JLG 771 error code 2032ES OPEN CIRCUIT DRIVE MOTOR

2032ES, will not drive. I have the diagnostic connector and displays 771 error code which translates to OPEN CIRCUIT DRIVE MOTOR wiring. Is this typically from a fault inside one of the motors? Controller? It beeps, then immediately stops in FWD and Reverse.

First off you can go to JLG's website and find the service manuals section, then navigate to your model unit and go to the section you need for the service portion.
look it up by serial number of your unit and you can download it.
then...
i would go to the section 3.5 in the service literature dealing with the drive motor troubleshooting and follow those steps in checking the motor circuits. I'm looking in the newest one and it shows starting on page 3-21.
It will have you check the motor itself, also check the wiring connected to the motor.
It has a step by step guide on how to check these circuits.
