Update: K-line MP15 Switcher K-2200series intermittent stopping | O Gauge Railroading On Line Forum

It now runs fine on "clear" track but stops on switches, remote sections, etc/

Hello, I've attempted unsuccessfully to repair a K-line switcher's intermittent, sudden stopping or reversing on my layout. It works perfectly on stationary test stand. The problem started after I replaced a broken off coupler. I thought I might have broken a pick up wire, but don't see one. Also, the "buttons" for uncoupling, touching the track; I covered them with tape for a test, but the problem continues. Any thoughts.

It sounds like a broken wire to me. I would take the shell off and run it, see if the light flickers when it stops or changes direction. If it does, you are definitely getting a power interruption to your reverse board. I would remove the e-clip and check the wires in the truck where they are soldered onto the copper strips and check the wires on the board.

I'd just check continuity between the rollers to start...

Closely examine the board. I found a bad solder joint on an engine with similar symptoms.
