1. An ignition analyzing apparatus for analyzing the functioning of capacitor discharge ignition systems comprising an electronic pulse source means adapted to establish a plurality of time spaced pulses, a selection means having a releasable connecting means for selectively connecting the output of said electronic pulse source means to an ignition system to provide timed trigger of said ignition system, and a portable spark gap means constructed to create a load corresponding to the load driven from the ignition system and adapted to be connected to said capacitor discharge ignition system and driven from the output of said capacitor discharge ignition system to produce a visual display of the operation, said pulse source means includes a first electronic oscillating circuit establishing a plurality of output pulses, and a switching means is connected to said oscillating circuit and controlled thereby to establish a time delayed signal for a predetermined portion of each cycle.
