Default Low speed/under load cut out

Got an odd one...

2001 REGEN 2 PDPlus setup. MCOR style toggle switch FNR

The cart runs great. BUT, under very light throttle, only enough to put the cart in a slow crawl it cuts out. And this is isn't a cut out like a flaky throttle, this is like a complete loss of power, but only for a brief second.

I have replaced the MCOR, replaced the solenoid, bypassed the solenoid activation function of the obc by running the negative of the solenoid coil to the negative of the pack, pulled the motor to check for dead spots, still nothing no change. I am starting to think the controller if faulty.. Any ideas?

Have you ever noticed it on throttle let up, or when your motor just gets you to the throttle position ?could be your speed sensor maybe the magnets are not in the right position or the speed sensors is not aligned properly

No, it's not the speed sensor, this is not an IQ cart, no speed sensor.

Yes all the time, not a heat issue at all.

Yes, how do you figure it does not work on a Regen? Removing the negative from the OBC and going right to the negative of the pack bypasses the OBC. The solenoid instantly closes, I test drove like this. So OBC is out of the picture, still does it.


I am leaning towards the controller.

Understand, but what I did would have removed it from the picture so it's ruled out.
