Bypass Ballast Resistor

View attachment 1650120 Yepper ..... That's the way to do it. You can't tell from stock.I did this very same trick, jumped the back posts. The Pertronix coil can now receive 12 v. I had replaced one on something and kept the old one and , walla, a freebie to modify, looks perfect.

I’m a switching to a Pertronix igniter and coil. There are 2 brown wires on the low voltage side of the ballast resistor, one to the coil and the other to the ignition switch. If I jumper the ballast resistor is it ok to send 12v to the ignition switch?

Second question. There is a small ballast? Between the positive post of the coil and grounded to the coil mounting bolt. Can that be removed?

The ignition switch is switching 12 volts.....which is the SOURCE of the 12 volts....

Where does that other 6v line go to?

The coil or ECU.....

Yes, you can jump the ballast. Or make the ballast a dummy by jumping it inside and leaving it plugged in for a stock look.

The thing you are calling a ballast on the coil is a noise suppressor and I’d keep that. Helps with the radio so it doesn’t have background noise.
