Hi, all My V12 decided to stop firing. Was told to have the external amp module checked. Sent unit to "expert" here in South Africa. "Expert" duly misplaced/lost my amp. And of course there is nothing/no-one here to help me. Q: are there 2nd hand units available in UK and cost?.
V12 is 1981 model (acc. to VIN no. ) The module (internally) only a cap, some ic? (number GM 1178813) and something that looks like a resitor?
It looks very plain and simple indeed. However without the proper specs, there is of course a problem. Book says that all parts can be simply replaced. If anyone knows which parts to get, its connecting arrangement and output wiring, to the distr. coil etc, perhaps I can do something.,.. Thank you Jean

 

the only one in the uk on ebay who will post worldwide I can find is this
whether the wiring connector is correct for your model/type.... you had better check

The module is AC Delco D1906

I think the cap can be a garden variety generic....not sure.

However, I've yet to find anyone who knows the value/spec for the zener diode.

Even if you got the individual parts you'd still need the casing to properly house everything.

Cheers
DD
