Arnold D. Cribari posted:I have LC+ New Haven FAs with electrocouplers. At 16 volts, the electrocouplers made the sound of firing open, but did not open. However, at 18 volts they did both.
I've found that Lionel electrocouplers often take 18 volts to operate whereas other brands (Atlas, Weaver, K-Line and MTH Proto-1) typically operate reliably at 12-14 volts.
