Systems to Test When Your Car is Having Electrical Problems
Start With The Battery
Look over the battery itself. Are the connections rusty or damaged looking? Do the cables look worn out? These issues can contribute to a battery issue if you’ve already gone through this experience recently. Typically, your battery is located under the hood of your car, but some models have the battery installed in the vehicle’s trunk. If you don’t know where to look, be sure to consult your owner’s manual for all information related to your battery.

Next, Test the Alternator
- Turn your car on and let it run. While it is running, unplug the positive connection from the battery. If the car stops, then the alternator is not working properly. The positive connection is red, while the negative connection is black.
- Monitor the dashboard lights and note if they fade in and out or flicker. This is another clear indicator of alternator issues.
Note: Do NOT attempt to test the alternator by unplugging the negative cable while the vehicle is running as this will result in damage to your vehicle’s electrical system.
There may be a few signs prior to failure that are worth noting. You will likely hear a growling sound, smell burning rubber inside of your car, or you may notice lights dim or brighten significantly. If you suspect your alternator is failing, check out our Car Brake Services page for more information.
Last, Check The Starter
Your car starter has a really important job to perform – frequently. The battery sends a burst of energy to the start which uses this energy to turn the engine over and get it car started. If you put the key in the ignition, but only hear a click when you turn the key, you’ve got a problem with your starter. This sound is very similar to the sound the car will make when the battery is dead, so if you’ve already confirmed your battery is not faulty, you can safely assume this sound is related to the starter.
