Thanks,,,that definatly helps,
In the harness going to the alternator, the brown wire is tied into the "L" terminal which is basicaly a line feed to the gauge.
The green wire is attached to the "F" terminal,,,,,it is what is called the exciter wire,,it excites the field windings in the alternator only when the key is in the "crank" position,,,this activates the windings, and also allows the vehicle to shut down when you turn the key off.
the blk/wht, i'll have to check.
In other words, if the field windings were to be continously applied with battery voltage,,,the vehicle wont turn off.
Do you have a voltmeter that we can do some circuit testing?
I think we can isolate it pretty quick if you do,,,,this is probably one of the most direct charging systems, and if you understand what i said about the field windings with the excite from the ignition switch, just let me know...i'll be happy to help.
