I just bought my first golf cart and im im not sure how to tell what model it is. It is a 93 yamaha 36v. I am having problems with forward speed (about half the speed and power of reverse) any ideas where to start?


All carts should run a bit slower in reverse unless someone wired something backwards.

You can reverse a1 and a2 wires on the motor. (check for motor sensor first)

I have also seen this on club cars when the tach sensor fails on the motor (motor rpm sensor)

Check for a motor speed sensor first. This is a safety feature

If it has one of these it most likely failed.

If this has a yamaha speed controller it may be bad. I never liked these and I have repaired several of them. (mosfets short out) IRF-Z44 replacements if you want to fix them.
