Re: What's the deal on 6 volt coils?

Coil tests are generally almost completely useless in diagnosing coil health. The most common symptom of impending coil failure is that all is great when the engine starts up cold, and ignition gets erratic as the coil heats up. Simple enough to check - just go to NAPA and get a proper coil and hook it up temporarily and go for a test drive. Just been down the same road with a coil on my 34. Leaving the ignition probably didn't do any harm, and anyway it would depend on whether the points were open or closed at the time; generally points will suffer more than anything else.
