  9. Left ignition coil not sparking CX500

    Technical Help Forum
    Hello, I just picked up a 1980 CX500 and the left coil wont spark. The right side sparks when it is wired normally. When I swap the pink and yellow cables, the left side still doesnt spark. Which leads me to believe that its just the ignition coil. However, These are brand new. I checked the...
