Hi Guys,

The discussion here is great. Here is where we differ in our opinion from Pertronix. The ignitor is designed to run on a voltage range. Minimum 12.8-13.4 volts, and maximum 28 volts. If you do not have the minimum voltage the unit will not spark. If you overvoltage the unit it could fry.

It is quite common for a 404 spinning high RPM's to be close to 28V if not a little higher. Having a 1 Volt cushion does not make us very comfortable. However, when running the unit at post ballast resistor voltages 17/18 - 21/22 volts we still have a pretty good cushion both on the undervoltage side and the overvoltage side. We have been installing and reccomending this method in our literature for 8-9 years. (As a side, pertronix tech support reviewed our instructions years ago and did not have a problem with them.)

It's worth another look. I will talk with product development at Pertronix and see what they have to say. I believe we are in the 3rd generation of the module and some things have changed. For example, pertronix use to warn against splicing the Pertronix wires, that warning has been dropped and replaced with (use quality splices...)

Two Tone, I would suggest you replace your coil and I'll bet that will solve the missing problem. Then you can deal with your overvoltage issue if it exists. Extended periods of overvoltage are one of the most common reasons for the 40611 coil to fail.

Cheers,
