External to internal regulator problems...help!!!!

[rustytruck50]

I've done some reading here on the forums before I attempted to upgrade my '72, so I'm not exactly coming into this cold. I have a known good alternator from my '82 c10 and I bought a adapter kit from M&H. I had read that there are times that the adapter wires are not put in the terminals correctly and mine was crossed & I corrected them. I followed the directions, seemed plenty simple and now the truck won't start.....no crank, no lights, etc. I have power from the battery, power to the fuse block and power to the alternator. I'm lost...it cranked & started like a champ a couple of days ago whend the fuel pump went south. Any ideas? Thanks in advance.

Put a jumper vehicle on your truck and see if the lights and starter work. If by chance the alternator adapter was right and you swapped the wires around it would drain the battery in a couple of days. You might still be getting voltage from the battery , but not enough to start the truck or light the lights.

Checking the wires to the alternator is easy. one of the wires will only have voltage on it when the key is on and it goes to the no. 1 terminal on the alternator, the other wire will have voltage on it with the key on or off and it goes to the no. 2 terminal.
