RMweb Gold john new Posted May 20, 2011 RMweb Gold Share Posted May 20, 2011 This is an analogue DC answer so I don't know if it applies to DCC but probably does as surely you still need to keep the + confined to one rail and the - to the other. Fault I've had myself in past with a DC common return system and most likely a short caused by the V ending up trying to take both polarities at once as soon as the point blade makes contact. My guess is you have a cross connection somewhere, perhaps a distance away from the point, giving the cross feed. Again I know this is a standard DC answer but if all else fails add isolating gaps on all the exit roads. Link to comment Share on other sites More sharing options...

Suzie Posted May 20, 2011 Share Posted May 20, 2011 The wires from the frogs to the frog switches have probably been crossed over. Link to comment Share on other sites More sharing options...

Suzie Posted May 21, 2011 Share Posted May 21, 2011 Yes. If you have left the wires long enough you can probably just swap the switches over to the opposite motors and turn them round with having to do any soldering, otherwise you will have to resolder all the wires.
