How to Fix Car Ignition Switch Problems
There are a variety of reasons your car may run and start, but the ignition doesn't turn on the spark plugs. Some are easy and cheap to fix, others require specialized tools and help from an expert mechanic.
Lubricate the key socket first. You can apply graphite powder, or a silicon aerosol spray. Make sure that the ignition cylinder has no loose springs or obstructions.
Battery
If your car isn't starting it could be due to the battery being dead. This is a common problem that can be solved with either charging your battery or the jump. If this doesn't solve the problem, it is likely that your ignition switch is not working properly. The switch is the one that supplies battery power to the other electrical components, like the starter motor and ignition coil. If the ignition switch is defective it will not allow current to flow through, and the engine will not start.
The battery is responsible for all the electrical energy that is used in your vehicle. It's a black, insulated box with positive (+) and negative (-) terminals that are on the top. The terminals may become damaged, preventing the battery from supplying power to the rest of the vehicle. You can clean the battery's terminals by disconnecting the battery and using a wire brush to get rid of any corrosion. You can also clean the terminals with a baking soda solution.
Your car's battery could be nearing the end of its lifespan and need to be replaced. A new battery will provide the right voltage to your vehicle's spark plugs which is essential to ensure a functioning engine.
The ignition coil converts the battery's low voltage into high voltage, which causes it to ignite the spark plugs inside your car, and to start the engine. If the ignition coil is damaged it won't be able spark the plugs. Your engine won't start. You can test the ignition coil by checking for a spark inside the engine or turning the key and observing whether the engine is turning.
You might also have to replace your starter motor. If you hear a grating sound when you turn on your ignition, this means that the starter bearings are worn out. It can be an expensive repair, so it's best to replace your starter motor immediately if you detect signs of wear. The replacement of the starter motor is an easy task that requires replacing a few parts and bolts.
Alternator
The alternator charges your battery and also powers the electrical components of your car when the engine is running. If you suspect that there is a problem with your alternator, you should first test the battery. This will allow you to determine if your alternator is draining the battery or if your battery is old and needs replacement.
While the vehicle is in idle the alternator is able to supply power to the dash lights as well as the radio. It also powers the windshield wipers as well as the power windows, electric steering, heated seats and the power windows. A voltmeter can be used to test the voltage of your alternator and battery. If your battery is less than 6 volts, it should be replaced or charged right away. A low or dead batteries will also stop the starter from turning the engine over and may require additional jumper cables to begin your car.
Before you begin dismantling the alternator, ensure the ignition is off and all doors are locked. Disconnect the negative cable and store it in a safe place. Wear safety gear. Refer to a repair manual specific to your vehicle for directions on how to remove the alternator or any other components.
After you've removed the belt, if your vehicle has one remove the warning light wire from the back of the alternator. It will typically connect directly to an alternator's terminal that's labeled either WL or IND. Some vehicles, however, have a separate relay for this purpose. If the warning light doesn't blink, you may suspect a different problem.
The alternator is a vital component in your vehicle, and you should inspect it regularly for signs of trouble. You can do certain of these tests yourself, but it's best to bring your car into Les Schwab so that they can inspect it and give you expert advice. Our technicians can test for corrosion on your battery, battery posts (+ and -) fuse, relays, and fuses as well as voltage output and cold starting amps and many more.
Starter Motor
The starter motor is a crucial element of the ignition system. It turns the engine over to allow air to be sucked into it which will ignite the fuel. If your car isn't starting, it is often due to a problem with the starter motor. There are a number of troubleshooting techniques that can help you diagnose the issue and fix it.
When you turn on your car's ignition key, a switch within the starter activates a pinion gear that fits into grooves of the flywheel. The pinion gear turns the flywheel which initiates the engine. The gear retracts once you release the key to prevent damage.
There are many things that could cause problems with the starter motor, such as an electrical problem in the internal windings, a mechanical issue (such as teeth no longer meshing with the pinion gear or flywheel) or a dead battery. A damaged starter motor could sound like a dead phone battery. It can make a clicking sound as it tries but cannot turn the engine.
The state of charge and the terminals of the battery will be checked by a mechanic if the starter motor doesn't work. If the battery is depleted or has corrosion on its terminals, it will require charging or replaced.
Depending on the degree of the problem The mechanic can also examine the solenoid of the starter with a multimeter. The solenoid is a large magnetic switch that transmits the power of the battery cables that are long and thick to the starter. This switch connects the bulky cable from the battery to the windings in the starter which turn the motor. It also triggers an axis rod to trigger an engaging fork that pushes the pinion to automatically engage with flywheel.
A jumper wire can be used to bypass the ignition. This is a temporary option, and it isn't recommended unless you know how to do it right. You'll need to take care to route your jumper wires to the battery terminals, and then make sure that the switch is in the "Start position".
Ignition Switch
The ignition switch is where you insert your keys into the car. This will allow electrical flow to the starter and then start the engine, but it isn't immune to wear and tear as other parts of your car. The switch can also become stuck in its slot or locked. It's important to check it frequently for issues so you can take action before the car doesn't start.
It is possible that your key was locked if your key is difficult to turn or gets stuck in the ignition. This issue occurs in many vehicles because of a lack lubrication. You can apply 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, use a piler or hacksaw blade to help move it.
A problem with the ignition can cause a variety of other issues, too. The anti-theft device may not function, or the starter motor might not start when you plug the key in. It could also cause other functions to lose power or not work at all.
A damaged ignition switch could also cause a lot of extra wear and tear on other components. For instance, if you carry a bulky keychain, or several items on your keychain it could put strain on the ignition switch when you put it in and accelerate the wear on its internal components. Extreme temperature changes can also affect the materials and lubricants used in the ignition switch.
car ignition replacement is important to test the replacement ignition switch before reassembling other parts and the steering column. Check that the replacement works and that the engine is running without issue. It is also important to confirm that the new ignition switch is compatible with your vehicle's model and model. If you're not confident in your ability to install a new ignition switch, it might be worth employing a dealership service shop to do it for you. They can also test and connect any other parts or even replace them.
