I'm working on a Hyster R30XMS3 order picker that does not have any error codes, but hesitates or becomes jumpy when trying to creep in forward or reverse. It happens only when I move the travel joystick 5 to 10 percent of travel motion. After that, the unit speeds up and travels normal. It feels like the current to the motor is fluctuating. Replaced the travel potentiometer, calibrated, and it did not fix the problem.
Any help will be greatly appreciated.
