Ohh I didn't know that it could be turned ... I just bolted it on.

About the cables.. I don't think that is the problem. I have a real fat cable (about the same thickness as my pinkie) going from the battery to the starter, and engine to chassis and chassis to body flat ground strips...
I guess I'm gonna check out this turning the starter around and if that dosen't work I'll have to get that heat shield thingy, or maybe both? How much clearance is needed with or without the heat shield ???
