I put a different reverse switch on it, machine is working fine now. I guess it was the problem the whole time, I don't know for sure. Since I swapped many components. But I did have 36v at fwd and rev switches at TB11 when I first started. I guess if you have voltage at these terminals it doesn't mean the switches are good. Anyways thanks for all your help guys. Now I just have to replace the rear wheels and machine should be ready for service again. which is a job because I just did them on our other lift.
