Winston, Im unfamiliar with that particular tractor, but in general terms, the charging system consists of the two wire AC alternator (under flywheel),,,,, ,,the rectifier block (2 wires AC in, one wire DC out),,,,, ,,then current flows to and through the ammeter (if it has one) to the battery. So, if the ammeter and wiring are all good and in place and the rectifier is good, the AC alternator wiring may be bad. It (its 2 wires) MUST be a contunuous circuit to work which you can test with an ohmmeter and neither can be shorted to frame ground either. I think they (alternators) put out somewhere around 24 to 28 volts AC at RPM, then after rectified (2 AC in 1 DC out) its around 13 volts DC. Be sure all wires are in place and theres no shorts, there should be 12 volts on BOTH ammeter terminals to work or theres a bad or missing wire or bad ammeter. Its been my experience failures are usually in a bad or shorted wire or the rectifier goes bad then the alternator wiring may become open or shorted. NOTE the battery has to be good and capable of acceptign a charge also as those systems dont put out much current. John T
