If you’re experiencing electrical issues, it’s important that you find and fix the problem as quickly as possible. Your electrical system runs everything from your starter to your headlights, so it’s crucial that it’s in good shape. Read our electrical repair tips to learn how you can get your vehicle back up and running as soon as possible.

Start by Inspecting the Battery

When it comes to vehicle electrical issues, a dead or weak battery is often the cause. If you’re struggling to start your car, check the battery. Look for any corrosion on the terminals, which you can clean with a wire brush and a mixture of baking soda and water. This should restore proper contact to the terminals.

Check for These Common Problems

Blown Fuses

A blown fuse can make many of your car’s electrical components stop working, including your power windows, lights, and radio. Find your fuse box (often under the hood or dashboard) and look for fuses with a broken metal strip inside. This indicates the fuse is blown and needs to be replaced.

Alternator Issues

If your car won’t start but you know your battery is working, the problem may be the alternator. When your alternator fails, you may notice dim lights, failures of electrical components, or a dead battery. The best way to check your alternator is to use a multimeter — if it reads below 13.5-14.5 volts when the engine is running, it may need to be replaced.

Damaged or Loose Wiring

Over time, wires can loosen, corrode, or fray. Check your vehicle’s wiring, especially around the battery, fuse box, and alternator. Use electrical tape to cover frays on any damaged wire you find, or have them replaced by a professional if the damage looks extensive.

Get a Professional Diagnostic Test

There’s no need to deal with your electrical issues all on your own. Contact a reputable auto shop to get a professional diagnosis from trained technicians. They can check your vehicle for error codes and use their expertise and knowledge to find the root of the problem with your car, as well as provide repairs so you can get back to driving smoothly.
