I have a 36V EZGO cart with this same controller and motor. My cart just recently stopped going full speed. Checked the motor, it's ok, did voltage drop test across the FNR switch and that is good, checked the Accelerator potentiometer, and that is good. Cart accelerates fine, just will not reach top speed anymore. Brand new batteries were also installed last week. Former top speed was 18-20mph, it will only go 12mph now. Could this be a controller issue or a brush issue in the motor?

Electricity is not my friend. What are you connecting the other ends of the jumper cables to? Can I just use a 12 volt car battery? Even though it's a 48v motor? Thank you in advance.

You know the way you taste in the motor doesn't tell you if it's burned and he still don't show you continuity across the post you have to check what is called multidirectional testing
