• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

'79 SII keep popping Pertronix Ignitor I

Full disclaimer, I'm a total ignition novice. when I got my '79 with 345 years ago, the OE Prestolite electronic ignition failed and I replaced it with a Pertronix Ignitor I (1483A) and Flamethrower coil. I only put about 2500 miles a year, it is a 3rd vehicle for fun. The first P-tron lasted a couple of years. Lately, I've been popping ignition modules, 3 now this year. I'll come back from a quick run around town, try to restart and it just cranks. I've lost spark and it won't start. I replace the module and and I'm running again.

I know not to leave the ignition on without the motor running as that an cause failure. I have the positive terminal of the coil and hence the positive of the module connected to switched 12V via the ignition switch, I just confirmed switched Voltage. I have 1.5 Ohms across the coil. I have about 1 Ohm from the mounting plate of the module to the negative terminal of the battery.

My cap, rotor, wires and plugs have less than 7000 miles. Does anything look obviously wrong. Any insight is appreciated.
Try the PerTronix Ignitor II next time. P/N 91483A
thanks. so i think i figured it out, total bonehead move (ask my wife, not the first time). i think it was the coil wire not fully seated into the coil. i replaced the module and as part of the process reseated all the plug wires and the coil wire. i then tested the module i thought had failed and it was working...of course, then i left power on it too long and smoked it. call it a $100 lesson. i've since bought another Ignitor I as a backup.
