I would use a test probe with the 12volt bulb.Put the groung clip on a good ground and place the tip on the other side on the coil.See if light flashes when cranking the engine.If it flashes the module is working.If it stays on all the time the module is not turning on and off.If there is no light the coil is open circuit. Some of the older mopars used a ballast resister in the coil circuit not sure what year the stoped using them.If the resister opens there is no spark. Good Luck Mike |
