I don't understand. This IS a standard "70's" Mopar alternator? And not something like a powermaster? Can you shoot a photo of it showing the back and terminals?

The field is a simple electromagnet, connected to the two field terminals. The light blue wire supplies 12V from the switched "ignition run." With that connected, and key "in run" you should read "battery" at the green field wire when disconnected at the regulator. The VR controls "the amount of grounding" on that green wire and that controls alternator output. IF the alternator is charging with the VR connected, either

the green field wire is grounded
the field is grounded on the "end" opposite the blue 12 supply wire
or this is an aftermarket alternator with a built in regulator, and IT is acting up

I don't understand either , this is all new to me . I am really lost . Thank you for your help .
The alternator is a remanufactured REMY unit , I recently got from rockauto . It's supposed to be a direct replacement . Pictures below .

This thing is charging with the VR disconnected too . though occasionally it does not charge at all . VR connected or not .

With the terminals connected , and the VR disconnected . With the key " in run " . the green wire is reading only 0.04 on the meter set to 20 . The blue field blade is getting around 10.00 .

this Alt. is probably crap , but maybe something else killed it ? I just got three used alternators at Carlisle . Two standard 60 amp two field , and one powermaster single wire , 90 amp with built-in regulator . maybe i should try one of those ?

Would any of this be caused by / or causing the grounding issue with the lights ? or would that be something different ?
