Fishmanoz Posted April 30, 2012 Share Posted April 30, 2012 In fact, swap the latest decoder for one that works and put the working one in the new position wired to the new point motors. Does the old one work in the new position - if yes then your wiring is OK? Does it result in the new points motors now working - if yes then all your motor witring and installations are OK? Now how does the new one respond in the old location - if yes, you have a mystery to solve but if no then you have either a faulty R8247 or it is not programmed (then try to program it again on the programming track)?By doing this though, you should now have isolated where your problem is.

David55 Posted May 1, 2012 Author Share Posted May 1, 2012 Thank you gentlemen for both of your advise.Having played about for some while, I had a look at the other decoders and suddenly realised I'd given the decoder the wrong program number.It should have been 6 (points 21 - 24), I'd put in 21.

Fishmanoz Posted May 1, 2012 Share Posted May 1, 2012 Great to hear about someone who has their points working at last, it's usually only those with the really bad problems on here. Gives me some confidence I can do it too - soon. Link to comment Share on other sites More sharing options...

Victoria Vulture Posted May 7, 2012 Share Posted May 7, 2012 I have just finished building a shed layout with 12 sets of points all with gaugemaster seep pm2 motors and 4 R8247 point decoders, I have programmed them as in the manual but nothing works.I thought the point may be too tight a fit so took the point motor out and tried it on it's own, still nothing.where am I going wrong? as I have £160 worth of decoders and points that don't work.can anyone help? please???

poliss Posted May 7, 2012 Share Posted May 7, 2012 The wiring colours might be different. Hornby uses Black for the Common wire and at least one other company uses Green for the Common wire. Rog(RJ) will know.See http://www.freewebs.com/platelayer/tipsandwiringpage2.htm Link to comment Share on other sites More sharing options...
