1. HWH reservoir holds about 6 qts. You only use about 2 qts MAX when all jacks are extended.
2. You are NOT low and there will be NO air in the system, they are self bleeding
3. The wire you jiggled at the pump had to be the pump motor solenoid activation wire.
4. The pump generates 3000 psi and do you have the 4 levers (100 series) or just the 1 lever (200 series)? If 4 lever and when you activated all 4 levers and the pump did not extend any of the jacks, then I would say your pump motor is at fault. The single lever(Joystick) will also activate the jacks but usually in pairs and same thing. If no extension then the pump motor is at fault.
5. Last, have someone watch the jacks if you can get the pump to operate again. Kick down jacks can sometimes have rusted pivot bearings (the roller that allows the jack to swing down when pressure applied). If so, the jacks will extend straight backward and NOT swing down. If you do NOT release the levers to retract, those jacks will stay extended horizontally. But it would be very uncommon to have all 4 pivot bearings stuck rusted at the same time. Doug
