Having a sepex motor adds another possibility to the list, but easy to check.
Just connect the DVM across the F1 & F2 terminals and monitor the voltage.

I screwed up on which terminals to monitor, should have been M- and B+.
I corrected it in my earlier post.

If the solenoid is staying activated while the cart is misbehaving, that pretty much narrows it down to an ITS issue, a motor issue or the F1/F2 cables.

Yep, the DVM on the dash is a handy little gadget.
You've got a high amp controller, so you might want to keep an eye on how far you are dropping the pack voltage under load.
Try to stay above 1.75V per cell (31.5 for a 36V pack) while accelerating and climbing.
Only take them down to 1.5V per cell (27.0V for a 36V pack) in dire emergencies, like getting off the tracks when a train is coming at you.
