The simplest approach is to just put a corkscrew twist in the wire to shorten it a bit and keep it from rubbing on the housing or getting against the moving point spring. Also, the insulated conductor on most commercial condensers is made from high-flex wire similar to the test leads on a voltmeter to allow them to move repeatedly without getting metal fatigue in the wire strands. That's also a good idea on the wire from the coil to the distributor housing on a stovebolt, since the housing is in motion all the time.

Good tip Jerry. Years ago I ran across a friend who was dead on the side of the road in his Jeep Cherokee. I opened the hood to do some troubleshooting and discovered he had no spark. Digging further, found that the condenser wire had shorted just like you described. Rerouted it away from the housing as a temporary fix and he was able to get home.

What's really frustrating is when that short is intermittent- - - - -the engine starts and idles OK, but as soon as the vacuum advance starts to move, the bare spot contacts the housing. The result is a stutter exactly like the ignition is being switched off and back on repeatedly. If disconnecting the vacuum advance line either stalls the engine or makes the problem go away, start looking for a shorted wire, or one with strands broken under the insulation that open circuit intermittently as the breaker plate moves. Mid-1960's Ford V8's used to be notorious for getting fatigued wire strands between the distributor housing grommet and the points!

Awesome work on this Jon! We have been discussing on VCCA Chat and glad to see the work you have done. Yep, even the purists don't want the overseas junk and these condensers have caused even calm guys like Tiny to pull out his hair.

There are indeed very good capacitors on the market that will work very reliably as a replacement. They just don't look and mount the same as a condenser and you have done a great job making them fit this application. Fantastic legwork on these!

The cheap condensers available remind me of Dollar Store items - made to look like something useful but comprised of junk materials.

Great work Jon!

Thanks...I've sold the ones I made first, but when time allows I'll make more. Sort of hard to judge demand & interest. I thought about hiding the capacitor in a thin walled aluminum tube, but it isn't easy to find those in the USA. Once upon a time they were made for several things (including fluorescent ballasts), but I guess those days are gone. The nice thing is you don't see this item, so nobody will know it has been altered.

Just a thought, we have a company in the county that employs the developmentally disabled to manufacture simple items. If you have an outfit like that where you live you may be able to contract with them to put these together for you and sell a higher volume. The outfit here could easily cut the wire to a given length, crimp a split flag terminal on one end and solder the other end to the capacitor. It would lower your profit per item but vastly increase the number of items produced all while taking the burden of production off of you. The disabled working here put out very high quality items. It's a matter of great pride to them.

Those are very good suggestions and I imagine the same thing exists here. Once I get a feel for the demand, I may well pursue something along those lines.

Along another line, Jerry courteously reminded me these probably will find their way into other distributors and of course those won't operate in a fixed floor manner (like the Stovebolt distributor does). Here is an example of a note which will accompany each condenser shipment. If you see any errors or think I should add anything please let me know.

Looks good, Jon! Since vacuum advance systems (and distributors in general) are pretty much obsolete, a lot of people simply won't think about keeping the wiring away from moving parts. My grandson is making his living as a full time mechanic, mostly doing suspension work and wheel alignment right now, but I'm surprised frequently about his lack of "common sense" knowledge of how to deal with the older cars and trucks. I suppose if you didn't grow up around the older rigs, what used to be common knowledge isn't so common anymore!

Thanks Jerry. Common knowledge is largely held in cottage industries today...
