Thread: Ignition coils

Tweet

I recently purchased a MSD blaster 2 coil for my car and upon reading another website that sells coils they mention that I may need a ballest resistor.

Their exact quote is, "the blaster 2 can be used on all 4,6, and 8-cylinder engines with or without an MSD Ignition. This coil does not include and does not need a ballast resistor because when you are using an MSD Ignition Control, the ignition is responsible for deliveringthe voltage to the coil."

So my question is do i need one or not? Actually I'm sure I already have one on my Charger. Will have to check. Plus, will I need their resistor or will my exsisting one work?

Additionally they claimed this also, "ballast resistor must be placed in-line with the positive terminal of the coil when used with stock points style ignitions and Mallory ignitions. Since I don't have stock points (converted over to an electronic ignition) or a Mallory ignition will i have to do this?

That is all. Please respond ASAP since I plan on working on it this evening.

BTW, I'm not using a MSD ignition control.

No, you do not need the ballast resister if you are using an electronic ignition (no points).

Thanks, that solves that issue.

Now I can go to it.

I know that the Mopar conversion kit comes with a ballast resister but i'm not sure that the conversion from points to electric was indeed a Mopar conversion kit.

Should I assume that if it was not then I shouldn't need it still?
