Two technicians are discussing waste spark type ignition systems. Technician A says that half of the spark plugs in the system fire in reversed polarity [from the ground electrode to the center electrode]. Technician B says that the two spark plugs are connected in series with the coil. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

In waste spark ignition systems, half of the spark plugs indeed fire in reversed polarity, meaning from the ground electrode to the center electrode, as stated by Technician A. Additionally, Technician B is correct in saying that the two spark plugs are connected in series with the coil. This configuration allows for one spark plug to fire in a forward direction (center to ground electrode) while the other fires in reverse (ground to center electrode) during each ignition cycle.
