Find someone you like but can do without as a friend. Have them hold the wire and crank it over. If it knocks them on their a$$ then you know that you have a cood coil. If they still want to be your friend then the coil is bad....

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.
