Alternator and Voltage Regulator Questions

I didn’t know all this when I started!
I agree that the parts store bench is not a good test, but out of the box if the store says it’s bad, like one of them today, grab another one.

Too crappy out to drive it on muddy roads today so i have to wait for a full run to determine over charging. No idea why jumper around the VR melted the wires. There was no resistance on the fld wire.

Also the vr706 and a 2 field alternator hooked right up without any trouble. Just needed a 1/4” spade connection instead of the ring connector. No additional wiring needed. The MoPar above didn’t work right out of the box.
