ABSTRACT:
A metal plate is mounted on the engine head in electrical conductive relation. An electrode test unit is mounted on the metal plate, having a pair of electrodes forming a spark gap, one contacting the plate and the others adapted for securement thereto of the spark plug wire. Each spark plug can be removed individually from the engine and mounted in the plate in electrical conductivity therewith. The spark wire can then be selectively secured to the electrode unit or the spark plug, and the operator's hands are free to turn the engine. The plate is left mounted on the engine permanently.
