Hi,
I am running an oo gauge layout with 2 main running lines via DC or analog as some people call it. Ive have wired up my points with Guagemaster pm20 point motors, controlling them with the Gaugemaster CDU point controller, the one that does up to 18 points. The track is controlled with a Gaugemaster model Q i think, the 4 track one, I have 2 passing loops, one on each of two main running lines and on these loops I have wired the 2 points at each end to change accordingly at the same time. My issue is that the points on track one work perfectly but the points on track 2 do not. What happens is when I disconnect one point and switch the other so that they are correctly aligned, when reconnected they always end up switching to opposite ways to each other. I'm absolutely baffled by this as nothing I've done such as swap wires around hoping to change polarity, or disconnect one then flick the switch and then reconnect, doesn't do anything to rectify the situation. Both points are connected to the same common return which is what I've done with my other tracks points which work fine. I've been fiddling about with it for ages but to no avail. Is anyone able to shed any light and point me in the right direction?
Many thanks.
David.
