What’s Wrong with My Alternator - Vancouver Auto Repair

So how much do you know about your alternator? You’ve probably heard of this important part of your vehicle, but do you know what it actually does? Your alternator works with the battery to maintain power for your vehicle’s electrical system. When the alternator goes bad, you will notice a difference.

Many times, people mistakenly think their battery is bad when they have electrical issues. But often, it’s the alternator that is going bad. If you start to notice any signs of trouble, the best thing to do is bring your vehicle into our Vancouver auto repair shop to get your vehicle tested. Our diagnostic tools will tell us if it’s your battery or your alternator. Once we know what’s causing the problems, then we’ll get it fixed.

Signs of a Bad Alternator

There are several warning signs that your alternator is bad or starting to go bad. Here’s what to look for.

Flickering or Weak Headlights – if you notice that your headlights are not shining as bright as they normally do, or if they start to flicker, this could be your alternator. For example, if you’re driving at night and you turn your radio on and the headlights start flickering this is a sure sign something is bad with the alternator. If it has trouble powering two electrical components at the same time, it’s probably time for a replacement.

Dying or Weak Battery – car batteries get old and obviously they wear out. So, a battery can go bad without the alternator having anything to do with it. However, the alternator also helps your battery hold its power, so if your battery is having a hard time holding a full charge, it could be because your alternator is failing and not your battery.

Car Has Trouble Starting – if your car won’t start easily, this is another sign your alternator is bad. This is a tough one, because your alternator, battery, and starter all have to function properly for your car to start. So, if it won’t start right up then it could be any or all of these parts. The only way to know for sure is to get it tested.

Weird Sounds – your alternator can also make weird sounds when it’s worn out. It has several moving parts, so if something breaks or quits working right it might make an unusual grinding sound, which could be coming from a bad bearing. Additionally, if the voltage regulator is off it could cause a whining sound because the alternator is charging at a higher level than needed.

Electrical Issues – if you notice any kind of issues with anything electrical it could be your alternator. For example, if your power windows, heated seats, stereo system, power locks, or your wipers, don’t work right or can’t get enough power, then your alternator is likely the reason.
