cat 321 heater motor issue

Jrd equipment ยท 2014-02-06 14:32

I had a noisy heater motor and put up with it until it quit. I replaced the motor and still not working. There is 28 volts to the motor. The new motor is fine and just to see I shorted the power to ground at the motor plug. Not even a spark but my meter shows 28 volts?? Anyone have a suggestion? alberta cold

    Bad ground. Hook the motor up to the factory plug then run a jumper from the motor ground wire to a screw or something metal that's grounded to the machine. See what happens Sent from my SPH-L710 using Tapatalk 2
