However wonder if over time the plunger will become magnetized and just maybe start sticking to something metallic within the e unit. I think I recall reading that some accessories solenoids or other magnetic (the ubiquitous up/down crossing gates comes to mind) might exhibit stickiness after operating on DC, but could be wrong.
Also be aware that electrically, the accessory solenoids are wound for AC operation with the windings acting as impedance (i.e. AC resistance) choke coils with a relative low DC wire resistance. When DC is applied there is no impedance to limit current, just the wire resistance, and depending on the voltage and coil DC resistance, the winding MIGHT become overheated distorting the coil form jamming the plunger or wire just burns open.
Anyone run into this problem?
