1949 6 volt coil
Is there any problem running the pertronics Flame Thrower coil with points and condenser? 6 volt pod ground system? It sure starts and runs good with that coil

Re: 1949 6 volt coil
Would depend on the resistance of the coil. They sell different ones, I just checked and some are .6 ohms and some are 3.0 ohms. They also have a .32 ohm coil. If it is the 1.5 ohm coil (which is what you need) it should be fine.

Re: 1949 6 volt coil
JSeery, please educate me on the results of the "wrong" resistance in a coil.
What about a hi voltage coil...? Thanks ! |

To low resistance gives you more current over the points then they can handle and they go bad fast...or even burn out catastrophic. Highvoltage is about turns ratio so not going to affect points life...primary resistance is what we want to be careful with. |

That's probably the best and simplest explanation I have run across. Good job! I can add that if you try to run too much voltage on the secondary ignition system on a flathead (an MSD box is a good example) you can have some serious leakage problems. Denny |

-6 volt coils should have a resistance of 1.3 to 1.6 ohm. -Amp draw thru the wire to coil should be 2.5 to 3 amps. Adjust the resistor to get no more than 3 amps. Terry |
