You can use a voltmeter quickly test the ignition switch and ignition coil. The voltmeter should read approximately 12.6 volts when the ignition lock repair services switch is in the running position. If the voltage falls below that level, it's a sign there's an open circuit in the system. This could be at the battery, the solenoid or even the ignition coil itself.

Remove the electrical connector from the ignition switch to ensure that no other components can interfere with your test. Set the voltmeter on the resistance or continuity modes and connect one lead onto one of the terminals on the fix ignition switch switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter shows "open" or doesn't show any voltage it's time to replace the switch.
