    Hey rails. Im full of questions these days due to not having to move form my Bldg. that was sold, luckily to a new landlord who was not looking to raze the building and re-build a mega-mansion. Therefore I'm can now continue on my layout... Whoof !! I'm safe !!
    I have 2 or 3 pesky Walthers/Shino code 70 & 83 switches of which I know are power routing types..Obviously loco stall-outs on their points is due to those flimsy little fish-plates that the points swivel on ..I believe the cure is a matter of soldering a wire form the frog end of the points ,across the rail gap and onto the fixed rail before the frog...Please , if this is correct so far, tell me how to do this wiring job without melting the plastic ties..I have the soldering iron type (constant heat), not the triggered gun type of iron...BTW, these stall-outs are not short cicuit kind ( metal wheels crossing + - ), because NCE Power Cab is not shutting down during stall-outs..It's a continuity problem . ........Mark

    MarkInLA,

    That's the way I fix Atlas turnouts (Mark IIIs even) when they get quirky. I use some leftover decoder wire and put rosin core paste flux where the jumper wire will be soldered on both the point and the fixed rail. The wire is stripped and tinned on both ends. I've also read where one person cut a short piece of lamp cord, stripped the insulation, unraveled the bare cord, and used one of the wires for the jumper wire.

    I use a soldering iron tip that tapers to a fine point and using tweezers or small needle nose pliers, hold one end of the wire to the spot with the flux. I take the point of the iron, put a small dab of solder on it and take it immediately to the join spot. I touch it until the flux smokes off and the solder flows to the joint. Maybe a couple of seconds. The key to all this is practice, practice, practice. I used a small piece of scrap flex track and just kept soldering jumper wires between two different spots until I got the hang of it. My practice pieces have jumper wires soldered all over the inside and outside of the rails. You want to do it quickly, but not so quick you leave a cold solder joint.

    Good luck!
