Working on an old 4 cyl Continental engine on an industrial loader, and can't get it to start or fire. Have pulled a plug, and shows weak spark. It has had a Pertronix Ignitor electronic ignition installed, and has been running, but after sitting outside for a month or so, now won't start. We started with plug wires and didn't gain anything. While messing with it, I could hear a click of spark when I was shutting the key off, and eventually stuck my finger in the wrong spot to get shocked by the coil one time that key was being switched off. It seems that what it is doing is when the key is turned off, it will jump a spark from the High voltage peg of the coil over to the minus terminal of the coil, or anywhere it can find ground I'd guess. Using an ohm meter, coil appears to be w/in spec, but not sure how to test the Petronix unit out. Any thoughts out there on what might be happening? Planning to call Petronix on Monday to get their thoughts too. Anything else that I need to check on to figure this out?
