9 Lessons Your Parents Taught You About Fix Car Ignition > 자유게시판

How to fix car ignition (www.harimint.com link for more info) Problems

The car won't start unless the switch transmits an electrical signal to the starter. Over time wear and tear could cause the switch to fail.

You can remove the trim on your steering column using specialized tools to gain access to your ignition cylinder module. Refer to your repair manual for guidance on how to do this in a safe manner.

1. Make sure you check the Switch

One of the most frequently encountered ignition issues is a defective switch. It functions as bridge between two contacts, regulating the time when relays are activated and deactivated. It is less likely to fail due to the fact that it does not channel full power of devices such as the starter. The switch could still be damaged or damaged or corroded.

A bad switch can be identified by a difficult time turning the key. This could be due to a number of factors such as the wrong way to insert a key, or the mechanism being worn out over time. It's also common for people to mistake their keys to their car with the keys of someone else, which can result in mechanical damage.

Before contacting a locksmith, you may try a few options. First, make sure the battery is fully charged and that there are no other electrical issues in the system. It is also important to examine the voltage of each component to ensure that they are supplying enough power. After you've completed these steps, it's now time to start troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, a round piece of metal that holds everything together. It's necessary to use an elongated flathead as well as something that is long enough to push the pin into. You can use anything from a paintbrush to Kabob stick, but be careful of anything that is brittle, as it can break into the hole.

Remove any trimming pieces that overhang the switch once you're ready to work. After you've removed the trim pieces take off any screws that hold the switch in position. Then carefully take it off. Depending on the model, you may also need to disconnect any wires connected to it. If you have an instruction manual for your vehicle it will explain exactly how to do it.

If the ignition switch isn't working it's recommended to replace it by a professional. It's difficult to replace the ignition switch without removing the steering column. This could lead to the unintentional airbag deployment when you don't do it correctly. For this reason, it's best to have your local locksmith handle this for you.

2. Check the Wire

If you are unable to turn the key in the ignition or your car isn't starting, your issue could be related to any of the components in your car's ignition system. It is important to know how the ignition system works to be able to spot issues and make the necessary repairs.

The ignition switch is a low voltage multi-pole electrical switch that is turned by the key. It has four positions, including "off", "accessory", "run" and the "lock". When the switch is in the lock position (which usually has an indicator in red) the ignition circuit is in operation and it's impossible to start the engine.

You can use a voltmeter to quickly test the ignition switch or ignition coil. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage is lower than that then there is an open circuit somewhere within the system. This could be at the solenoid, the battery or the ignition coil itself.

Remove the electrical connector from the ignition switch so that there are no other components that could interfere with the test. Then you should set the voltmeter in the resistance or continuity mode and put one lead on one of the ignition switch terminals. The other leads should go to the positive terminal of the battery. If the voltmeter shows "open" or doesn't register any voltage then it's time to replace the switch.

When you're changing the switch, make certain to use a new ignition cylinder and a good quality key cut to ensure that your car will run and start correctly. When replacing the switch, make sure not to strike the pins of the ignition cylinder with your tools. In the event of a collision, they'll get stuck and your engine won't run. You'll need to take off the steering wheel as well as the gear selector in certain vehicles to get access to the ignition cylinder. This can be difficult, and it is not recommended until you have an owner’s manual that states it's safe. If you do not you could cause serious damage to your steering column and shift mechanism.

3. Check the Cylinder

If you've worked your way through the wiring, battery and ignition switch but you can't get your car ignition switch start, it could be time to check the cylinder. It's the component that holds your key and is mechanically connected to the steering wheel lock so a would-be thief can't control the car ignition key replacement without keys.

If your cylinder has started to wear out, you may find that the key doesn't turn. The pins in the cylinder may become stuck as they adapt to your key's shape. This can cause your car to not start. Or, the cylinder might be loose and a tap using the small hammer from a tack can aid in releasing it. Be careful not to jumble the springs within and make sure that your key is correctly placed before tapping.

If you have to jiggle and move the key around before it will begin, this is another indication that your cylinder is been damaged. This is a sign of trouble and must be addressed immediately because it will get worse with time.

To examine the cylinder you'll need to unplug your battery, and then remove the cover on your steering wheel until you can access the ignition module. The old ignition switch should be easy to take off, as will the cylinder made of steel. If you don't own a spare switch, you might be able to bring your original ignition cylinder as well as switch to locksmiths for reuse as long as they're in good condition. After replacing the switch and cylinder, be sure to reconnect the wiring harness and secure it and reattach any covers or panels you removed.

4. Check Spark Plugs

The spark plug is the last link in your ignition chain. The engine cannot start if the spark plug breaks. This could take the form of your car not running at all, or it may start but run poorly. In either case, it is likely that one or more things are hindering or preventing the flow of electricity across spark plug gaps, which in turn ignites the mixture of fuel and air in your engine.

Before you begin working on your spark plugs, make sure that you are working on a level surface and using protective gloves and tools to prevent getting struck. Spark plugs can be very hot and can cause serious injuries if touched with bare hands.

If a spark plug goes bad, you might notice that the tip of the electrode's central portion has a light gray or brown substance on it. The electrode could also be covered with a dark coating. The deposits or fouling may prevent high-voltage electrical current from crossing the gap of your spark plug and igniting an engine.

If you suspect your spark plugs could be the cause You can test them if you remove them from the tube that is inside the ignition coil. You can do this by disconnecting the coil from the plug wire, and following the proper procedure for your vehicle to remove any components that are covering the spark plugs. After you have removed the plugs, place them on a surface that is grounded, and start the engine. If they are working you will see an intense blue spark on the edge of the central electrode.

If you don't see a spark, you've found the issue. The next step is to work back through the ignition and key replacement system chain, testing each component until you can determine what is hindering the spark plugs from doing their job. All systems get older and eventually break, and this is particularly relevant to ignition systems. Routine maintenance can help to reduce the time it takes to repair and prevent an issue at the worst time.
