Turn key on, motor gets hot immediately

bird_4_3 · 06-10-2019, 03:14 PM

I put new cables (2 guage) on my cart. Have played 10 rounds or so with them on, along with a new pivot rid and mcor I replaced. Anyway, my cart would not move today and when I turned the key on I could smell it, even before trying to move it. The motor was super hot. Any suggestions? Figure I need a new motor, but I do not want to put one on and the same thing happen.

Not sure if you have a Series or Sepex motor so this will cover both as applicable. To test the motor do this Continuity Test first. Place the Run/Tow switch in "Tow", (If you have one) then disconnect the pack and then all the cables from the motor. (Be sure to double wrench every motor post/stud when breaking them lose or you may break them off. Spray them down with penetrating oil prior to doing it). If you have a Series motor some will have S1/S2 in place of F1/F2.

Get out your DVM and set it to the Continuity setting and:
- Test between A1 and A2 (Beep)
- Test between F1 and F2 (Beep)
- Test between A1 and F1 (No Beep)
- Test between A1 to Motor Case (No Beep)
- Test between F1 to Motor Case (No Beep)

Now flip your meter to Ohms/Resistance and:
- Test between F1 and F2 and you should get 1.0 to 1.6 Ohms (Sepex only)

If all those are correct as stated above then you can test the motor:

To test run a Series motor:
With all cables removed from the motor, jack the cart up at the rear and connect a jumper from A1 to S1. Then connect 12 volts positive to A2 and 12 volts negative to S2. (swap S1 and S2 to change rotation direction) You may want to have a disconnect switch in-line with the power supply as some do and some do not....

To test run a Sepex (regen) motor:
With all cables removed from the motor, jack the cart up at the rear and connect a jumper from A1 to F1 and then a jumper from A2 to F2. Connect 12 volts positive to A1/F1 and 12 volts negative to A2/F2. (swap F1/F2 jumpers to change motor rotation) You may want to have a disconnect switch in-line with the power supply as some do and some do not.... And remember that you are only "testing" the motor so you don't want or need to engage it very long.

The motor cannot get hot on its own it needs power
