In the crane's electrical system, which component charges the battery?

• A. Alternator
• B. Battery
• C. Starter
• D. Fuse

Answer: (A)

The component that charges the battery is the alternator. Driven by the engine, the alternator converts mechanical energy into electrical energy and supplies DC power at the proper charging voltage to the battery while the engine runs. This keeps the battery topped up and powers the crane’s electrical loads during operation. The battery itself stores energy and can supply power when the engine isn’t running or when demand spikes beyond what the alternator provides. The starter uses battery power to crank the engine, so it does not charge the battery. A fuse protects circuits by interrupting excessive current, not charging the battery.
