I have a 1946 farmall A that suddenly refused to start. I took out the battery and put it on a bench charger for about 36 hours. When I went to put it back in, I forgot about the positive ground issue and think I accidentally put it to negative ground. Naturally, it did not start. After several crankings, I realized my mistake and re-set the battery to positive ground. It still would not crank. Additionally, the lights would not work. So, I went and got a new 6-volt battery, set it to positive ground, and cranked it. It started up, runs like a charm but still no lights. So, I checked the voltmeter on the tractor while it was running .... It has four settings... The first, directly down in the off position showed 0 amps... The next two notches to the left and heading upward showed about 4 amps
... And finally the last setting showed about 13-14 amps. I'm now beginning to think my generator has bad brushes or needs complete replacement. The other thing I'm thinking is that by setting the bench-charged battery to negative ground by mistake, I may have reversed the polarization in the generator. Any thoughts on why my lights are not working?
