91 ezgo slows down

[carson398]

I have replaced the microswitch on the pot assm. and the contactor. The cart is running but slows down after running a while. I am thinking it could be the controller. I have checked the voltage of the batteries under load while driving. it was about 36.5 to 37.8 volts. Any suggestions????

check your connections....especially at the motor. I had a loose brush stud causing the same problem.

Like fabbinman said check all your cable connections. Are any of the cables, controller, solenoid or forward and reverse switch getting hot? What is the battery pack voltage after the cart slows down?

the voltage has never changed i dont see any loose connections. I am planning on replacing the controller..
