does 88 YJ have an external ballast resistor??>

I've tried search and can't find anything definitive.

There has not been one on the Jeep since I've owned it, 8 yrs, and it has run fine. Now it will not run.

My crappy Haynes manual shows a cartoon drawing of the coil with a ballast resistor attached to the coil bracket(my bracket has the provsions for the resistor).

I called several parts stores and their computers do not show a ballast resistor for 88 YJ's.

I tested the voltage at the battery, 13.1V, and at the coil with the ignition in the "ON" position, it shows 6.2V.

Does this mean I do not need an external resistor?

Thanks for any info, as I soon as I know I am going to run to the parts store and get a new coil and/or a resistor depending on what answers you guys give me.

That's not a ballast resistor, it's a type of filter to help stop electronic noise in your radio. I believe they call it a condensor.

Your voltage at the coil is slightly low, should be around 8.7v with the key in run. There is a resistor wire in the coil harness that drops the battery voltage to the coil. So, the answer is "no", because you already have one.
