Alternator and Voltage Regulator Questions

Test it ON THE CAR. Not that difficult Go to MyMopar and download a shop manual, and an aftermarket wiring diagram, There are also simplified diagrams there of the alternator / regulator

I divide things "roughly" into

1.....The charge circuit path, that is the alternator output, through the bulkhead, the harness, the ammeter, back out the bulkhead, to the battery

2.....The field circuit.......from the igntion switch (branches off at the coil resistor)-----to the VR---------to the alternator field

THE VR MUST BE GROUNDED. Unbolt the VR, scrape and clean around the mounting holes, and remount with star lock washers

3.....The major components, IE the alternator and the regulator

=============================================

"Quick test"..........Done in the following manner, this will leave everything in the circuit EXCEPT the VR

Unhook the VR wires, and jumper them together with a clip lead. Start the car while monitoring battery positive, and slowly bring up RPM. Your dash ammeter should move to the right, and the voltmeter should climb. If it does don't allow it above 16V

If this is the case, check the VR grounding above, and if that is OK, replace the VR
