Christmas Tree - Dash warning lights: problem solved
Since these issues are sometimes squirrely to chase down, i thought i would post this for future searching reference if anybody runs into similar symptoms:
I have had my 91 C2 for a little over a year now. Ever since i have had it, i would periodically get the christmas tree effect with random dash lights and the sometimes that annoying buzzer, but ONLY WITH THE LIGHTS ON. Turning the car off and back on would get rid of it. This problem had recently become increasingly common and got to the point that it would happen every time i drove with the lights on and the restart trick could not shake it. This finally incentivised me enough to find a fix.
Having read another Rennlister had solved the problem by replacing the coil/distributor leads, I gave that a try. This indeed solve the problem. However, "while i was in there," i noticed there was a significant amount of greenish-white buildup on the Primary connection at the coil end. Since my symptoms grew worse over time, I assumed that if i left the coil alone, it was only a matter of time before this would happen again. So after a few weeks with no recurring symptoms, i changed both coils as preventative maintenance. Upon inspection, the top of the primary coil had a good bit of the same green/white residue.
I don't know if it truly was the lead or the coil. I suspect the coil as the leads looked fairly new and the coils looked original.

Great job. I ended up replacing the coils as well "while I was in there"... turned out to be in the same condition as you describe...so it was well worth the effort.
