The final solenoid test.
Testing 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.
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.
You should see the voltage polarity toggle with each switch activation.
Just a short video to show how you can test a door lock actuator using a car battery or a car jumper.
Injury or death can result from electrocution if proper safety precautions are not observed.
Ensure that all electrical power is shut off and disconnected before proceeding.
Here we have soldered all the components on the perf board so that it can be mounted on the door easily.
Unplug the door lock actuator electrical connector.
Test the door lock solenoid.
Circuit breaker box should be locked by personnel following this procedure.
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.
Once you are ready with the code and hardware you can start testing the solenoid door lock project.
