I am having problems with my personal boom truck. It is a stinger II TC-125 1. The hoist has quit working. All other functions working. I have moved the hoist hoses to the extend section and the winch works off that section. All the valves including the hoist valve are in one bank, But the hoist appears to be working off a seperate section of the vickers pump on the pto . Also I have pilot pressure to the hoist valve. Any ideas or explanations of the hyd circuit would be greatly appreciated.
