How Does an Alternator Work?
A vehicle's alternator is part of its automotive charging system, along with the battery and the voltage regulator. The alternator and battery work together to generate power for the electrical components of your vehicle, such as the air conditioning system and headlights. These components are essential for a comfortable drive on the roads of Bradenton. The alternator gets its name from the alternating current (AC) it produces.
The alternator is located near the front of the engine and is driven by the crankshaft, which converts the up-and-down movement of the pistons into circular movement. Most alternators are bolted to a specific part of the engine for this purpose. The electric current generated by the alternator is passed on to the vehicle's battery, providing the energy or voltage needed to run the vehicle's electric systems.
Your vehicle's alternator has vents on both the front and back sides to aid in heat dissipation. The back of the alternator has several terminals or connecting points in the electrical circuit. These terminals sense battery voltage, turn the voltage regulator on, close the circuit to the warning lamp, and serve as a full-field bypass for the regulator. Damage to any of these terminals can affect the alternator and, consequently, the entire vehicle.
Several signs may indicate a failing alternator. If you notice any of these signs, bring your car to Suncoast Auto Repair Inc in Bradenton today.
How Do I Know If My Alternator Needs to Be Replaced?
Like any complex system, a vehicle's proper functioning depends on many parts working together. When one part fails, it can affect various parts of your vehicle. Whether you drive a Chrysler, Toyota, Honda, Nissan, or another model, signs of a failing or broken alternator are similar. Here are five signs that you may need alternator testing, repair, and/or replacement:
- Your battery light is on: Dashboard lights are reliable indicators of problems. If your battery or check engine light turns on while driving, there may be an issue with your vehicle's alternator, battery, or both. If your car doesn’t have a battery light, it may have an ALT (alternator) or GEN (generator) light that turns on when there’s a problem. Pay attention to your vehicle's electronic components. For example, if you are driving in Palmetto, FL at night with your headlights on and then notice that your radio doesn’t work, this could be a sign of an alternator issue.
- Your vehicle’s electronic accessories have slowed down: Common signs of a failing alternator include dim or flickering headlights. Similarly, windows may roll up and down more slowly, or the backup camera may have glitches. While these issues might be due to the accessories themselves, experiencing multiple problems simultaneously suggests the alternator might be the cause.
- Your vehicle’s serpentine belt is loose: If you notice any of the above signs, check your vehicle’s serpentine belt (our technicians at Suncoast Auto Repair Inc can assist with this if needed). Since the serpentine belt powers the alternator, a loose belt can affect the alternator's performance.
- You hear strange noises coming from your vehicle: Unusual noises, such as grinding or whining, can indicate that a part inside the alternator is worn out or broken.
