Sorry if I'm way off the mark here but I haven't time just now to read the whole thread.
A couple of winters back I was alone and asleep on my boat when I awoke to the sound of one of the engines running. The subsequent events were virtually identical to those mentioned at the begining of the thread. Although wiring was burnt the actual cause of the engine starting on its own account was found to be moisture in the flybridge ignition switch which caused a short and started the engine. The engine concerned was a Volvo TAMD31B and the engineer advised me he had heard of this happening before on certain older Volvo units.
This may not be the same cause in your case but it certainly lead to very similar events. It wasn't a latent defect as such, just unfortunate circumstances.
If I'm talking a load of tosh excuse me but as I said I haven't had time to digest the whole thread.
