I was curious, I learned how to drive on this car like 30 years ago, I still have it in Argentina (I live in Miami now) and I my mom (actually me) decided to restore it. For now the car have a carburetor but I still have most parts of the K-Jetronic (and some spares), which at some point after the restoration is done I will try to put it back.
Too bad I didn't see this forum before, I know this Bosch system because I studied most of them like 20 years ago, is a simple system, more mechanical parts than the LE-Jetronic.
I remember having a short circuit too, it was due to the positive that come from the key starter switch and it melted down (the one that usually go to the ignition coil).
I could have answered some of the question that you had before, I will check the other post, but not sure if I will help since we didn't have the Turbo edition in South America (only the Diesel version), but the gas it was 2.0 with carburetor or J-Jetronic, and 2.2L with LE-Jetronic, not the other Jetronic variants with Turbo (US market only if I recall correctly).
