Help with "man" lift

[TTA89]

I have the worst luck sometimes. I borrowed a lift from a friend, he dropped it off in my garage so I can finish my ceiling. I'm tired of ladders.

He said something was strange, the throttle control only seem to work if you pushed forward or backward about 7/8ths otherwise nothing would happen. I tried to move it today and now it doesn't go anywhere. The wheels turn side to side with the control stick, the lift goes up and down but just won't go forward or backward.

I took the control box apart and there was a couple of screws at the bottom but I can't tell where they go/went. I don't see anything loose or cut....

Any troubleshooting tips? It's a JLG 2032E2, the batteries are charged, its been plugged in for a few weeks.

He knew it was broke when he loaned it,,, smart guy.

Sounds like the rheostat for travel has given up. The two found screws could possibly be to the rheostat so you might check the joystick area and see if you can see anything that looks loose.

I agree with TX, could be the rheostat, could also be the (forget the name ?Thyristor?) that converts the resistance received from the joystick into the motor controller.

Since the rheostat has a forward and reverse (same resistor or two?), usually the thyristor has a reversing contacting, and the same resistance input.
