I've been plagued by an ongoing charging issue. Truck is a 1982, originally had a 22r, but I swapped to a 1980 20r. When I swapped the motor I kept the alternator from the 22r so that it stayed kosher with my existing regulator/chassis loom, etc.
The regulator has the irregular oval plug, with 5 blades. I'm hoping someone has the same setup and can identify for me the wire that I've realized was torn clean off at some point. The attached diagram should help explain what I'm talking about. Note the wire colors that I was able to best identify don't jive at all with any of the FSM wiring diagrams I have referenced.
I'm hoping someone can help me out with a color, or even better, the destination of where this wire goes (in regards to the alternator or vehicle loom)...Thanks.
