Abstract A device for alternate use as an emergency replacement coil and condenser unit or as a tester of automobile spark plugs. The unit is in the form of an enclosed housing in which an automobile ignition coil and condenser are mounted in parallel to the low voltage coil terminals. A momentary normally closed push button switch is mounted in a housing wall and connected in series with one of a pair of low tension lead wires extending from the housing, with the lead wires connected in parallel to the coil and condenser. The high tension outlet connection of the coil is mounted adjacent a hole in the housing for insertion of the coil terminal of cable of an engine leading to the high tension connection of the distributor cap, when the low tension lead wires are connected across the low tension terminals of a defective engine ignition coil to substitute the device for the engine coil. Alternately, the low tension leads of the device may be connected directly to a battery and a spark plug connected by a portable cable and a ground connection cable to the device, with operation of the momentary control switch causing a spark across the spark points of a normal spark plug.
A device which alternately serves for emergency use as a replacement engine ignition coil or as a spark plug tester, comprising a housing enclosing a condensor and an ignition coil, with a sleeve extending through the housing located adjacent the high tension terminal of the said ignition coil, with a first and a second flexible insulated wire each externally attached to an individual clamp and each wire extending into the housing and connected to both a first low tension lead of the said ignition coil and to a first terminal of the said condenser, together with a third flexible insulated wire externally attached to a clamp and extending into the housing and connected to a first terminal of a normally closed momentary contact switch mounted in a housing wall, said switch connected through its second terminal to the second terminals respectively of both the coil and condenser, together with a length of flexible high tension insulated ignition cable, one end of which is fastened to a sleeve of a size to fit over a body of a spark plug and the other end of which is shaped to attach to the conductor of the coil when fitted through the sleeve in the housing, so that when a sparkplug is attached in the sleeve of the ignition cable, the conductor of the ignition wire is in contact with the terminal of the sparkplug.
