[QUOTE="69ST, post: 185741, member: 5"] I'm inclined to agree that neither coil has failed. It takes more like 10kV to get a spark to jump a plug gap but, getting that requires a minimum rpm, even when kicking-over the engine. It also requires that everything is working properly. At this point, I think you've narrowed things down to points or/and condenser. Next step, try cleaning the points. Start by running a piece of of "shirt cardboard" between the contacts, followed by a shot of solvent (brakleen works well), then 2-3 passes using 600-grit (or finer) sandpaper and then a final shot of solvent. If that doesn't do it, not much choice but to try throwing another condenser at it. Condenser quality has slipped over the last decade, once in a while someone gets a defective part. It's also possible to kill a new condenser while soldering the lead, unintentional overheating is easy and, we've seen more examples of this than condensers that were defective. [/QUOTE]
