When it comes to our cars, we take them for granted. We expect them to start every time we turn the key, and we don’t think twice about the battery that keeps everything running. But what happens if that battery starts to lose power? Well, in some cases, a faulty ignition switch can be to blame. This switch is responsible for turning the engine on, and if it’s defective, it can cause the battery to drain even if the car is off. This is something you want to keep an eye out for if you have a car with a battery that’s not holding its charge as well as it used to. If you notice your battery starting to lose power quickly, make an appointment with your mechanic to check out the ignition switch.
What is a Faulty Ignition Switch and how does it drain a car battery?
A faulty ignition switch can drain a car battery, and if not fixed, it can result in a car not starting. The problem is caused when the contact points that are supposed to activate the coil inside the ignition module don’t work. This causes the car to run on battery power instead of gasoline, which can wear down the battery over time. When this happens, you may experience problems starting your car or losing power while driving. In worst case scenarios, a faulty ignition switch could even result in a car explosion.
How to test if your ignition switch is defective
If your car’s battery is drained even when the ignition switch is turned off, there may be a problem with your ignition switch. Here are four ways to test if your ignition switch is defective: 1) Use a voltmeter to check the voltage at the battery terminals while the car is running. If the voltage is low (below 12 volts), there may be a problem with your ignition switch. 2) Check for continuity between the red and black wire of your car’s electrical system. A broken or shorted wire will cause no voltage to be seen at the battery terminals, indicating a faulty ignition switch. 3) Test for movement of your car’s key fob by placing it close to the keyless entry sensor on the door. If the sensor detects movement, there may be a problem with your ignition switch. 4) Remove the steering wheel
If any of these tests reveals a fault with your ignition switch, you’ll need to replace it.
How to replace an ignition switch on a car
If your car’s ignition switch is not working properly, it may be draining your battery. The ignition switch regulates the flow of electricity to the starter motor. When it fails, the electrical current flowing to the starter motor can be too high, which can cause the battery to drain quickly. If your car has a removable headlight cover, you can check the status of your ignition switch by removing the cover and inspecting the electronics module near the keypad. If your switch is broken or defective, it will need to be replaced. Replacement costs vary depending on make and model, but typically run around $100.
Conclusion
If you’re having trouble starting your car, are getting warning lights when you turn the key in the ignition, or hear a clicking noise when you try to start your car, it might be time to have a mechanic look at your ignition switch. A faulty ignition switch can cause all of these problems and more and is usually fixable by a mechanic. If you’re unable to get your car started, don’t hesitate to call a tow truck and have them take it in for service.
