click all that apply. ______________ is a key cause in
alternator failure.

□ a worn belt tensioner

□ a misadjusted loose or worn belt

□ a bad or discharged battery

□ bad gas

Explanation:

• A worn belt tensioner can affect the alternator's operation as it controls belt tension, leading to failure.
• A misadjusted, loose, or worn belt can cause the alternator to not function properly (e.g., slip, not spin enough) and fail.
• A bad or discharged battery can put stress on the alternator (e.g., overworking it to charge a bad battery) and cause failure.
• Bad gas affects the engine's fuel system, not the alternator, so it's not a cause of alternator failure.

Answer:

A. a worn belt tensioner, B. a misadjusted loose or worn belt, C. a bad or discharged battery
