I've been chasing a no or intermittent battery charging problem for quite some time now. The problem started when after 72 years, the original Auto-Lite regulator stopped working...a pretty good run for an electrical component! I took the generator and regulator to an auto electrical shop to test. They said the generator is good and regulator bad, so they sold me a new regulator. I got everything back on the tractor, started her up and saw that the ammeter was showing about 5 - 10 amps on the + side which is good I was thinking. I turned the headlights on to see how much it affects the charging and the ammeter swung over to a couple amps on the discharge side and after I turned the lights off, the ammeter stayed in the center. I noticed if I rapped on the regulator housing it would begin to charge again, but not for long. I seem to recall that with the old regulator the ammeter would always show a slight needle swing to the right while the tractor was running. Is this normal for a new regulator. The new regulator is made in India and wasn't exactly cheap.
