I am troubleshooting a JLG 2032ES. It lifts fine but won't drive. There are no error codes at Platform Control Station. Checked service manual Section 5.8 and did not find relevant info.

Thought it might be a pothole switch, one was sticky but when I depressed it I got the 2-5 light flash error, cleaned out the switch, works fine and error went away.

Double checked parking brake.

The machine is in fairly constant use and did about six hours of work before freezing up and had to lower it and forklift it out. Horn is disconnected, don't know if that matters or not. Voltages are all good.

Any help would be appreciated!
