How to Fix Car Ignition Switch Problems There are a myriad of reasons your car might run and start but the ignition won't start the spark plugs. Some are easy and cheap to fix, while others require special tools and assistance from an expert mechanic. The first step is to lubricate the key socket. You can use either graphite powder, or a silicon aerosol spray. Also, make sure the ignition cylinder is free of any obstructions and loose springs. Battery If your car doesn't start, it could be because the battery is dead. This is a common issue that can be fixed by getting a jump or charging the battery. If this doesn't solve the issue your ignition switch could be bad. This component is responsible for transferring battery power to other electrical components like the starter motor and the ignition coil. If the ignition switch is damaged it won't permit current to flow through and the engine won't start. The battery is the main source of electrical energy in your vehicle. It's a black, insulated box with positive (+) and negative (–) terminals on top. The terminals may be corroded and stop the battery from supplying power to the rest the vehicle. By disconnecting the battery, you can use a wire bristle to get rid of any corrosion. You can also clean the terminals using a baking soda solution. The battery in your car could be at the end of its life and requires replacement. A new battery will provide the proper voltage to the spark plugs in your vehicle which is necessary to ensure a functioning engine. The ignition coil is responsible for changing 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 faulty, it won't be in a position to ignite the plugs and your engine won't start. The ignition coil can be tested by checking the engine for a spark or turning the key to determine whether it spins. You may also need to replace the starter motor. If you hear a grating sound when you turn on your ignition it is a sign that the starter bearings are wearing out. This could be a costly repair, so it's best to replace the motor of your starter early in the event that you notice signs of wear and wear. The starter motor can be replaced by replacing the bolts and components. Alternator The alternator is the one that charges your battery and powers the electrical components of your vehicle while the engine is running. Check the battery first if you suspect your alternator is failing. This will allow you to determine if your alternator draining the battery, or if your battery is old and in need of replacement. While the vehicle is in idle the alternator is able to supply power to the dash light and radio. It also powers the windshield wipers, the power windows, electric steering, heated seats, and the power windows. You can use a voltage meter to examine your battery and alternator for proper voltage levels. If your battery has less than 6 volts, it should be charged immediately or replaced. A dead or low-volt battery will also prevent the starter motor from cranking the engine, and will require more jumper cables to start your car. Before you begin dismantling the Alternator, shut off the ignition and lock all doors. It is also important to disconnect the negative cable from the battery, tuck it away in a safe location and put on the safety equipment. Consult a vehicle's specific repair manual for instructions on how to access the alternator, as well as any other components you require to take off. If your vehicle is equipped with a warning light wire, you can remove it from the back of the generator following taking off the belt. This wire will usually connect directly to a terminal on the alternator that's marked either WL or IND. Some vehicles, however, have a separate relay to perform this function. If the warning light doesn't appear, you must be able to identify a different issue. The alternator is an essential part of your vehicle, and you should examine it regularly to look for signs of problems. You can carry out some of these checks yourself, but it's best to bring your vehicle to Les Schwab so they can inspect it and provide you with expert advice. Our technicians can test for corrosion on your battery, battery posts (+ and –) fuse, relays, and fuses and voltage output, cold starting amps, and many more. Starter Motor The starter motor is a crucial element of the ignition system. It is responsible for turning the engine to take into air, which is necessary to ignite the fuel. If your car isn't starting, it's typically caused by a problem with the starter motor. There are a variety of troubleshooting techniques that can assist you in identifying and fixing the problem. When you turn on your car's ignition key, a switch within the starter activates a pinion gear that is fitted into grooves on the flywheel. The pinion gear turns the flywheel which begins the engine. When you release the key, the pinion gear retracts, and disengages from the flywheel, thereby preventing damage. There are many things that could cause problems with the starter motor, including an electrical failure in the internal windings, mechanical issues (such as teeth not meshing on the pinion gear or flywheel) or a dead battery. A defective starter motor will just sound like a dead battery. it'll make a clicking noise as it tries to turn the engine, but won't. The condition of the battery and the terminals of the battery will be examined by a mechanic in the event that the starter motor does not work. If the battery is corroded or is low, it will need to recharged or replaced. Depending on how serious the issue is, the mechanic could also test the solenoid using a multimeter. The solenoid is a large magnetic switch that sends an electric current from the thick battery cables to the starter. The switch connects the battery cable to the windings inside the starter that make the electric motor turn as well as it pulls an actuator rod that turns on an engaging fork that in turn pushes the pinion gear to automatically engage with the flywheel. A jumper wire can be used to bypass the ignition. This is a temporary solution but it shouldn't be recommended unless you know how to do it correctly. ignition lock repair near me will need to carefully route 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 key. This allows the system to allow 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 could also get stuck in its slot or locked. It is important to regularly check it for problems so that you can act before the car stops working. If your key is experiencing a struggle to turn or it is stuck in the ignition, it might have been locked. This is a problem that is common in vehicles because of a lack grease. Using a silicone or graphite-based lubricant on the release pin can aid. Spray a small amount into the ignition and then try moving the key. If it's stuck then try using a piler or hacksaw blade. An issue with the ignition may lead to other problems. The anti-theft feature could stop working or the starter motor may not start when you insert the key. This could also cause the auxiliary functions to stop working or cease to function. A malfunctioning ignition could cause additional wear and tear to other parts. For instance, if carry a bulky keychain, or several items on your keychain, it could strain the ignition switch when you plug it in and accelerate the wear on its internal components. Extreme temperature fluctuations can impact the materials and lubricants used in the ignition switch. It's important to test the replacement ignition switch prior to assembling the other components and the steering column. Make sure the replacement is working and that the engine starts without any issues. Also, make sure the new ignition switch is compatible with your vehicle's make and model. It may be worthwhile to get a dealership to install the ignition switch for you if are not confident about your ability to install it. They can also test the replacement and install any other components that require connecting or replaced.
