I have a 1958 Ford 641 with a charging problem. It still has the original 6 volt positive ground system and is still using a generator. I had a charging problem a while back that required me to jump the regulator to get the red dash light to go out and the generator to charge.
Mysteriously, the tractor started acting normally after a while. I could start it up, rev the throttle a little, 1600 RPM or so, and the light would go out as it's supposed to. The other day, I started it and as usual, revved it a bit and the light went out and appeared normal. After mowing for a little while, I noticed the red dash light back on. I disengaged the PTO and mower, put it in neutral and revved it like I usually do. The light flickered but stayed on until I revved it to 2500. The light went out and I went back to mowing. The same thing happened again a little later.
How can I test to find the problem? I believe the generator works OK and I suspect the regulator again, but I don't like just throwing parts at it until it's solved.
