If you hook a jumper wire straight from the post on a Delco single wire alternator to the positive post on the battery, should it charge if it's working?
The alternator worked before I started pressure washing and painting on the tractor, but doesn't now after I painted it. Angry Bob King and I theorized that maybe I sprayed paint in somewhere that it shouldn't have gone.
The idiot light used to come on when I turned the key on, then went off after the tractor started. After I sand blasted the dash and pressure washed in that general area, it doesn't come on anymore. I can't see in there very well, but I shined a light up there and felt up in there too. I can't see or feel any wires off.
I have no power to the post on the alternator with the key on or off. I hooked a jumper wire directly from the alternator and have 12.05 volts at the battery and the alternator both when it's running and when it's not.
