I'm working on a SC4500, just replaced counter balance valve but have no hydraulic function. Pump is not engaging when you sit on the seat. You can't here the pump contactors click. It is a brand new contactor, also replaced the jumper diode. The pump FU2 200amp fuse is good. Seat switch is good. All fuses checked and found good. Any and all advise is very welcomed.
