15 Terms That Everyone Involved In Fix Car Ignition Industry Should Know
How to Fix Car Ignition Switch Problems
There are a myriad of reasons your car may start and run, but the ignition doesn't turn on the spark plugs. Some are easy and cheap to fix, others require specialized tools and assistance from a mechanic.
The first step is to lubricate the key socket. You can apply graphite powder or silicon aerosol spray. Also, ensure that the ignition cylinder is free of obstructions and loose springs.
Battery
If your car doesn't start, it could be because the battery is dead. This is a frequent issue that can be resolved by a battery charge or a jump. If this doesn't fix the issue, your ignition switch may be bad. This component supplies battery power to the other electrical components, like the starter motor and the ignition coil. If the ignition switch is faulty it will not allow current to flow through it and the engine won't begin.
The battery is responsible for all the electrical energy in your vehicle. It's a black box with positive (+) and negative (-) terminals on top. The terminals may become corroded, preventing the battery from supplying electricity to the rest of the vehicle. By disconnecting the battery you can make use of a wire bristle to get rid of any corrosion. You can also apply baking soda to clean the terminals.
Your car battery may also be nearing the end of its lifespan and need to be replaced. A new battery will supply the right voltage to your vehicle’s spark plugs. This is necessary to ensure that your engine is running properly.
The ignition coil is responsible for turning low voltage from the battery into high voltage that will spark your car's spark plugs to start the engine. If the ignition coil is damaged and not functioning properly, it will not be able spark the plugs. Your engine won't start. The ignition coil can be tested by examining the engine for sparks or turning the key to see whether it is turning.
It is also possible to replace the starter motor. If you hear a grinding sound as you turn on your ignition it means that the starter bearings are wearing out. car ignition barrel replacement near me could be a costly repair, so it's recommended to replace the motor of your starter early when you see any signs of wear and tear. The replacement of the starter motor is an easy task that requires the replacement of the bolts and a few components.
Alternator
The alternator is the one that charges your battery and powers the electrical components of your car while the engine is running. Test the battery first if you suspect that your alternator may be malfunctioning. This will help you determine if the alternator is draining the battery or if the battery is old and in need of replacement.
Your car's alternator also provides power for the dash lights, windshield wipers and electric steering, power windows as well as heated seats and your radio while the vehicle is idling. 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 replaced or charged right away. A dead or weak battery will also prevent the starter motor from turning the engine over and will require more jumper cables to start your car.
Before you begin dismantling the Alternator, turn off the ignition and lock all doors. Unplug the negative cable and secure it. Wear safety equipment. Consult a vehicle's specific repair manual for instructions on how to gain access to the alternator, as well as any other parts you need to take off.
After you've removed the belt, if your vehicle is equipped with one, disconnect the warning light wire from the back of the alternator. The wire will connect directly to an alternator connector marked WL or IN. Some vehicles, however have a separate relay to perform this function. If your warning light does not blink, you may suspect a different problem.
It is recommended to regularly check your alternator for any indications of a malfunction. You can perform some of these checks yourself, but it is best to bring your vehicle into Les Schwab so that they can inspect it and provide you with expert advice. Our technicians will test for corrosion on your battery, battery posts (+ and +), fuses, relays as well as voltage output and cold starting amps and much more.
Starter Motor
The starter motor is an essential element of the ignition system. It turns the engine to allow air to be sucked in and ignite the fuel. It is common that the starter motor will be the cause of your car won't turn over. Fortunately, there are several methods of troubleshooting that can be used to aid in diagnosing and fixing the problem.
When you turn on your vehicle's ignition, a switch in the starter turns on the pinion gear, which fits into grooves on the flywheel. The pinion gear is then turned the flywheel, which then starts the engine. When you release the key the pinion gear retracts, and disconnects from the flywheel to avoid damage.
There are many things that can cause problems with the starter motor, for example, an electrical issue in the internal windings, a mechanical problem (such as teeth not connecting to the flywheel or pinion gear) or a dead battery. A damaged starter motor could sound like a dead phone battery. It will make a clunk sound as it attempts to turn the engine around.
If the starter motor isn't working, one of the first things a mechanic should examine is the condition of charge on the battery and its terminals. If the battery is damaged or is low it needs to be recharged or replaced.
Depending on how serious the issue is, the mechanic can also test the solenoid using a multimeter. The solenoid is a massive magnetic switch that delivers the power of the thick battery cables to the starter. The switch connects the long battery cable to windings within the starter that actually turn the electric motor, plus it pushes an actuator rod that turns on an engaging fork that will then push the gear that pinions to automatically engage with the flywheel.
A jumper wire can be used to bypass the ignition. This is only a temporary solution, and it isn't recommended unless you know how to perform it correctly. You'll need to route the jumper wire through the battery terminals, and ensure that the switch is set to the "Start" position.
Ignition Switch
The ignition switch is the place where you insert your car keys. This will enable electrical flow to your starter and to start the engine, but it's not immune to wear and tear as other car parts. The switch may also become stuck in its place or become locked. You should check for problems regularly to identify the problem before your car doesn't start.
It could be locked if the key is difficult to turn or gets stuck in the ignition. This issue occurs in many vehicles because of a lack lubrication. Using a graphite or silicone-based grease on the pin that releases the key can aid. Spray a bit of it into the ignition and try moving the key. If it's still stuck make use of a piler or a hacksaw blade to help move it.
A problem with the ignition can lead to a number of other issues too. The anti-theft system might stop working or the starter motor may not turn on when you put in the key. This could also cause the auxiliary functions to stop working or cease to function.
A malfunctioning ignition switch could cause a lot of wear and tear on other components. For instance, if carry a bulky keychain or multiple items on your keychain, it could strain the ignition switch when you put it in, and could increase the wear and tear on its internal components. Extreme temperature fluctuations can impact the materials and lubricants in the ignition switch.
It is crucial to test the new ignition switch prior to assembling the other components and the steering column. Check that the replacement works and that the engine is running without issue. Also, make sure the new ignition switch is compatible with your vehicle's model and model. If you're not sure of your ability to install an ignition switch that is new it could be worth hiring a dealership service shop to complete the task for you. They can also test and connect other parts or replace them.
