It’s mind-blowing to think about vehicles a century ago as compared to now. Who would’ve thought that our cars, trucks and SUVs would be driven by computers? Who envisioned the electrical components found in vehicles today? Even the classic cars of the ‘50s, ‘60s and ‘70s don’t have to complex electrical systems that drive 21st-century automotive technology and, you guessed it, complex means more things can go wrong. Heath’s Auto Repair lists common automobile electrical trouble.
Battery System
Your vehicle cannot run without electrical power and the battery system provides and disseminates that electricity. Starting with the battery, signs it’s at the end of its lifespan include
- Dimmer interior and exterior lights
- Difficulty starting the vehicle initially and after being driven
- Complete engine start failure (the engine won’t turn over at all)
If there is still some charge left in the battery, you can start your engine via a jumpstart. If your vehicle’s battery is gone for good, you won’t be able to start it with jumper cables nor will it hold a charge.
Other issues related to the battery include a bad alternator, worn cables or a failing solenoid or starter. The alternator powers electrical accessories, the ignition and the starter. As with a dying car battery, you’ll notice dimmer headlights while you drive if your alternator is going bad. If your car refuses to turn over when you turn the ignition key, it could be your alternator but it might also be your starter.
Corroded battery cables are death to your battery. The corrosion is passed onto the battery terminals which, in turn, corrode them. The first thing you should do if your car won’t start is to pop the hood and check the battery cables. Are they corroded? Are they loose? Either could be the reason why your vehicle won’t start. If you aren’t comfortable checking these things out, call for professional help.
Blown Fuses
As with your home, your car’s electrical system is attached to fuses. If any of the fuses blow, the related electrical component will lose power. This is an easy DIY fix, so pull out your owner’s manual, identify the blown fuse, purchase it from an auto supply store and replace it. Spark plugs also affect your vehicle’s electrical system, and dirty, loose or old ones can cause lurching and stalls.
