..."I know that solenoids do not care about polarity,"..
True, unless the solenoid has a diode across it to suppress back emf. If fitted, the diode stops a high and potentially damaging voltage appearing across the solenoid when the current through it is cut off. Get the polarity wrong and the diode is, to all intents and purposes, a short circuit. Martin |
