Anyone else running Pertronix ignition? A couple of years ago, I bought their cast, stock look SVDA distributor with an Ignitor II module, along with a Pertronix Flamethrower II coil and the recommended wire set in an effort to cure the terrible off-idle stumble I was having with the mechanical-advance only Magnaspark II distributor that came with the car. Once I got the vacuum sources from my dual Dellorto 40s combined and sorted through a homemade restrictor to smooth out pulsing, the car became way more driveable. Until this past Sunday, that is.
I was with the wife, purring along the back roads of Western Maryland two hours from home in an area with no cell service, when the ignition quit. After a bit of troubleshooting I determined it was either the coil or the module, neither of which I could fix. Thanks to some very kind folks living across the road from where we broke down, I was able to make some calls.
The roadside assistance plan included with my insurance policy was worthless, they couldn't find me in their database. My AAA subscription also turned out to be worthless, they no longer let you ride with the driver because of Covid-19, at least not in Maryland. A call to family arranged a ride home. The folks we met loaned us a car cover and tarp in the event it rained overnight. I came back the next morning with my trailer, loaded her up, and hauled her home.
Troubleshooting with a quality multimeter instead of the Harbor Freight unit I keep under the seat for emergencies revealed a good ignition coil. I also tried a known-good spare coil for grins and giggles, null joy. After checking for proper grounds, voltages, and coil resistance per Pertronix's recommended troubleshooting procedure, I determined the module in the distributor had failed. I ordered a new one online, then dug into the warranty and found it covered for 30 months, so opened a support ticket with Pertronix also. If all goes as planned, I'll have a replacement in a week or less, and a free spare on the way.
So here's my full question: does anyone else run a Pertronix Ignitor II? What's your experience with reliability? I had about 5000 miles on mine when it failed. Is this common, or is my recent experience an outlier?
