Some times my golf cart will work fine then just stop

Customer Question

some times my golf cart will work fine then just stop working, I've checked the speed sensor also the battery connections are all brand new the low voltage I believe I have narrowed it down to motor controller or motor but not sure??
JA: How many miles are on the car? What size is the engine?
Customer: I couldn't tell the miles I just know its a 99 Ez go that i rebuilt with new frame and wiring and had it painted about 6 months ago a few days ago i moved my boat around the yard with it and now it is undependable
JA: What year is your Golf Cart?
Customer: 99
JA: When was your last tune up?
Customer: um never I do all my own maintenance new batteries 6 months ago all new beefed up wires new tires and rims lift kit etc as far as a tune up basically I grease everything and keep connections clean check batteries its def an electrical issue though
JA: Are you hoping to fix this yourself?
Customer: yeah I was I mean I think I know the problem but I'm having a hard time finding part numbers for the motor control I think mine is 300 amp but would like to bump up to 500amp
JA: What have you tried so far?
Customer: Just testing electrical input and output everything is getting power to where it needs to go I think it could be brushes in the motor or the Curtis PMC
