12 Volt Sparkplug Coils

[Glen]

I have had several people ask me for an over-the-counter part number for 12 volt sparkplug coils to be used in a 12 volt conversion, something that would be available locally not requiring a special order. This is an extensive list of coils that do not require a ballast resistor, they can be installed with no modifications necessary to the wiring harness. I also tried to include any I could find for our friends outside USA incase they needed a part possibly local to them. Hope this helps.

Glen, what is the primary differences in all these coils? Does it make any difference in which one I purchase? I am making the assumption that you mean they all have an internal resisitor so that you don't need an external ballast resistor, is that correct?

Thanks for the list. You should consider putting it in the appropriate place on the G503 Wiki, look at the above header for the location of the wiki. Then just put it under the coil part.

[Herb Tate]

If I am not mistaken they all have an internal resistor. Glen please correct me if I am wrong. I just purchased a coil from NAPA with an internal resistor and replaced my 12V coil that didn't have one. I also found my old coil looked like a soda can that was left in the sun. The bottom wad bulged out The jeep still runs rough when it gets warm. @#*! heat riser.

[M38JEEPER]

I would suspect a heat riser problem, seems to pop up here on the GEE many times. I find coils at the local auto wreckers all the time, lots of 12 volts lying around, basically free at the autowreckers I go to. I would replace the one you have with the bulging bottom, sounds like she's going to blow!!

[Herb Tate]

I did. I bought an internal resistor type.

[Glen]

ALL of the coils listed above have internal ballast resistors, they do not require external ballast resistors, they should easily replace the exsisting coil. With the exception that they are from different manufacturers and possibly a small difference in shape, they are basicly all the same.

As for coils lying around the auto wreckers, they have not made a points type ignition since 1973ish so there is no telling how old those coils are. Also, almost ALL stock American cars and trucks, along with the biggest majority of foreign cars and trucks, used an EXTERNAL BALLAST RESISTOR TYPE COIL which is what you are finding in the auto wreckers. It is throw-together applications such as this that cause problems for people and I would not recommend putting your ignition system together in such a manner.....
