How to Fix Car Ignition Switch Problems There are many reasons why your car may be running and starting but the ignition fails to turn on the spark plugs. Some are easy and cheap to fix, while others require special tools and assistance from a mechanic. First, sneak a peek at this site need to lubricate the key socket. You can use graphite powder, or a silicon aerosol spray. Make sure that the ignition cylinder is clean and has no loose springs or obstructions. Battery If your car isn't starting it could be because the battery is dead. This is a frequent issue that can be fixed by a jump or charging the battery. If this does not solve the problem, it is possible that your ignition switch is bad. This component supplies battery power to other electrical components, including the starter motor and ignition coil. If the ignition switch is defective it will not allow current to flow through and the engine won't begin. The battery is the source of all the electrical energy you use in your vehicle. It's a black box with positive (+) and negative (–) terminals that are on top. The terminals could become corroded and prevent the battery from supplying power to the rest of the vehicle. You can clean the battery's terminals by disconnection of the battery and using a wire brush to remove any corrosion. You can also apply baking soda to clean the terminals. It's also possible that your car battery is at the end of its lifespan and requires replacement. A new battery will supply the right voltage to your vehicle's spark plugs which is necessary to ensure a functioning engine. The ignition coil is responsible for converting low voltage from the battery to high voltage, which will then ignite the spark plugs in your car to start the engine. If your ignition coil is defective and not functioning properly, it will not be able to ignite the plugs. The engine will not start. You can test the ignition coil by checking for a spark inside the engine or turning the key and seeing whether the engine is turning. You might also have to replace the starter motor. If you hear a grinding noise when you turn on your ignition, it means that the bearings in the starter are beginning to wear out. It is a costly repair, so it's best to replace your starter motor immediately if you notice signs of wear. The starter motor can be changed by replacing a few bolts and parts. Alternator The alternator is the one that charges your battery and also powers the electrical components of your vehicle while the engine is running. If you suspect a issue with your alternator, you should test the battery first. This will help you determine if the alternator is causing your battery to drain or the battery is just old and should be replaced. Your car's alternator also supplies power for your dashboard lights, windshield wipers and electric steering, power windows heated seats, and your radio when the car is running. A voltmeter can be utilized to check the voltage of your alternator and battery. If your battery is below 6 volts, then it needs to be charged or replaced immediately. A dead or weak battery will also prevent the starter motor from cranking the engine over and will require more jumper cables to start your car. Before you begin removing the alternator, make sure the ignition is turned off and that all doors are locked. Unplug the negative cable and store it in a safe place. Wear safety gear. Consult a repair manual specific to your vehicle for directions on how to remove the alternator or any other parts. If your vehicle has a warning light wire, you can disconnect it from the side of the generator after removing the belt. The wire will connect directly to the alternator terminal that is marked WL or IN. Some vehicles, however have a separate relay to perform this purpose. If your warning light doesn't blink, it's likely that you have a different issue. The alternator is a crucial part of your vehicle, and you should examine it regularly for signs of trouble. While you could perform some of the checks by yourself, you should bring your vehicle to Les Schwab for a free inspection and expert advice. Our trained technicians can examine your battery posts, battery (the terminals marked + and –) for corrosion, fuses, relays and voltage output, cold cranking amps and more to determine what the issue is. Starter Motor The starter motor is a crucial component of the ignition system. It is responsible for turning the engine so that it can take into air, which is essential to ignite the fuel. If your car won't start, it's typically caused by a problem with the starter motor. There are many methods of troubleshooting that can be used to assist you in identifying and fixing the issue. When you turn on your vehicle's ignition key, a switch inside the starter turns on a pinion-gear that fits into grooves in the flywheel. The pinion gear turns the flywheel, which starts the engine. The gear retracts when you release the key to prevent damage. The starter motor could be affected by a range of things, such as mechanical problems (such as teeth not meshing on the flywheel) or a dead cell. A defective starter motor will just sound like a dead battery. it'll make a clicking noise as it tries to turn over the engine, but won't. If the starter motor isn't working, one of the first things a mechanic will look at is the state of charge of the battery and its terminals. If the battery is depleted or has rust on its terminals it will need to be charged or replaced. Depending on the extent of the problem The mechanic can also test the solenoid on the starter using a multimeter. The solenoid is a huge magnet switch, transmits an energy surge from the long battery cables to the starter. This switch connects the bulky cable from the battery to the starter's windings that turn the motor. It also pushes a rod to actuate an engaging fork which pushes the pinion to automatically engage with the flywheel. A jumper wire can be used to disable the ignition. This is only an option for a short-term fix and you shouldn't attempt it unless you are certain of the procedure. You'll need to take care to connect your jumper wires to the battery terminals, and make sure that the switch is in the “Start position”. Ignition Switch The ignition switch is where you insert your car keys. It is used to start the engine and to send electrical current to the starter. However, it is not immune to wear like other parts of the car. The switch could also become stuck in its slot or be locked. You should check for problems frequently to be able to act before the car won't start. It could have been locked if the key is difficult to turn or gets stuck in the ignition. This issue is common in vehicles due to a lack lubrication. You can make use of a graphite or silicone-based oil to lubricate your release pin. Spray a bit of it into the ignition and then try moving the key. If it's stuck, make use of a piler or a hacksaw blade to assist in moving it. A problem with the ignition can lead to a number of other issues too. The anti-theft system might not function or the starter motor might not crank when you put in the key. This can also cause the secondary functions to stop working or stop functioning. A malfunctioning ignition switch could also leave you with a lot of extra wear and tear on other parts. If you have a keychain with multiple items, or a large one, it can stress the ignition switch, which can cause wear on the internal components. Extreme temperature fluctuations can affect the materials and lubricants used in the ignition switch. If you've purchased a replacement ignition switch, it's important to test it before reassembling the steering column and other parts. Be sure that the replacement ignition switch is working and that your engine is running smoothly. Also, make sure the new ignition switch is compatible with the vehicle's make and model. It may be worthwhile to hire a dealership to install the ignition switch for you if aren't confident in your ability to do so. They can also test and connect any other parts or even replace them.
