agree with the above post. worst case scenario is the ezl unit also.

check the coil where it mounts to the body. any "white" you see on the coil body where there transformer core meets the bracket, that's leaking voltage, also. very common. any extra gap the spark has to jump means more amps from the coil. more amps means a tired coil and the shortest path to ground. that's why the white on the coil and the corona you see around the wires. good luck, chuck.
