They just had a ProStar in there that was hit by lightning. It blew out every sensor and electronic component on that truck. They were at $20,000+ in parts the last time I saw it. I believe they said it had been in the shop for over a month and was giving them fits, every time they turned around it was something else that needed replacing. I think they did get it running, but I recall they were having similar issues with the ECM/BCM. Seriously, I would call them, this was just a week or two ago and I am sure is still fresh in everyone's memory. Tell them Mike from Waterloo told you about this and to call. I hope this helps you out.

I have seen what lightning does to electronics. Years ago, I have had my fair share of repairing circuit boards that were completely melted out sometimes. I was even faced once with an old GE-1050 CNC control that got a direct hit. The minus 5 volts supply to all the large logic boards (about 8 of them) shorted out and went to +38 volts at full current. It literally burned out hundreds of logic chips. G.E. refused to give me the schematics for any of it and all the part numbers had been rubbed off the chips. It took me almost 3 months in my spare time to reverse engineer all the logic boards and repair them all but it was still cheaper than the $3600 per board to replace.
