Auto Electrical Diagnostics: Solving Common Electrical Problems in Vehicles
Hello readers! Today, we will be taking a deep dive into the complex and fascinating world of auto electrical diagnostics. At one point or another, we've all experienced issues with our vehicle's electrical system, which can be quite vexing and mysterious. But don't worry, in this blog, we're going to explore some common electrical problems, identify their root causes, and offer practical solutions.
The Mysterious Case of the Dead Battery
We all have been there, you hop into your car, put the key in, and nothing. The first thing that you must do in this case is to check the terminals of the battery. You have to see whether the terminals are corroding or could be the case of a loose nut. The corrosion might disrupt the flow of electricity. So, make sure you clean them and secure them. If that doesn’t work out, then your battery could be at the end of its life and there is only one solution to that; NEW BATTERY!
Refusing to Start
Nothing is more frustrating than putting the key in the ignition and hearing silence in return. Begin the diagnostic by checking the voltage of your battery using a multimeter. If the voltage is low, it is indicative of the fact that the vehicle either requires a replacement or a jump start. If the voltage reading is fine then move towards the solenoid. A faulty solenoid can prevent the starter motor from engaging. Replace it and your engine should roar back to life in no time.
Do you feel as if your headlights have been looking a bit dim? It could be possible that the bulbs inside the headlights might be near the end of their lifespan. Replacing them with new ones will make you feel as if you got brand new headlights in your vehicle. If the bulbs are fine then there is a possibility that the alternator is not functioning properly. It is an electrical generator that converts mechanical energy to electrical energy. The purpose of the alternator is to charge the battery which powers the system as the engine runs. The alternator could not be providing enough power for the lights to function. Hence, the dimness of the lights. If that is the case, then it’s time for a trip to the mechanic.
Sometimes, you leave your car parked only to find out that the battery has drained out completely. This happens due to a parasitic electrical drain. Even with the car switched off some part of the vehicle could be drawing power from the battery. This is because that part is malfunctioning. Finding which part could be causing this is no less than detective work. But, once you’re able to pinpoint the cause the solution is quite simple. Replace or repair the component and the problem of the draining power will disappear with it.
Misbehaving Power Windows
Power windows are one of the blessings a vehicle could have. That is until they stop working the way they should work. First, check the window buttons and make sure they are functioning. If the problem doesn’t lie there the window could be malfunctioning. The connection that causes it to function could be stuck with dirt or the wires have loosened with time. Cleaning the connections or replacing them with new ones should do the trick. If the problem still persists, the motor in the window might be waiting for a check-up.
The Silent Radio
Music and the radio are your best partners when you’re out on a long ride. Has it ever happened that you turned on your radio and you have greeted by silence? The solution is simple, start by checking the fuse of the radio. If it appears as if the fuse has been blown then replace it and you’ll get your tunes back immediately. If that doesn’t help in fixing the issue, check the antenna connection. A damaged or loose antenna cable will cause the radio signal to get disrupted, hence the silence. Tighten the connection and your radio should be up and back running in no time.
Check Engine Light
The biggest nightmare any vehicle owner could face is seeing the check engine light. The engine is the most essential part of any vehicle. Without which the vehicle is non-functional. This could occur due to various issues. It definitely includes any problems with the engine for sure. But, often is caused by the problems in the exhaust of the car. An electrical fault in the vehicle can cause it as well. The ‘Check Engine’ light could get illuminated by a damaged or loose gas cap. Sometimes the vehicle might not be able to identify which of the sensors are faulty.
However, since it still wants the owner to know that there might be a potential problem in the vehicle, it turns the check engine light on. With the help of a diagnostic scan tool, you can identify the specific trouble code. This is useful even if the engine control unit is or could be malfunctioning. This will aid in narrowing down where the problem is and allow you to take the necessary steps to fix the issue.
