Because it isn't able to harness the full power of devices such as the starter, it's a lighter component that's less likely fail. However it's still possible for the switch to become damaged or damaged or corroded.

A bad switch can be identified by a difficulty turning the key. This can be caused by many things, including incorrectly inserting the key or deteriorating the mechanism over time. It's not unusual to see people mix keys with someone else's. This can result in mechanical damage.

If the switch isn't functioning there are a few things you could try before calling a locksmith. First, ensure that the battery is fully charged and there aren't any other electrical issues within the system. Also, you should examine the voltage of every component to determine if it's capable of supplying enough power. After you've completed these steps, it's time to start troubleshooting.

Fortunately the ignition switch is simple to replace. It is connected to the ignition module, a round piece of equipment that holds everything together.

You can use a voltmeter quickly test the van ignition repair switch and ignition coil. The voltmeter should read around 12.6 volts when the ignition switch is in the run position. If the voltage drops below that, it means there's an open circuit within the system. This could be at the solenoid, the battery or the ignition coil itself.

Remove the electrical connector so that it does not interfere with the test. Then set the voltmeter to the resistance or continuity mode and place one lead on one of the terminals on the ignition switch. The other leads should go to the positive terminal on the battery. If the voltmeter reads "open" or doesn't register any voltage then it's time to replace the switch.

When changing the switch, make certain to use a new ignition cylinder and a top quality key cut to ensure that your car will start and run properly.
