This could be the solenoid, battery, or the ignition coil.

Disconnect the electrical connector so that it does not interfere with the test. Then, set the voltmeter to the continuity or resistance mode and place one lead on one of the ignition switch terminals. The other lead should be connected to the positive terminal of the battery.
