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.

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
