Stephen, I fully understand your problem as I have the same point motors on some of my layout. I also use the Passing contact lever switch. A few things to remember when installing surface mounted point motors: 1) Make sure your track is secured to the baseboard. Hornby track pins are ideal for this purpose. This is especially important if you use the foam underlay. If you don't, it may move. 2) Common can be shared between multiple motors in DC, but must be present. Mine are fed from the 16vac supply on the back of my HM2000. Check also that the lug in the hole on the point motor housing is below the level of the top so that it slides in easily. /media/tinymce_upload/db6b5059e42530de19d07398e3d59206.png My diagram will have to be moderated, but it shows how I've wired mine, and I've had no problems other than motors not being aligned properly with the track.
