Cat Lift Trucks (& Caterpillar) NPP20M:
Have a NPP40 that clicks but won't move

I need some assistance trouble shooting this problem. When I try to get it to move it clicks but won't move forward or reverse. It will if I hit the emergency button and will lift and lower. Can not seem to find wiring diagram or trouble shooting documents.
