Graskie Posted January 18, 2015 Share Posted January 18, 2015 Swap your wires around from power source (track, say) to point motors, or from accessory decoder to the point motor if powered direct from that? Link to comment Share on other sites More sharing options...
Gazah Posted January 18, 2015 Author Share Posted January 18, 2015 Swap your wires around from power source (track, say) to point motors, or from accessory decoder to the point motor if powered direct from that?Hi Graskie,So if I am using the Hornby decoder, and in port 3 Red is + Wire and green is - wire you suggest just swapping these over, will it not damage the deocder?

Graskie Posted January 18, 2015 Share Posted January 18, 2015 I don't see why it should, on the face of it, but someone else needs to confirm or deny that. I haven't actually set up any accessory decoders yet, but my suggestion seems pretty reasonable. It should just reverse power to your point motors, and hopefully then fit in with RM showing the correct setup. Link to comment Share on other sites More sharing options...
Graskie Posted January 18, 2015 Share Posted January 18, 2015 Incidentally, Gazah, are you powering each point motor separately or from just one feed leading from one point motor to the other? If the latter, then you would, of course, need to switch over the two wires between the point motor terminals as well, so that they both have the same polarity.

Graskie Posted January 18, 2015 Share Posted January 18, 2015 Thinking about it, you don't need to switch the wires from your decoder. As an alternative it could perhaps work if you just switch your point terminals, still ensuring the same polarity for both as described before.

Fishmanoz Posted January 18, 2015 Share Posted January 18, 2015 Take a look at the lengthy discussion on this in the thread "Points indicator in passing loop" towards the bottom of RM forum page 1. And to clarify, swapping the positive and negative wires from decoder to point won't damage snything. In fact, even getting it wrong completely and putting common to positive or negative won't do any damage, it just won't work. Link to comment Share on other sites More sharing options...
