Question: 1 / 400

The primary purpose of the ignition system is to:

Charge the battery

The correct answer is not A. The primary purpose of the ignition system is to provide a spark at the spark plug. This spark ignites the air-fuel mixture in the combustion chamber of the engine, causing combustion and ultimately starting the engine. Option A, charging the battery, is not the primary purpose of the ignition system. Option C, regulating fuel mixture, is controlled by the carburetor or fuel injection system, not the ignition system. Option D, starting the engine, is a result of the ignition system providing the spark necessary for combustion.
