After you swap the F1 and F2 wires, your direction of travel will be fixed. Then we can address the jerky operation. This is either due to a bad MCOR or a bad speed sensor. It's most likely an MCOR issue. Open the Alltrax Toolkit, go to the monitor tab, with the key on and the F&R switch in neutral, move the accelerator and watch the throttle percentage on your computer screen. It should be a smooth constant motion between 0-100% throttle. If it's jumping around and not staying consistent, you'll need to replace the MCOR. If that looks good, you may have a speed sensor issue. The XCT is very violent when the speed sensors are intermittent. If the sensor is intermittent it causes lots of jerking. For instance, if you start to move and the speed sensor is monitoring motor RPM, but suddely stops and drops to Zero RPM, the cart will jerk and come to an abrupt stop. The Speed Sensor monitoring can be turned off for test purposes. Un-Check the box that says "Enable Speed Limit" and save your settings. If the issue is now resolved, replace your speed sensor and turn the speed monitoring back on, save your settings, and enjoy.
