If hand controller is fine start by checking and load testing batteries as low voltage causes all sorts of issues.

good morning i,m now in the saudi arbia. i,m a korean .
Mechanic: spankyjr1, Journeyman replied 1 year ago

Okay, you also need to check wiring from hand controller to control box.

Batteries are number 1 cause of most electrical issues on these,, then dead man switch , then lift level/pothole/limit switches,, if they don't all agree it won't move using hand controller.

You can check your controller pot with power off and ohm out the pot if the resistance gradually increases or decreases your pot is good if it spikes up and down then your pot is bad and more than likely your pot is bad let me know if you need anymore info.
