I’ve been so busy and I haven’t had much time. Sorry about that. I’m back now. Here’s the pictures he sent me- I’m hoping his cart hasn’t been flooded....

Ya, that cart has been swimming for sure.... Or left sitting in the ocean air for a very long long time.

That’s what I was unfortunately afraid of. Test the motor and if it’s good you can upgrade the controller to much better ones.

Luke, I would have him start with the solenoid checks for Pos and Neg activation and then if he has them, check the solenoid for closing and then current transfer across it.

And your motor test too, but needs to be for a SepEx, not a Series.... ;)

Luke, here is the way I do it with motor concerns.

Continuity and Motor Testing:
If you want 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).

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 0.8 to 1.2 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. 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.

You are right. My bad. I accidentally uploaded the series motor check....
