TXT48 Low Battery fault??

[brokebuggy]

I have a txt48 here. Just installed new batteries and cables, when I took it for a test drive it felt like it would randomly shut off. Hooked up my hand set and found a low battery fault code. All the battery cables are new, solenoid to controller cables are good with new lugs crimped on and I replaced the solenoid. I can still feel it when driving, its not constant I would say about once every 1/4 mile and it only happens for a second then goes right back to driving correct. watching both the digital meter on the dash and the hand set I don't see a voltage drop when the cart seems to loose power.

Hey had a used controller on the shelf I forgot about, swapped it out and the problem is gone. The other controller must have a ghost in it. I assume the capacitor looses charge. Either way new controller on the way

Internal capacitors in the old controller likely got bad, leaky, high ESR, or bulgy. Cart was probably running off the pre-charge until capacitors couldn't carry the load.
