DDifficulty 3/5

In a conventional charging system, the warning lamp works during its initial check and goes out when the engine starts. If it stays off with the engine running, what does it normally indicate?

Correct answer

Normal charging-system operation, with no fault warning.

Normal charging-system operation, with no fault detected by that lamp. It does not by itself prove that every electrical component is perfect. If it stays on or comes on while driving, follow the manufacturer’s instructions: the alternator, regulator or wiring may be faulty. A defective lamp might not warn of a fault, so this scenario specifies a working lamp.
