pertronix failure

so i've burned up 2 ignition modules on my '79 sII, 345. i believe it is the Ignitor I, the p/n is 1483a. i'm also using their flame thrower coil. i know these are sensitive to leaving the ignition on, i don't do that. obviously there can be a couple seconds that pass from the time i turn the ignition for "on" to "start". is that enough?

as i'm writing this, i'm thinking back. a month or so ago, i installed a new steering box. to bleed the box, i had the ignition on to unlock the wheel. it was on for minutes without the motor running. i bet this is what did it.

does the ignitor II solve this issue?
 
I had gotten a bad 1483a from Summit Racing... I have a '72 345 and have the pertronix coil as well. I never left the ignition on and from what I understand that shouldn't be an issue with their coil?? I consulted with Pertronix tech support and they had me run the tests and found out it was bad. Ordered another 1483a and it fired right up....

thanks. i had a spare 1483a, swapped it out and it fired right up. since i have now had 2 fail on me, i'm scratching my head and concerned i could be left stranded. do you remember what the test was? i can run it to check the failed unit.
 
The II and III versions are supposed to have circuitry protection to prevent module failure when the ignition is energized with the engine stopped for a prolonged time. A matter of seconds is not generally an issue for any ignition system, but when you're dealing with minutes of exposure, best practice is to first disconnect the ignition power supply if the key tumbler must be left in the ON position for whatever reason.

thanks, hopefully won't make the same mistake again. i was so excited getting a new steering box, borgeson joint, etc i totally spaced disconnecting the ignition.
