Hi hope all is well new to the forum, I have a 3020-30 and it will go backwards and forwards if really ease into the joey stick slow but other wise it just acts like it trips an overload switch it will let you try 2 times but then you have to cycle the power off then it will let you try to more times. I backed the brakes off in case that was the problem but it did not help. I don't have an electrical diagram for this old lift but it seems to me there is an overload switch or relay some were. Any one seen this before? any help would be greatly appreciated thanks.
