    Switches for Twin Plug Ignition

    Hi, what purpose do the switches serve? Do they switch from one coil to another if one craps out, like a magneto switch on a aircraft engine? Thanks.

    Great for sorting out misfires.

    Can be a real nightmare with 12 plugs.

    Switch off one circuit and then the other to see where the problems lies.
