Will a Pertronic ignitor electronic ignition conversion from points type distributor work with a Duraspark 2 ignition module on the 300-6 engine?

 

I don't understand what you're asking. The Pertronix kit is a self-contained sensor + module. The Duraspark ignition module is a component of factory breakerless ignition. The two are completely separate from one another and would never get mixed together. If you are using a Pertronix kit, there is no need for any additional components. Hope that helps.

 

If you're asking whether you can use a Pertronix ignition with a DS II module, like fmc400 said, no, the Pertronix ignition has a self contained module and doesn't need anything else.
If, however, you're asking will the Pertronix module fit in a DS II distributor, that I'm not sure but I think the answer would be no. The Pertronix module attaches to the stock breaker plate in place of the points. The DS II doesn't have these attach points

 

The Pertronic ignitor must be a switch with fixed dwell angle, while the distributor pick up magnetic coil on the duraspark must actually generate a voltage.

Have seen the duraspark distributor connected to a scope with time set to 20 milliseconds and the scope measures a voltage pulse.

Wonder what would happen if the two wires from the pertronic were conected to the duraspark module....probably nothing, since the duraspark requires a voltage pulse where the duraspark module determines the dwell angle based on frequency of the pulse(engine rpm).

 

I guess I understand what you're asking, but it's not feasible.

Both Pertronix and Duraspark use a variable reluctance sensor (VRS) to sense the position of the distributor shaft. As magnets pass the sensor, a sinusoidal voltage develops across the VRS. The frequency and amplitude of the sinusoid are both proportional to the speed at which the magnet passes. The signal is very small (10's of mV) at low speeds. This small signal is amplified through an LNA (low-noise amplifier), which is then used to control the gate of a power transistor. Pulses from the VRS literally translate to the saturation and shutting off of the power transistor.

The only difference between Pertronix and Duraspark is this: in the Pertronix kit, both the VRS, amplifier circuitry, and power transistor are in the Pertronix module itself. This is because it is a self-contained upgrade kit. For Duraspark, the VRS outputs run up to the module through the wiring harness. The Duraspark setup is essentially the Pertronix setup split in two.

The two wires coming from the Pertronix module are for power, and the shunt to the primary winding of the coil. The module grounds through its mounting plate. On the other hand, the pickup coil inputs to the Duraspark module are the inputs to an electronic amplifier. They have nothing to do with one another. You would be delivering a signal that continuously alternates between ground and high-impedance, to something that expects a small-scale differential voltage, likely with a DC bias. The amplifier will rail, and the module will not switch. I'd also be concerned that it would damage the module.

 

Thanks FMC 400 for a great explanation and thanks raven 3 for asking the question
