Yes, jump, short, somehow bypass the switch and see if the chair moves. In 4 of 5 cases, I have had to replace the switch. Its the only part I carry with for "spares". Its an easy fix, and a lot cheaper than replacingt the whole hand control.

If it's stopping in the same spot, it is a limit switch that isn't making contact with the lift sensor.
Here's a link to the wiring diagram that shows where the limit switches are.

If it is tripping the circuit breaker, either your are trying to lift too heavy a weight, or the motor is pulling too much amperage due to previous abuse, or misuse. These are good lifts, and if you bought it new, then get ahold of your dealer and Pride will fix the problem. If you bought it used, they may have been using it to haul concrete...who knows?

Providing you have power to the chair, this will be a faulty handset or a faulty limit switch inside the actuator assembly.
