I am trying to drive an electrical vacuum pump from a car directly from 12 VDC.
Earlier, I succeeded with a different pump just by connecting them to DC power, the other pump (different brand) used around 10 A at 13.8 V.
But now I got a new pump (different manufacturer) which does not rotate when I plug the power. It just moves small steps each time I connect it.
It might be an AC pump, which seems strange to me for using it in a car. Can someone help me understand how to drive it?
I attach the image of the circuit inside after opening the cap in the electric side, next to the two leads.
The model of the pump is 59220-J5000. It looks exactly like this.. The resistance between the leads is about 0.2 ohm.
