A friend just acquired an EZGO electric golf cart it's an older unit that he was told hasn't run in a few years. Batteries are dead and brakes are frozen. Got brakes freed cart rolls easy. Charged batteries we got full volts (48) and that's where all our success ends. I'm a mechanic but not an electrician. I've downloaded wiring diagrams and tested for voltage at various points but have more questions than answers. What are the micro switches on the direction control for? I can make one click but it has to be moved manually the other nothing moves (no clicking noise). So I'm thinking both switches are junk. Any help and or suggestions will be welcome. thanks
