As some of you may know the engine in my 85 went on me. Since then I found a 22r and swapped over all the accessories (so it's a 22RE now ) and it's back in the truck and runs (not that well yet but that's another story) anyway ever since I put the new motor in I haven't been able to get the alternator to charge the battery. It was working fine before I swapped the motors but nothing. I've got a parts truck with a good alternator but if that's not the problem there's no since in swapping them right now. I already checked all the connections on the alternator itself and still no charge. Is there something else I should be checking?

Any suggestions would be appreciated.

 

Have you checked all the grounds from the engine to the frame, body and back to the battery "-" terminal?

 

You may have a bad ground to the frame. Was your truck originally a carb version and converted to EFI?
