[86 911 Targa]

I've got a good quality scope so I'd checked all the inputs (which were OK) and the outputs to the ignition and fuel systems (which were non-existant) so concluded that the Motronic unit was faulty. I managed to temporarily blag one off a friend to prove it one way or another and bingo, the car fired up.

Cut a long story short I can't find a used one and the cost of a new one from my friendly Porsche stealer nearly made me fall off my chair. Now I'm fairly converse with electronics (I run a repair facility) but I can't seem to find any information (schematics and the like) on this unit. The ident is as follows:

0 261 200 051
911 618 111 00

Unfortunately (and understandably!) my friend doesn't want me to dis-assemble his Motronic unit to enable me to make some comparisons. So, any schematics would be gratefully recieved, as would any information as to which component(s) may have failed.

Cheers, John

John,
