Like any complex system, it is the sum of many parts that keeps your vehicle running without a hitch. When one part of the system is down, it can affect various parts of your vehicle. Whether your vehicle is a Acura, Audi, BMW, Buick, or something else, the signs of a failing or broken alternator are universal. Here are five signs that you may need to come in for alternator testing, repair, and/or replacement:
Your battery light is on –Â Our dashboard lights serve as surefire indicators that something is wrong. If your battery or check engine light turns on while driving, there may be a problem with your vehicle’s alternator, its battery, or both. If your car does not have a battery light, it will likely have an ALT (alternator) or GEN (generator) light that will turn on when something is wrong. If this happens, pay particular attention to your vehicle’s electronic components. For example, if you are driving in San Marcos, CA at night with your headlights on, and then you decide to turn your radio on but it does not work, this is a strong indicator that there is an issue with your alternator.Â
Your vehicle’s electronic accessories have slowed down – One of the most common signs of a failing alternator is dim or flickering headlights. Similarly, your vehicle’s windows may roll up and down more slowly than usual, or your backup camera may have glitches. Of course, it is possible that there is something wrong with the accessory itself, but if you are experiencing more than one of these issues simultaneously, there is a high possibility the problem is the alternator.
Your vehicle’s serpentine belt is loose – If you are experiencing any of the above signs, you may want to check your vehicle’s serpentine belt (if you are unsure about this, our technicians at Escondido Autopros- Auto Repair & Hybrid Repair can take a look for you). Because the serpentine belt helps power the alternator, if this belt is loose, it will affect your alternator’s performance.Â
You hear strange noises coming from your vehicle – Negative sensory cues are a sure indicator something is wrong with your vehicle. If you are hearing grinding or whining noises, this could mean one of the parts inside the alternator is worn out or broken.
