The daylight hours are getting shorter now and we depend on our lights more and more. I have noticed people driving around with one headlight out or brake light and one can only assume a turn signal (though some people just don’t bother to use them for some strange reason!). It is a good idea to test your lights! You can have someone assist you, ask us to check or check them out yourself by pulling up to a building and shining your lights or even do it in your garage. Seeing well while driving is very important, and it is also important that others see you!
If your headlights seem yellowed, we can fix that! Just contact us and we’ll tell you how we do this (no, it isn’t magic!).
When Your Lights Go Dim
Your vehicle’s alternator keeps the battery charged. The alternator replaced the generator of the past. If your car fails to start as quickly as it used to (hard or slow cranking) or your lights seem dimmer it could be a sign that your alternator needs to be replaced. If you are used to dashboard lights telling you of a problem and you didn’t see the “alt,” “bat,” or “gen” light come on to alert you, keep in mind that the alternator is responsible for those dashboard lights! If it isn’t working then the lights will not illuminate.
When an alternator fails it usually does so in stages so pay attention when things start functioning abnormally. The signs are often subtle such as dimmer lights. You may be using all the bells and whistles at once such as the television, wipers, air conditioning, and the navigation system and they seem sluggish. When you stop using one or more of the functions the remaining ones work better. The dashboard lights may start flickering.
When you take your vehicle to your car care provider they will:
- Perform a “load test” to check the voltage readings (measure the voltage at the alternator connector and the battery)
- Check the belts to determine if they are old and cracked or slipping
- Listen as an experienced mechanic can tell from clanging or rattling noise that something is not as it should be
Alternators work long and hard for us but occasionally even the best can fail. The battery will still run many miles on reserve power so this usually saves you from being towed in. As always, if things aren’t working as well as they normally do it is best to have it checked out before it becomes a serious problem. This always saves you time and money!
