Mopar electronic ignition
What is the resistance of the high tension coil wire? I always start out by checking "right at" the coil tower..........use a grounded clip screwdriver etc and crank engine. Should have a nice hot spark at least 3/8" long and typically 1/2" (about 9--13mm)
Next check the coil wire resistance. The old school rule of thumb for resistance wires used to be 1000 ohms per foot. They are almost always less
Then inspect or even replace the rotor. They can spark "punch through" the insulation,.........inspect carefull inside where the shaft fits for black, holes, damage.
obviously both the cap and rotor should be clean and dry
