What are the symptoms of a damaged car alternator?
2 Answers
Automobile alternator damage symptoms include dimming of car lights or dashboard lights; damage to the battery or accumulator. The following are specific details about car alternators: 1. Working principle: When the external circuit energizes the excitation winding through the brushes, a magnetic field is generated, and the electrodes are magnetized into N and S poles. 2. Maintenance: It is necessary to frequently clean the accumulated dirt and dust on the alternator's surface to maintain cleanliness and good ventilation. Regularly check the tightness of all fasteners related to the alternator and promptly tighten all screws. 3. Function: The car alternator is the main power source of the vehicle, whose role is to supply power to all electrical equipment except the starter when the engine is running normally, while also charging the battery.
My old car's alternator broke down last year with very obvious symptoms. One morning on my way to work, the little battery light on the dashboard suddenly came on. At first I thought it was a false alarm, but after driving for half an hour, the headlights got progressively dimmer, like fireflies, and the radio started cutting out. The worst part was when it completely failed to start after work, costing me over 200 bucks for a tow truck. The mechanic said the alternator bearing had shattered, preventing charging and draining the battery dead. If you notice abnormalities like slow power window operation or weakened AC airflow, nine times out of ten it's alternator trouble. Get it fixed early, otherwise suddenly breaking down on the highway could be life-threatening.
