SAME ANSWER I JUST POSTED ON ANOTHER FORUM You Polarize by momentarlily flash jumping NOT any permanent "taped" attachment. NOTE DO NOT FLASH JUMP TO THE GENNYS FIELD POST ONLYYYYY ITS ARM POST On a 2 wire Cutout Relay system that would be to just momentarily flash jump the cutout relays BAT input and GEN/ARM output together and you should get a spark. Same things accomplished by flashing the relays BAT terminal direct down to the Gennys ARM post. NOTE for Polarization to work the gennys Field post needs a ground current return path so you can temporarily dead ground the gennys field post to case/frame when you do the flash. It should already have a ground via the Low/High charge setting in the light switch and the field needs a ground current return path for it to charge you know which is dead grounded for high charge but via a resistor in the Low/High light switch for Low charge..... . Is the ammeter wired correct polarity??? If not it will register bass ackwards. If its wired correct if you turn on lights or ignition engine NOT runnig it should swing over to - discharge but then swing to + charge when running ifffff ff the genny is working. Was the tractor changed from Pos to Neg ground????? ???? That would explain a backwards working ammeter unless its leads were swapped. The genny can still charge at EITHER polarity but the ammeter needs corrected and the coil (if it has one) needs leads swapped also as its somewhat polarity sensitive. If shes charging the lights should glow noticeably brighter from slow idle to fast RPM and the batery voltage should rise from 6.3 volts to around 6.5 to 7 on a 6 volt system and double that on a 12 volt system. If that happens perhaps shes charging okay and its had a battery polarity swap and maybe all it needs is the ammeter leads reversed (check coil polarity also) John T
