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

Disconnect the electrical connector so that it doesn't interfere with the test. Set the voltmeter in the continuity or resistance modes and place one lead onto one of the terminals of the ignition switch.
