Do I Have A Faulty Alternator?

A car's alternator is one of the most underrated devices in the vehicle because the battery takes most of its credit. Most people imagine that because the car's battery helps ignite the vehicle, it is one of the most crucial elements of the car's electric system. However, they couldn't be further from the truth because an alternator immensely powers all the vehicle's electrical system apart from charging the car battery while you drive. There is, therefore, danger in driving a vehicle with a faulty alternator because it will leave you stranded over a flat battery or dim your lights while you drive at night. If you are unsure about the state of your car's alternator, the following are telltale signs of a faulty alternator:

Weak battery.

The primary role of an alternator is to recharge the car's battery while driving. It converts mechanical energy from the engine's rotating pulleys into electrical energy that charges the battery. A faulty alternator would therefore mean that it will not charge your car battery optimally. A regular flat battery might indicate that your vehicle has a faulty alternator and needs attention.

Malfunctioning electrical accessories.

The vehicle's electrical devices will begin to lag with a faulty alternator. You will therefore begin noticing issues like lagging windshield wipers, headlight dimming, and malfunctioning power seat adjustments. Checking on a mechanic should be your number one priority because electrical malfunction like dimming lights is dangerous and could lead to accidents.

Battery Light On the dashboard.

Dashboard light is the best On-Board Diagnostics symptom that indicates an underlying problem with your vehicle. The vehicle's battery-shaped light, ALT, or GEN, will pop in your dashboard when the faulty alternator is faulty. The warning lights are indicators of trouble in your vehicle's electrical system, and neglecting them is a prerequisite for further severe mechanical trouble.

It is always good to check on the mechanic whenever you feel that you are driving a vehicle that is not functioning optimally. A car's faulty alternator will sap away the joy of your weekend road trips with friends and family unless you take the necessary diagnostics and repair.
