I bought a bunch of new 6-81952/53 switches at York and one of them has an issue. One LH 6-81953 switch will not accept programming. When I depress the programming switch button, the lamp never blinks (stays lit), so I cannot program it. Default SW #1 doesn't work, either.
I took the base off, and nothing out of the ordinary looked wrong. depressing the switch gave correct continuity. I decided to take the small PWB shown in the photo below (plagerized photo from GRJ) off a good switch and swap it with this. In doing so, the bad switch was now able to be programmed to a new switch number. I then put both switches back together. This temporarily solved my problem, as now I could address all switches, but would like to fix properly.
Does anyone know the P/N for this small PWB and where to get it from? I couldn't find anything on Lionel parts site, or on Brasseur's.
Thanks, Dave
