Can anyone tell me if you can run your old coil with the Pertronix ignitorII, or do you have to also have the Flame thrower II coil.
Thanks in advance. |

I'm using a standard Bosch 'Blue' coil. Just need to make sure the primary coil is the correct resistance the Pertronix requires (I think it's 3.5 ohms, but don't quote me)

go here
Pertronix Instructions and especially here - pertronix Secrets your old oem coil kicks about 25K volts a flamethrower is 40K as i recall depends if you are going to enlarge the spark gap or run high compression, etc |

Ignitor II takes the 0.6 ohm coil and needs spiral wound plug wires, not standard wires.
Regular Ignitor unit can use the 3.0 ohm Bosch coils or Flamethrower. |

You can use any coil you want with the Ignitor II down to 0.45 Ohms.
Anything of greater resistance, like the stock 3.0 -5.0 Ohm, is ok just not optimal (less spark). RECOMMENDED FLAME-THROWER COILS COIL # PRIMARY RESISTANCE DESCRIPTION 45001 0.6 CHROME - OIL FILLED 45011 0.6 BLACK - OIL FILLED 45111 0.6 EPOXY 60104 0.45 HV The Ignitor II ignition can be used in conjunction with most ignition coils rated at 0.45 ohms or greater. For optimum performance purchase and install the Flamethrower II high performance coil. They say you MUST use non-solid core wires however: • DO NOT USE SOLID CORE SPARK PLUG WIRES. This is because the Pertronix makes a lot more EMI noise and the coil wires will help suppress that. I used MSD 8.5mm Super Conductor wire and made my own wires. |

Thanks, I'm helping a friend fit a Pertronix and we couldn't find the old model for non vacuum dizzys. So opted for the pertronixII. Now we have all these extra costs. Me thinks that's why the 1847 is no longer listed on the P----an site. Not that I think any vendor would make you spend a load of money unnecessarily.
Anyway I'll ring them and if we can get away with the poverty Pertronix we will. |

Use tried and true blue Bosch. I have a spare if you want it for free.
