Check Used Car Electrical, Car care tips today from gNewscar – For those of you who might have plans to buy a used car the first time you have to check is the electrical of the vehicle, this is very important so that later you do not panic when the vehicle is in trouble with electricity.
What Are Component Check Used Car Electrical ?
Because the car you are going to buy is not a new car anymore, it is natural that there has been a decline in performance. The reason is none other than because some components of the source of electricity are quite old. Examples such as batteries, alternators, and all kinds of cables.
Electrical which starts to be problematic is marked by the instability of some components when used. For example, headlights, car air conditioners, or wipers that have differences in performance when gassed and not gassed. Now, to ensure the performance of the electrical system, let’s look at a few components:
5 Components Car Electrical That Must Be Checked
Car Alternator
This tool serves to supply electricity into the battery. If the alternator is not working properly, the battery is lacking electricity. The battery becomes overdrawn and needs to be electrocuted again.
To see the condition of the alternator, we can simply look at the battery icon indicator on the dashboard instrument panel. If the indicator stays on, the alternator has a problem. The next way is by attaching the LED light to the lighter connector. If the LED is red, it means the alternator is not good and if it is blue, it means that the condition is good.
The most accurate way of measuring is with a voltmeter. Turn on the car engine and turn on all equipment that needs electric current such as wipers, headlamps, fog lamps, audio systems, air conditioners, etc. Measure the voltage on the battery, if the result is 12.5-13 it means that the alternator is in good condition. If under 12, it means that the alternator has a problem.
Negative Cable
Cars that are over 7 years old, usually the body has lost power between electricity. All that happens because of a chemical reaction with oxygen and water such as corrosion or crusty dust or something else.
For older cars, it is recommended to use a grounding kit. The goal, to add negative cables that are more evenly distributed throughout the car body.
Car Battery
A problematic battery will reduce the ability to supply electricity to a number of components such as lights, wipers, air conditioners, audio systems, etc. Characteristics, these components work unstable.
Aki generally have a service life of between 2-4 years. A good car battery has a voltage between 12-13 volts. To measure it use a voltmeter. If the result is below 12 volts, the lamp will dim and other parts also lose their optimal function.

Relay kit
The function of the relay kit is to get good quality electricity on certain parts that need it. For example, on audio systems. Or the halogen lights on adventure cars. Usually, this relay kit is installed on cars that have been modified.
It is important to check this relay kit to make sure its performance is still optimal. Because, if you have experienced problems, then in addition to its function being not optimal, it can also cause a short circuit risk on the vehicle.
Cable Connection
We must check whether there are cable connections on the car. Because, this kind of connection should be avoided. Damaged or broken cable, you should replace it with a new cable. In addition to ensuring good delivery power, the new cable will be relatively safe from being shorted.
A good cable is a cable in one piece. Or if you have to make a connection, use the connection part. It can also by soldering the cable and then covering it with insulation / tape that is tight.
Checking the electricity of the car is not only a matter of ensuring good condition, but also a matter of safety from other hazards such as short circuit and fire. For this reason, involve experts who are aware of this issue.
