RE: 84 CGT no start
It sound like the ignition switch to me. They commonly crack the cheap
plastic housing and no longer make contact with the 15 terminal. The 15
circuit powers the ignition and fuel system and as is typical of Audi
they have too much current going through the switch. The steering wheel
and steering column switches have to come off so the steering lock
assemble came come off so you can replace the $10 switch.
Check for power out of the ignition switch from the 15 terminal, should
be a med/large black wire.
Audi sell separate wiring diagram books for almost all the US model cars
going back the 1978 5000's and the 1980 4000's. they can be ordered
through Dyment, I don't know what are still available. I have a list of
part numbers for the different books some where around here I'll post
them here if people are interested.
