What would cause a wiring harness to fry... I had replaced coil, condenser, points, regulator, s/g and wiring harness and the thing was running like a champ... Saturday after getting my blade back from the welder, I was pushing snow and all of a sudden, smoke comes billowing out of the hood, so I shut it off and went to look and the copper wire was a glowing orange from the regulator down to the frame, it appears to be the blue wire from the s/g that suffered the most damage, however they all melted together. I did have a loose, but not disconnected ground on the s/g bracket, would this have been my monster or is there soemthing else. The regulator is fried and I am not sure of the damage to the S/G or other parts, so any input would be huge...
