JFB .. I'm no electrical genius .. just the opposite. I think that the limit switches are suppose to connect when clicked and open when unclicked. I think that the limit switch tells the relay to stop or start powering the motor. The motor circuit is not directly interrupted by the limit switch. There is a lot of current operating the motor and the limit switches seem much to fragile to accommodate 30 amps or whatever they draw. But I could be wrong.
I may replace the limit switches just because of their age but I really think the relay is the culprit.
Rocky, thanks for the light tests .. very informative. For those with high powered headlights, if they were going to just park and hit the parking lights but accidentally pushed the rocker switch to the second position, those retracted headlights are going to fry the bucket covers. Very odd design.
I sense a headlight at the end of the tunnel.
