Afternoon gentlemen: (Gunrunner John, GGG, Jon)
I have a MTH RailKing NW-2 (PS1) Switcher (we call them "shunters" or a "shunting loco" here in Australia) that is going to pull duties in my newly created "freight/fiddle yard".
It has the "electro-couplers" at each end, but only the coupler that is nominated by the small switch under the cab (on the bottom of the chassis) will "fire" open from the transformer horn/whistle button. Because the loco will be entering and leaving the yard in different directions, this means the "armed" coupler may be at the wrong end of the loco to break-down or build-up consists.
Question: Can I install a "jumper" or "hot wire" between the positive (+) terminals of both coupler coils (front & rear) so both couplers fire open at the same time??
I realize one of the couplers will be open, and the other possibly closed most of the time, so "firing" both to the "open" position should not place too much of a strain on the electronics, yah think???
If I "jumper" a wire between the two positive (+) connections, and basically bypass the switch under the cab, will this do any harm to the PS1 circuit board?? This way I won't have to lift the loco off the tracks and change the switch position every time I want to use the other coupler.
I know first hand how scarce these PS1, 2, and 3 boards are, and I don't want any repeat of the problems I had with my RailKing PS3 "Challenger" late last year. Let's not go there if we don't have to!!!!
