gremlin's in my spark!!!

Connect a spark plug to your coil wire and make sure it is grounded. Have the engine cranked over. If you have spark it could be your rotor. If not check for power to the coil . Then check if the negative side is being switched by putting a test light accross the two small terminals. If the light comes on you do have a ground but it is the shutting off of the ground that gives you the spark.
