This is the signal coming from the Inductive throttle sensor (ITS) through the Molex connector and wiring that was originally suspect. You should measure around 2.5 volts no pedal and increase as pedal is pressed. When the cart is not working repeat this measurement. It is hard to troubleshoot for this intermittent problem when the cart is working.
My first cart was very similar to yours. I had the same symptoms as you are having. This is why I came for help here on BGY forums 8 years ago. My problem proved to be the Molex connector was corroded and the ITS proved intermitter. That old cart was a real work horse when it was working.

…. And I didn’t even have to wait long. The cart is not working again.
Voltage across pin one and two (black and white) when the key is on and go pedal is NOT pressed is ZERO. Voltage immediately changes to 14.4 volts when go pedal is pressed. It stays at 14.4 volts no matter how far I press the go pedal.
