Re: IH 784 Alternator wiring? You still need the warning light wire connected to excite the alternator when the ignition is switched on. [19] Transformation and rectification. - the Yellow wire off the alternator is also not connected to anything. Wire alternator per (Fig 3) Note: This wiring is most commonly found on Volvo vehicles. DEDICATED GROUND WIRE. This terminal is also active on 1 wire regulator equipped 10SI alternators. However, here is the weird part: With the EXC wire disconnected at the alternator, I can put a test light on the end of the wire and to the battery negative. Disconnect both battery cables from the battery with a wrench and tuck them away from the battery terminals before proceeding. One of the key differences is how the internal voltage regulator determines charge rate. Here is what you should get: Key off Brown, Pink and Purple dead. Alternator is self excite. Powermaster one-wire alternators for street use need between 1,200 to 2,400 shaft RPM to turn-on the charging circuit in a one-wire alternator, depending on the amperage rating. The white wire is connected from the right side (holding it) or left side (looking at face) of the male plugs. Or maybe it lights up only when accessories are activated. I found all the info on wiring the delco 3 wire at madelectricals website. The 3 wire unit's sound like they are harder to wire, but in practice, it is only 1 more wire to deal with. 1 Wire Alternator. Due to the 3G alternator's high output, use AWG-4 or AWG-6-sized wire protected by dual 14-gauge fusible links or a 150- or 175-amp mega fuse for the main alternator "BAT" stud charge-wire. Or maybe it lights up only when accessories are activated. Volt and Amp gauges monitor your vehicle's electrical system. Splice another wire onto it to make a Y. This was because a single 3/8" Lucar was rated at 35 amps, thus insufficient most alternator outputs, and also the wiring loom could have 2 thinner wires rather than 1 rated at 70amps. When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. The drawback of this arrangement is that if the warning light fails or the "exciter" wire is disconnected, no excitation current reaches the alternator field windings and so the alternator, due to low residual magnetism in the rotor, will not generate any power. So how does an alternator self-excite with no external power source when starting? P. White wire B+ from the main fusible link. When I was moving from Seattle to Monterey I took the costal route in my 1968 Land Rover 88. are you sure the starter is not 12 volt? i "correct myself" the 10si is a 24 volt alternator. 2) Connect a starter battery to earth and to plus terminal.

It sounds like you have a voltage regulator which the small wires would go to, the one with 12 volts would go through the rotor coils and come out the other small terminal where the regulator would limit the current to get you the 13+ volts and the required amps that are called for by the load on the system. What others are saying Auto Repair Tips And Tricks Every Driver Needs To Have Time-tested Advice About Fixing Your Car Problems. And there is one other wire off the alternator D- going to ground on the fan shroud right next to the VR. A wiring chart, based on amperage output and wire length, is included in the Balmar alternator installation booklet.

This means that the alternator stator is putting out lots of nice 3-phase AC for the tach to read. First is to send power with the ignition on and once it is all running, if there is a fault, the voltage regulator will ground the wire as it does when the alternator is not turning to indicate a problem. That is normal behavior when the exciter lead is not getting the reference 12V from the ignition switch, but the alternator is self-stimulated by residual magnetism. And also unlike most other so-called "one wire" alternators that actually need a second wire from the key switch to "excite" the windings to start the current production, the Reactor™ is completely self contained and self excites the charging system as soon as the engine is started and the alternator reaches it's energizing rpm (3). Other Delco alternators use that same wire, but require an additional wire from ignition switch to terminal I on the alternator to excite it. Use these convenient harnesses to adapt one style alternator in place of another. 2) When the alternator is not turning as when the engine is off but ignition on it functions to light the dash warning lights as a light test mode. As you might assume, the concept behind a one-wire alternator is that there is a single wire used to connect the alternator to the battery. without an initial current input from a battery).
