Spirit wont go forward

[ucla]

Hi can anyone give advice? My Spirit will not go forward only reverse. When I squeze the accelerator the ESC moves but the wheels dont and it works just fine in reverse. Steering is also fine, it just will not go forward. Any suggestions?
thanks!!!

The Spirit comes with a MSC, not an ESC. It uses two resistors to achieve 3 throttle positions in forward. You probably just have a bad connection or a bad resistor. Make sure all of the connections are good & if you have a continuity tester, make sure the resistors are still ok too. Since reverse is still working, those are the first things I'd check anyway.
