No Travel

The Hydraulics work, but no travel fwd or reverse. When I move the handle to drive fwd or reverse the unit jumps twice and then contactor opens. I have checked directional switches - all under 5 ohms. I checked both brake switches for battery voltage across them with pedal depressed. I checked the accel pot, seems very erratic, at neutral it measures 5k ohms, but as I move the handle forward or reverse, the reading is all over the place and does not go to zero ohms at full fwd or reverse. Any help would be appreciated.
