Hello, I recently bought a upright mx19 scissor lift that worked great for a while. Went to use it this last week and I have no drive at all, but can turn the wheels. Motor spins both ways like it wants to move but it just cant. But the lift also goes up and down just fine. If anyone has anywhere to start or something to look for, I chased a few wires from the platform to the control box inside the base to make sure they weren't broken and they were fine. Any help would be great. Hope everyone has a great day.
