1. Pulled out ignition switch and ammeter shows discharge.
2. Ran ground jumper from regulator base to grounded battery terminal post (+ post). Ammeter did not show charge.
3. Jumped generator “FLD” terminal to ground. Ammeter shows charge.
Does the fact that the ammeter shows charge when the generator “FLD” terminal is jumped to ground indicate that my generator is functioning correctly?
So, the flowchart says to replace regulator and I stopped testing at this point. I removed the regulator cover and observed the points on the shorter coil close the contacts when I started tractor and remained closed as long as the tractor was running.
Also for what it’s worth and ignoring TST’s warning of removing battery cable while running tractor, I removed positive ground from battery and tractor continued to run. One of Rachel’s way of testing charging system.
