No error codes on the display? It might be the dreaded 66 code. When this happens the car might go forward but not backward or vice versa. It can be fixed but it not fun, or you can have the controller rebuilt or you can covert to AC motor and controller. All this if it is actually a 66 error if not I am not sure where to point you. > [@66 error code](https://community.electricforum.com/t/66-error-code/6503/25): > > OK Dave, Looking for direction here… My guess is that the four Mosfets that are black on one side are what we are looking for. The two Mosfets on the other side look just slightly different than the others on that side, do you think that would be the other two? Since forward gives the 66 error and reverse does not, start with the four black ones? or just do all six? @Inwo [Controller2] ---

If your controller is bad I would recommend upgrading to a T4/T5 . The T3 that came stock is not performance upgradeable . The upgrade will give your Gem a noticeable improvement. ---

> [@Gem\_e2](#): > > bad forward reverse Could be. Would it “wrench” with no code? That’s a tough one. Keep the throttle down to look for code. A throttle error may reset at zero throttle. And why only reverse? The switch, wiring, motor, or controller are the only thing I can think of. Reverse your field wires. Follow the the symptom. ---

Ride 4 fun doesn’t fix them , they send them to Flight systems for repair (fsip.biz) , you can too .Flight systems wont program for high speed. For that you can install a MAgic magnet (inwo on here sells them) this will remove the governor and let your Gem hit it’s speed potential, probably low 30’s . What top speed are you looking for? ---
