Thread: Chevrolet Alt Charge rate

That wouldn't help your battery. You'll boil it dry and then go nowhere. I have the same exact alternator, and I thought it was a bad regulator too. BUT the manufacturer told me to run the alternator hot wire straight to the battery with no other connections and this fixed my problem(s) . as I said prior, I had originally had the alternator connected to the connection at the solenoid where the battery was also connected. This doesn't work. The alternator must go right to the battery terminal at the battery. Double check your wires, If the alternator is connected anyplace else, it will overcharge. It an easy thing to verify. If yours is wired ok, then we can go check other things, like pull the alternator and have it tested by a local shop. Mine would test fine at the generator shop, but back in the car it was overcharging!

I will not dispute what you are saying but it seems odd as the battery cable at the solenoid and the connection at the battery are the same electrically,

And I thought the same thing. But, it didn't work that way. The connection has to be at the battery. Even more interesting, when I was assembling the systems, the alternator would work just fine. But as I added more electrical systems.. then things changed. By the time I got the cooling fan wired in. It was stuck on full charge!
