Well guys you have convinced me to rethink parting out my newly acquired '55 TO35, so this morning I backed it into the shop to troubleshoot the generator charging problem and lift problem. Now there seems to be a dead short in the starter.
I used the TO35 12 volt generator wiring diagram from FENA. org to check wiring. It is a neg. gnd. 12volt system, the negative battery cable is grounded at the starter mounting bolt. I cleaned all the connections and when I got to the voltage regulator the Load terminal wasn't even connected. So I wired everything according to the schematic. I eliminated all the wiring for the lights and the light switch since there are no lights on the tractor. When I went to start it the solenoid clicked, nothing turned and the battery cables got warm. I thought something must be shorted so I rechecked everything. It was wired as per the schematic. I then disconnected the starter cable at the starter and using a battery cable jumpered straight from the battery positive to the starter post. The sparks flew and the starter did not turn. Shouldn't the starter turn when jumped from the battery like that? I can rock the tractor in gear and the engine turns so it is not locked up. It acts like a dead short in the starter motor, but worked just fine when I started it to bring it into the shop. The only thing I did to the starter during my troubleshooting was remove the cable to clean the contact and post. I don't know if the generator and voltage regulator are even any good, but I wouldn't think they could cause this problem. I'm not an electrician, but I can read a electrical schematic and I'm stumped. Does anyone have an idea? Thanks for any help you can offer.
