To protect the ignition system against high over voltages upon removal of a load in the high voltage circuit, represented by the spark gap of a spark plug, and a distribution gap of a distributor, an electrically conductive terminal element, such as a flag, a spring biased tab, or a push spring which is connectible to ground or chassis is so located that, when the spark plug cable terminals are connected, the insulator of the spark plug cable terminal will be interposed between the flag and the high voltage terminal which is to be protected. The flag may be permanently spaced from the high voltage terminal-for example to prevent low voltage dc flow, when applied to the high voltage terminal of the coil; maybe spring biased to fit against a normally isolated terminal for example a spark plug distributor terminal; or maybe in form of a compression spring element which is pushed from a position adjacent a grounding cap into a position remote therefrom and where the normal plug insulator is attached by the high voltage pin terminal connection on a spark plug.
