PQ Bandit? 36 Volt car? I see a lot of problems here. The PQ Bandit is advertised on their site as a 48V IQ motor. That may be your problem. Let me know more about what you've got. The battery voltage readings you listed sound like a 36V battery pack to me. You also said it's a resistor cart. So that definitely leads me to believe it's 36V. The PQ bandit is definitely not designed for that, according to their site.

Tahoe, maybe it isn't a Bandit. The motor is the original 36V motor, rebuilt by PQ, and returned to me a purple powerful motor. I thought that was the Bandit and according to the website, the Bandit upgrade is good for 36 and 48V motors. I'll check with them to make sure. Yes it is a 36V cart. So why would it run fine for 6 months and then just drop to 50% or less? I pulled the wheels to check the bakes. They spin like a couple of roulette wheels so no dragging. I let the cart sit for three days and checked the voltages again. No changes, and the specific gravity is the same too. I rechecked all the connections, pulled apart the VGlide, and looked over the FR switch. I can't see anything odd.

36V 1989 series resistor cart, PQ motor, 4G cables, BU solenoid, VGlide wiper, all less than a year old. FR looks great. Brakes are free. All connections tight. BAtteries charge normally (20 amps down to 8 amps).

From the PQ Bandit page:
We can upgrade any DC brush motor. Below is a sample of cart and/or motor manufacturers that we have successfully upgraded

**36 volt carts with only the Bandit motor upgrade should get around a 20% increase in both overall torque and speed.

If the batteries all LOAD test good. And the V glide and Resistor coils all look intact and good. And the wheels roll freely...Might be worth sending the motor back to PQ and asking them to check it out?

How should I do a load test?
