So my 1980 el camino (350 engine swap) is having some troubles with the alternator. The first thing that I noticed is that the battery was not charging. The battery is only a few months old and holds a charge so I know it's not that. Then I noticed that the headlights and dash lights were not working. I brought the alternator in to get it tested and they said it was bad so I bought a remanufactured one. That one still wasn't working so I bought another one. Still didn't work. I decided to bite the bullet and buy a brand new one, but still nothing. There is power reaching the back post of the alternator, but none leaving through the side spade posts. When I supply power to the wires going to the spade posts and the headlights and dash lights work. Does anyone know what the problem is? Could I have just had terrible luck with buying bad alternators or is something frying them? Could it be a wiring problem?
