Ballast Resistor

Where to look for a potential troublemaker; a bad ballast resistor.

Most Chrysler engines use a ballast resistor. If it burns out the engine will start as you crank it, then stall the instant you let go of the ignition switch. Also, the connectors can "fall off" and kill the engine. Better check yours.

Note: Older spark modules used 5 pins; newer ones use only 4. Both work the same--I have one of each on my boat. The fifth pin and the other circuit on the ballast resistor was put there in an exercise in over-engineering by Chrysler, who were famous for such antics
