  1. Yes, I used a 12 volt battery, but my truck is 12 volt. Does anyone have a wiring diagram for the Model 75 Truckmaster heater? Has anyone found a source for heater cores??? I'm taking the motor to a local shop that may be able to rebuild it tomorrow. Thanks for the advice.
  2. My fan motor died yesterday. Any idea where I can get a replacement?
  3. ggdad1951 Thanks for the reply and help! I finally figured out how to get at the motor fasteners and completed disassembly. The face behind the medallion panel had pristine paint, so I had the color matched in PPG. The painted pieces are going for plastic media blasting in the next few days (70 miles to the blaster). There are 4 wires coming from the motor. Only the yellow and black wires were connected. The red and green wires were cut off and not connected. I touched the yellow wire to the plus side of a battery and the black wire to the negative side and the motor ran. How is the motor supposed to be wired???
  4. ggdad1951 You said in an earlier post that you restored some truckmaster heaters. I took my Model 75 heater apart this afternoon to rewire it and haven't figured out how to remove the motor to get access to the wiring. HELP! Any tips on heater restoration would be a great help. Thanks
