If you own a car, you will probably understand that you need to check the oil level, change the spark plugs and clean the air filter to keep your vehicle running. However, have you given a thought about your car's electrical systems? Overlooking this vital part of your automobile is easy. However, if you do not maintain your car's electrical system, it is likely you will have car trouble in the future. Below is a guide to 4 things you should consider when making sure your vehicle's electrics are in good shape.


Your car's battery is at the heart of the electrical system. The battery stores the power needed to start the engine and to operate the lights and over electrical equipment. You should periodically inspect the battery for signs of damage. Start by unscrewing the bolts which hold it in place and carefully lifting it from the housing. Examine the battery to make sure it is not leaking battery acid and that the terminals and connectors are not corroded. If there is any corrosion, this should be removed using a brush and a spoonful of baking soda mixed with hot water. If you have any concerns about the condition or performance of your battery, you should take it to be inspected by an auto mechanic.


The alternator is the part of your car's electrical system which is responsible for charging the battery using energy generated as the wheels turn. You should use a voltmeter to check that the alternator is working properly. Simply attach the voltmeter to the battery and take a measurement. You should then start the engine and monitor the voltmeter. If the reading on the voltmeter increases when the engine starts, this means that the alternator is charging the battery. If you hear a high-pitched squealing sound when the engine is running, this could be a sign that the alternator is faulty.


Finally, it is important that the sensors on your vehicle are working properly. When electrical sensors fail, they can send false signals to your car's onboard computer, triggering warning lights. You can test the sensors by using a multimeter to test the circuits which each sensor is connected to. When you attach the multimeter to a circuit, you should see a reading. If the multimeter fails to detect a reading, it is likely that the sensor has failed.

If you have any concerns about the condition of your car's battery or other electrical systems, you should contact an auto mechanic today.
