6 volt to 12 volt conversion

[JSeery]

Didn't look at the links posted above, but you need to get the coil straightened out. With 12v neg ground, the + side of the coil goes to the ignition switch and the - side goes to the distributor. Need a 12v coil that has the proper internal resistance or a coil and a ballast resistor. What you need to end up with is around 6 ohms, either a 6 ohm coil or a 3 ohm coil with a 3 ohm ballast resistor.

I thought it was 3 ohms...either by a 3 ohm ballast resisted fitted coil or a 1.5ohm coil with a seperate 1.5 ohm ballast resistor?

Please clarify as Im in the process of doing this at present on my 36,

Thanks.

You are correct, must have been half asleep on that post! or maybe completely asleep.

Corrected the ohms!!!

Double post!
