Before I ask my question let me say I have read through and checked everything on John T's list.
This is a 1972 IH 140, 12 volt, negative ground.
The generator went out while using the tractor a while back, had the generator rebuilt.
When I put the generator back on and cranked it up it was charging fine. I cut the tractor off, just so happened to be standing there while smoke started to come out of the generator, the tractor is off at this point. I managed to get the wires unhooked and the generator still checks out fine.
The lower contacts in the regulator stay in the down position only after the tractor is stated and shut down. The Battery terminal is the only terminal with voltage coming to it but with this contact in this position it is feeding power back to the generator trying to run it as a motor.
I have put a new voltage regulator on on the tractor an the same thing still happens. until I take the power off of the Battery terminal then everything is fine until I crank it back up.
Could something be switched inside the generator causing this problem? Any ideas that does not fall on John T's list?
