Installing new 6 volt coil quandary

Removing the old "Flame Thrower" coil and installing the new Flame Thrower, I ran into a mystery. The old coil was connected with the positive post running to a grounded nut on the radiator frame while the negative post ran to the distributor and then a wire running to the ignition out of the distributor.

Everything I've read says on the 6 volt system, you run the positive to the distributor and the negative to the ignition. Note that the distributor has an electronic ignition so maybe that is why the old configuration is set up this way?? I do know the wrong set up diminishes the power coming from these coils. Also, the plugs are gapped at .030 and it says I might have to re-gap the plugs a bit for the added spark power? I didn't notice any problems with the old gap with the old Flame Thrower coil....

I would like to see a picture of that please.

Thank you.
 
Electronic ignition systems use a different method of supplying a half wave DC current to the ignition coil and each manufacturer of such products may vary in their designs. Use that diagram for positive ground systems in the link for Pertronix ignition hook up.

I've heard that the Pertonixs systems are fussy about how they are connected. Any mistakes in connection will likely kill their module.

That's the route I'm taking. The old Flame Thrower hitch up is what I did with the new Frame Thrower coil. It's a Pertronix ignition too, so I figured why change the way it was. Took the car for a drive and all seems good.
 
It's on the power side instead of the ground side so it manipulates the power to the coil rather than the a breaker on the ground side. When dealing with electronics a designer can go either way as long as it makes the coil saturate the core and collapse the field to induce a high tension spark.

Pertronix calls it an igniter but that's just a term they use for their module. The part that actually ignites the mixture is the spark plug. Ignitors are used in turbine engines for lighting off the flame but they use high tension in the joules range to get the kerosene & gasoline mixed with air to light off.
