How to Fix Car Ignition Switch Problems There are a variety of reasons your car might start and run, but the ignition doesn't start the spark plugs. Some are easy and inexpensive to repair, while others require special equipment and the help of an expert mechanic. The first step is to lubricate the key socket. You can apply graphite powder or silicon spray. Also, make sure the ignition cylinder is free of any obstructions and loose springs. Battery It could be that your battery is dying if your car won't start. This is a frequent issue that can be solved with a jump or charging the battery. If this does not fix the problem your ignition switch could be defective. This component is responsible for transferring power from the battery to other electrical components like the starter motor and the ignition coil. If the ignition switch is damaged it will not allow current to flow through, and the engine won't start. The battery is the source of all electrical energy in your vehicle. It's a black, insulated box with positive (+) and negative (–) terminals on the top. The terminals could be corroded and stop the battery from supplying power to the rest the vehicle. By disconnecting the battery, you can make use of a wire bristle to get rid of any corrosion. You can also clean the terminals using baking soda as a solution. It is possible that your vehicle's battery has just reached the end of its lifespan and needs to be replaced. A new battery will supply the proper voltage to your vehicle's spark plugs, which is required to ensure that your engine is running properly. The ignition coil converts low voltage from your battery into high voltage, which causes it to ignite the spark plugs in your car and start the engine. If the ignition coil is damaged, it won't be capable of sparking the plugs and your engine won't start. You can test the ignition coil by checking for a spark in the engine or turning the key and seeing whether the engine spins. You might also have to replace the starter motor. If you hear a grating sound when you turn the key in your ignition, it means that the bearings inside the starter are beginning to wear out. It could be a costly repair, so it's best to replace your starter motor as soon as you begin to notice signs of wear. The starter motor can be changed by replacing a few bolts and components. Alternator The alternator is the one that charges your battery and powers the electrical components of your car when the engine is running. If you suspect that there is a problem with your alternator, you must first test the battery. This will allow you to determine if your alternator draining the battery, or if your battery is old and requires replacement. Your car's alternator also supplies the power to the dashboard lights, windshield wipers, power windows, electric steering, heated seats and your radio while the car is running. You can use a voltage meter to check your battery and the alternator for the proper voltage levels. If your battery's voltage is lower than 6 volts, it must be charged immediately or replaced. A low or dead battery will also prevent the starter motor from cranking the engine, and will require more jumper cables to get your car started. Before you start dismantling the alternator, make sure the ignition is turned off and all the doors are locked. Also, disconnect the negative cable from the battery, then tuck it away in a safe place and put on your safety equipment. Refer to a vehicle specific repair manual to learn how to access the alternator as well as any other parts you need to remove. After you've removed the belt, if your vehicle is equipped with one, disconnect the warning light wire from the back of the alternator. This wire will usually connect directly to the alternator's terminal that's marked WL or IND. Certain vehicles have an additional relay that performs this function. If your warning light does not blink, it's likely that there is an issue with your vehicle. It is recommended to regularly check your alternator for any indications of a malfunction. While you could perform some of the checks by yourself, you should bring your vehicle into Les Schwab for a complimentary inspection and expert advice. Our technicians will test for corrosion on your battery, battery posts (+ and +) and relays, fuses, and voltage output and cold starting amps and many more. Starter Motor The starter motor is an essential component of the ignition system. It is responsible for turning over the engine to suck into air, which is required to ignite the fuel. It is typical that the starter motor will be the cause when your car won't turn over. There are a number of troubleshooting techniques that can help you diagnose the issue and fix it. When you turn on your vehicle's ignition key, a switch inside the starter engages a pinion-gear that fits into grooves of the flywheel. The pinion gear is then turned the flywheel, which begins the engine. When you release the key, the pinion gear retracts and is released from the flywheel to prevent damage. There are a variety of things that could go wrong with the starter motor for example, an electrical issue in the internal windings, a mechanical issue (such as teeth no longer connecting to the pinion gear or flywheel) or a dead battery. A malfunctioning starter motor may sound like a dead phone battery. It will make a clunk sound as it tries to turn the engine. The condition of the battery and the terminals of the battery will be examined by a mechanic if the starter motor doesn't work. If the battery is corroded or is depleted it must be charged or replaced. Depending on how severe the issue is, a mechanic may also test the solenoid using a multimeter. The solenoid is a huge magnet switch, transmits a surge of power from the battery cables to the starter. This switch connects the thick cable from the battery to starter's windings that turns the motor. It also pushes a rod to actuate an engaging fork, which causes the pinion to automatically engage with flywheel. A jumper wire can be used to disable the ignition. This is only a temporary fix, and you should not try it unless you're sure how to do it. You will need to carefully connect your jumper wires the battery terminals, and make sure that the switch is in the “Start position”. Ignition Switch The ignition switch is where you insert your key into the car. This will enable electrical flow to your starter and start up the engine, however it's not immune to wear and tear as other car parts. The switch may also get stuck in its slot or be locked. It is important to check for issues regularly to identify the problem before your car doesn't start. If your key is a struggle to turn, or is stuck in the ignition, it may be locked. This problem is common in vehicles because of a lack oil lubrication. You can use a silicone or graphite-based oil to lubricate your release pin. Spray some lubricant onto the ignition, and then move the key. If it's stuck, employ a piler or hacksaw blade to help move it. A problem with the ignition could lead to other problems. The anti-theft system may stop working, or the starter motor may not start when you plug the key in. car ignition replacement near me can also cause auxiliary functions to cease functioning or cease to function altogether. A damaged ignition may cause extra wear and tear to other components. If you have keys that have multiple items, or a bulky one, this can cause strain on the ignition switch, which can cause wear on the internal components. Extreme temperature fluctuations can impact the materials and lubricants used in the ignition switch. Once you have a replacement ignition switch, it's crucial to test it prior reassembling the steering column and the other components. Make sure that the switch is working and that the engine starts without any issues. Verify the compatibility of the new ignition switch with the vehicle's model and make. It could be worth it to have a dealership install the ignition switch for you if aren't confident in your ability to install it. They can also test and connect other parts or replace them.
