I checked the lead wires carefully last night , with the beep on my multimetre also and could not find an intermittent or total discontact. I was tempted to order a second ignition but now I am wondering which one ?? My unit is the synchro spark and I could not be talked into mech. advance. I ran a Pro-Spark for hundreds of hrs with only occasional wiring probs but they seem to have gone into the shadows also.
I will call C&H , I guess they do not have e-mail, prefer to call anyways.
