Thanks Howard sorry I didn't make my a post a little clearer. I was referring to the one in Post #5 in this thread. I have the electrical schematic.

What I've discovered so far is the "Down Wire" on the electric motor shorted out against the motor's body. When the driver's side switch stuck in the down position it continued to provide current to the motor.

This caused the wire from the Lift Relay to the Ignition Switch (ACC position) to go through a melt down of it's insulation. Luckily the only damage was to that single run of wire. I was somewhat perplexed as to why the Circuit Breaker didn't protect the circuitry. It appears that the melted wire is 14 gauge. I would have thought it should have been 12 gauge.

Any thoughts on should the wire being 12 G as I'm getting ready to replace it this afternoon?

ADDED EDIT.

Looked at the amp rating on the breaker and discovered it is for 40A. Doesn't make sense the heaviest wire in/out is only 12 G, which is 20A or less.
