I am not the expert, only an owner trying to keep my cart going, but it appears the igniter is connected to the ignition coil and sends a signal to it for spark for the spark plug. It is located very near the drain plug for changing oil. Anyway my cart is now running and it appears the problem was the ignigter. It appears I was being taken by the person who charged me for a coil that was not replaced nor defective. I will be discussing that with him on Monday. Thanks again to all who helped. This is a great forum and I enjoy just reading the posts.
