AN IGNITION ANALYZER FOR INTERNAL-COMBUSTION ENGINES 470254

WITH this portable electronic ignition analyzer, malfunctioning of the ignition system can be detected by observing primary-voltage wave forms shown on the screen.
Some of the conditions which can be detected and identified are a short in the high-tension circuit, insufficient voltage to break down the spark-plug gap, an open-circuit primary due to insulated contact points or a broken primary connection, and excessive arcing at the breaker points.
The instrument's dependability and utility have been proved for aircraft engines. With modifications it could be used with other types.
