Testing Door Lock Solenoid

Just a short video to show how you can test a door lock actuator using a car battery or a car jumper.

Testing door lock solenoid.

The final solenoid test. You should see the voltage polarity toggle with each switch activation. For the final solenoid test that would determine if your solenoid is damaged or not you would have to connect the red probe of your multimeter to the negative terminal of the solenoid and the black probe of the multimeter to the positive terminal. Then use your test light or digital meter to check for power and ground at the connector when you operate the lock unlock switch.

Test the door lock solenoid. If your solenoid is being used as part of a car it can still be tested with a multi meter but the continuity test can be done without it. Ensure that all electrical power is shut off and disconnected before proceeding. So to test it mount the perf board on the door frame and magnet on the door so that it can detect the door movement.

Door lock systems operate the actuator by toggling positive negative voltage to the actuator. Locate the solenoid generally found either next to or as a part built into the starter and then with a friend s help insert and turn the vehicle s key. Unplug the door lock actuator electrical connector. Here we have soldered all the components on the perf board so that it can be mounted on the door easily.
