my hydrolic diverter wont stay down, if I put it in reverse it lifts the nozzle all the way up. I can run it down and lift it up by hand. The ram looks new and I think the problem is in the pump. Not sure if it's a bad solenoid or a check ball missing or stuck. Anyone else had this problem before? It runs up just fine but just won't stay down. I'm assuming that as son as I get on the throttle it's going to go to full up position and piss off anyone behind me. Anyone know of a simple fix?
