. The kits that I offer use a new 63 amp Delco 10SI cloned alternator. An alternator is an auto part that transmits power from the fuel system to the battery for operating vehicle accessories, such as the radio, headlights and air conditioning fans. The 100 amp alternator has a ground wire running from the alternator case to the engine block/alternator bracketry. Might work, but will probably. - If is over 12V (should be something like 14 volts) then the alternator is charging. The pilot exciter armature is mounted on the stationary part of the assembly. If good, remove the plug from the exciter wire and plug it directly to the alternator “L” terminal. If your alternator stops charging, starting with a fully charged battery, you will only get 3 to 10 starts before the battery will no longer crank. 59mm diameter) for example has a resistance of 0. The reg controls the voltage to the exciter coils. Been looking at the websites for alternator, can't really come to a conclusion on the "need" for the light and resistor. You got lucky, because yours obviously did. 0L Ford pick up (SUV, or mini-van), this wire has an inline fusible link or a mega fuse, that protects the alternator in case of an electrical short. In the original system, a resistance wire (embedded in the main loom) soaked up the excess charge if no lights were on. As demand increases, the regulator increases voltage to the field wire, which in turn, produces a larger current output from the stator. They are available in various shapes and sizes. That is partly how an alternator can guarantee a current output at engine idle and low rpms. I'm believing its the clocks at fault after stripping down and checking I'm getting the same voltages (as above) directly out of the clocks and the battery light is dim when compared to the others. Thus a Wipac alternator potentially overcharges its battery with lights off. btw as Randal says, Ohm's law implies that the alternator will only supply current as long as the battery voltage is low. 05; 140-578 *NEW* PMGR Starter for Delco PG260L, GM 12V 11T CW $99. Two wires isn’t intimidating at all. Found partial short to ground on main power wire to fuse/relay block in engine compartment. I = ignition - this is a 2 way current circuit that usually goes to the ignition switch thru a resistor wire or idiot light. Take a jumper wire and connect the blk/wht wire in the plug to ground of the car. Voltage at battery ~12V, at B+ on alternator the same. Features: Fits GM alternators with a 4 Pin oval connector; Weather Pack style seal; In-line 560 ohm, 1/2 watt resistor that allows but does not require a charge light; 8 ft.
