Leroy is sending me a flight systems 40 inch cable. Im also buying three used PMDs (flight ) from Pensacola Fuel injection $85 delivered. Hopefully it cures the problem. I keep looking at the cable and all i can see is insulation missing from one wire and it doesnt appear broken. maybe current is jumpimg and grounding out on the next pin over???? I still don't know if its the problem, but its certainly A problem. And I've seen stranger things happen. I'd like to make a short video of the FSD heat sink vibrating after it warms up, I can believe how bad it is. Ill have to investigate further because I don't remember it vibrating like that.!!
