Question 12V wiper motors not running

Hello guys, i bought two new 12V wiper motors. I wanted to know if the motors are running, so i tried connecting pins straight to the power supply, they both moved little bit, but then they stopped and i cant get them to move again. Does anyone know what should i try?

Hello friend, what is your power supply? Battery or Power supply?

If it is a computer power supply or a power supply from an LED strip, the power supply may have gone into protection (you need to unplug it from the outlet and reconnect it after one minute).

I also want to add that you need to disconnect the mass wire from the motor housing, otherwise you will have a short circuit since you have a hinged frame and two electric motors working in different directions.

I have a LED strip power supply, but this is not the case, i tried reconnecting it several times.

What do you mean by the mass wire? When i was testing them, they were mounted like this, on aluminium "bar".

You use automotive gearboxes as a rule, the negative wire of this gear is fixed to the housing of this gearbox. In cars, the body is a disadvantage. Therefore, it is necessary to disconnect the ground wire from each motor reducer, otherwise there will be a short circuit.

Try to connect to one motor reducer first by applying 12 volts to it. The disadvantage will be the case of the motor reducer. It would be nice to see your video for a better understanding of how you connect.

If I explained it incomprehensibly, you can remove the hood from the motor reducer and see that one brush is attached to the body, it needs to be disconnected from the body since you have an aluminum simulator. If the gaming platform were made of wood or plastic, this could not be done since neither wood nor plastic conducts electricity.

I know what are you talking about, it is the ground isolation what DMax in his video did. But my motors are not connected to the body.

It's just under this board with brushes that you can see whether the brush is attached to the case or not, but unfortunately you didn't show the photos.

You can also use a 12 volt car battery to test the gear motor. It is enough to connect to the gear motor as shown in the photo. If you reverse the polarity, the motor will rotate in the opposite direction. If you are interested in how it works, you can go to YouTube and get acquainted.
