I have a Hyster B60XT serial number B199H05995W, that will just stop traveling at times. The contactor never kicks out when it happens, and it will continue to kick in and out whenever travel is requested. I have replaced the contactor, and handle harness(it was damaged in two places). I have swapped the handle controls, battery and controller with a known good unit. The motor tested good so I have not swapped that out, yet.
Once the unit stops, it takes awhile to get it to move again, unless you use the belly button, then it will move. Any ideas are greatly appreciated.
