got a different alternator yesterday. put it on the tractor. check voltages before starting. had 12.58 at alt. starter, etc. don't see any bad grounds. the #1 terminal on the alt is hooked to a switched wire that goes to the gauge. this runs through a diode. #2 terminal on alt is hooked to the "bat" terminal on the alt.
started tractor. voltage went to 14.4 but had 14 on one side of diode (coming from the gauge) and 14.4 on other side of diode closet to #1 terminal. alt got hotter and hotter and started to smoke. unplugged and waited a minute. plugged in again and same thing happened in about 30 seconds. The alt on there is from "carquest" a 7127-3a 63 amp. 5th alt I have put on.
so, could I have a pinched switched hot wire causing this thing to over amp itself?
