I'm installing a Pertronix Ignitor in my '67GTX/440. They recommend bypassing the ballast resistor. How do I do that? Go easy on me...I'm new to this stuff!
Thanks,

Bypass Ballast Resistor

Purchase (2) of these connectors, install (1) on each terminal of ballast resistor. And next make a short cable with female tab connectors and jumper the ballast resistor. Note that this method will retain all of factory wiring, no cutting required so U can return back to the origional OE wiring layout if ever desired. The connectors are available on line or from Napa.

I'm not concerned with a purely original look. I took both the blue & brown wires, coming from the bulkhead disconnect (big bunch of wires & 3 big plugs on firewall), that go into the ballast resistor and splice those two together + also splice in the blue wire coming out of the ballast resistor. Then you can just remove the ballast resistor

Just make sure the coil you intend to use is compatible. The Pertronix unit just switches the coil on/off. Consider using their coil....if in doubt, call Pertronix and ask......

Gut it, solder in a wire, re-install. I epoxied mine after I was done otherwise the wires moved around.
Pertronix recommends their Flamethrower coils.
I believe with the Pertronix 1 you can use stock coil and keep the ballast.

Yes, hiding the wire inside the ballast does make it look like you didn't do that. Will next guy know that, if he changes something? Yeah, don't worry about the next guy. I do like it, it's just that you are the only one that knows it.

I have a gutted ballast, petronix coil, got a dry transfer to add oem writing to the coil.

Hoping to not sound like too much of an idiot, why exactly are we jumping the ballast? My car has the ballast jumpered out by the PO. its one of the things I was going to fix up. (the job ids not very well done)

The coil will now get the full 12 volts.
So that the coil has higher output voltage.. But depends upon the entire ignition system and matched components including ECU and distributor..

The coil you are using determines whether or not a bal res is reqd with it. The Pert unit is just a 'switch' in this case that switches the coil current on/off. Bypassing/removing the bal res will burn out the coil if it is designed to be used with a bal res.....

Very simple... for a Pertronics conversion, just remove the resistor, solder in a solid insulated wire from one terminal to the other in the back side, then re-install. That will maintain the stock look. Make sure you replace your coil with one compatible with a 12 volt system.
