Thanks Bob,

The factory wiring on this Lucas 3 wire motor had the ground wire going through the park switch. Every revolution of the motor caused a dead short and a popped fuse. The wiper switch is hot in off and activates the park function. I put a diode in the circuit to keep it from feeding back through the ignition. Shortly after installation, the park switch broke so I had to disconnect it.

Am working on a park switch that uses a standard industrial limit switch to park the blades.
