I recently purchased a second hand reversing contactor. Although it doesn't look like it has ever been installed.
But when I have tried to trip either contactor I don't hear anything (no click).
I have done more research but I can't see anything that would make it more complicated than just applying 12v. I started by trying to trigger it through some 12v relays but when that failed I started to just manually touch the 12v wires on the terminals.
If it were only a problem with one side I would call it bad luck. But what are the chances of both sides being dead? That makes me think there is possibly more to this.
Any ideas? Is there some safety feature that is tripping me up?
It is a ZJQ-672.
I'm not overly concerned if it is dead but I didn't want to give up on premiturely.
If it is dead I will just use multiple single contactors controlled by my arduino.
