96 Vintage Sepex Motor Test

I've pulled the motor from the cart. How do I test it to see if it is working or not?

If you want test the motor do this Continuity Test first. Place the Run/Tow switch in "Tow", (you may not have one if that us a Regen 1) 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).

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

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

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.

If you have removed the motor, you will need to clamp/secure the motor down so it doesn't jump when you energize it...

Thanks for the tips, especially the safety tips.

BTW, what is a 'personality switch'?

That is a switch to input different parameters (limitations) to the controller as we do with Alltrax XCT controllers.
