Electrical Tragedy! Dead ECU.
We have had some sort of electrical tragedy on the truck, with a 100% dead ECU :(
There is absolutely nothing when the key is turned on. Two new batteries got fitted and still nothing. The main engine fuses are blown, so something has sent a lot of current through things.
MAN have connected up the special computer diagnostics thingy, and it can't even see an ECU at all.
The bodybuilders have said they jump started it with a mega-battery starter pack, so maybe that is it? They assure me (and MAN) that they haven't done any welding on it at all. I was thinking maybe somone drilled a hole through some wires when they were fitting something, but there's nothing obvious to suggest this.
It is possible that it is a MAN manufacturing issue which will be covered by MAN warranty, but I am going to guess not. I'd be thinking it was something the bodybuilder did to fry it, but who knows. The MAN technician cheerily told me that a new ECU was about $4,500....
