How to Fix Car Ignition Switch Problems
There are many reasons why your car may start and run, but the ignition doesn't start the spark plugs. Some are simple and cheap to fix, while others require specialized equipment and the assistance of mechanics.
First, you need to lubricate the key socket. You can apply graphite powder or silicon spray. Make sure that the ignition cylinder is clean and has no obstructions or loose springs.
Battery
It could be that your battery is dead when your car won't start. This is a common problem that can be fixed by a jump or charging of the battery. If this doesn't solve the problem your ignition switch could be defective. This component is responsible for transferring battery power to other electrical components like the starter motor and ignition coil. If the ignition switch is damaged it is not able to allow current flow through, and the engine won't start.
The battery is the source of all electrical energy in your vehicle. The battery is a black, slender box with positive (+) and negative (-) terminals on the top. The terminals may become corrosion-prone, which can stop the battery from providing power to the rest the vehicle. Clean the battery's terminals by disconnection of the battery and using a wire brush to remove any corrosion. You can also clean the terminals with a baking soda solution.
Your car battery may also be nearing the end of its life and need to be replaced. A new battery will supply the correct voltage to your vehicle's spark plugs which is essential for a properly working engine.
The ignition coil is responsible for converting low voltage from the battery into high voltage, which will then ignite the spark plugs in your car to start the engine. If the ignition coil is damaged it will not be capable of sparking the plugs, and the engine won't start. You can test the ignition coil by checking for a spark inside the engine or turning the key to see whether the engine is turning.
You may also need to replace the starter motor. If you hear a grating sound when you turn on your ignition, this means that the starter bearings are worn out. G28CarKeys could be a costly repair so it is best to replace your starter motor immediately if you begin to notice signs of wear. It's an easy process that requires replacing the bolts and a few components.
Alternator
The alternator is the one that charges your battery and powers the electrical parts of your vehicle while the engine is running. Examine the battery first if you suspect your alternator may be malfunctioning. This will help you determine whether your alternator is causing the battery to run out or whether the battery is just old and requires to be replaced.
While the vehicle is in idle, the alternator provides power to the dash lights and radio. It also powers the windshield wipers as well as the power windows, electric steering, the heated seats and the power windows. A voltmeter can be used to check the voltage of your alternator and battery. If your battery's voltage is lower than 6 volts it should be charged immediately or replaced. A dead or low-volt battery will also prevent the starter motor from turning the engine and will require additional jumper cables to get your car started.
Before you begin to dismantle the alternator, switch off the ignition and lock all doors. Remove the negative cable and store it in a safe place. Wear safety equipment. Refer to a repair manual specific to your vehicle for instructions on how to remove the alternator or any other components.
If your vehicle has a warning light wire, you can remove it from the back of the generator following taking off the belt. This will usually connect directly to the alternator's terminal that's marked either WL or IND. Some vehicles have a separate relay that can perform this function. If your warning light doesn't blink, it's likely that there is an issue with your vehicle.
The alternator is a vital component in your vehicle, and you should examine it regularly to look for signs of problems. You can perform some of these checks yourself, but it is recommended to bring your vehicle into Les Schwab so that they can inspect it and give you expert advice. Our technicians can test for corrosion on your battery posts, battery (+ and +) fuse, relays, and fuses and voltage output as well as cold starting amps and much more.
Starter Motor
The starter motor is an essential component in the ignition system. It turns the engine over to allow air to be sucked in and ignite the fuel. When your car won't start it's usually due to a problem with the starter motor. Fortunately, there are several ways to troubleshoot that can aid in diagnosing and fixing the problem.
When you turn on your vehicle's ignition the switch inside the starter is activated by a pinion gear that fits into grooves on the flywheel. The pinion gear turns the flywheel which starts the engine. The pinion gear retracts when you release the key to avoid damage.
The starter motor can be affected by a number of things, such as a mechanical problem (such as teeth not meshing on the flywheel) or a dead cell. Often, a defective starter motor can sound like a dead battery; it will make a clicking sound as it tries to turn the engine, but won't.
The condition of the battery and the battery's terminals will be checked by a technician if the starter motor doesn't work. If the battery is depleted or has rust on its terminals, it'll require charging or replaced.
Depending on the severity of the issue The mechanic can also test the solenoid on the starter using a multimeter. The solenoid is a large magnetic switch that sends an electric current from the thick battery cables to the starter. This switch connects the bulky cable from the battery to starter's windings which will turn the motor. It also pushes the rod to activate an engaging fork that pushes the pinion to automatically engage with the flywheel.
Another option is to disable the ignition switch by using a jumper wire. This is only a temporary solution, and it isn't recommended unless you're able to do it correctly. You'll need to be careful 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 the place where you insert your car key. This allows the system to enable electrical flow to your starter and to start the engine, however it's not immune from wear and tear like other car parts. The switch can also become stuck in its slot or locked. It is important to check for issues frequently to be able to act before the car won't start.
It could be locked if the key is difficult to turn or becomes stuck in the ignition. This issue occurs in many vehicles due to a lack grease. You can apply a graphite- or silicone-based oil to lubricate your release pin. Spray a small amount into the ignition, and then try moving the key. If it's still stuck, make use of a piler or a hacksaw blade to help move it.
An ignition issue can lead to a number of other issues too. The anti-theft function may stop working or the starter motor could not start when you insert the key. It could also cause other functions to cease functioning or cease to function at all.
A damaged ignition switch could also cause a lot of extra wear and tear on other components. For instance, if carry a bulky keychain or multiple items on your keychain it could put strain on the ignition switch when you plug it in, and could increase the wear on its internal components. Extreme temperature fluctuations can affect the lubricants and materials in the ignition switch.
It is important to test the new ignition switch before reassembling other parts and the steering column. Make sure the replacement is working and that the engine is running without issue. Double-check the compatibility of the new ignition switch with your vehicle model 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 the replacement and install any other components that require connecting or replaced.
