If you are unsure of wiring generally you could get hold of a copy of "Wiring the Layout" by Peco, which you should be able to get from your local (if you have one) model shop.

It's quite a useful booklet - you can use the Triang point motors in the same way as the Peco ones shown.

Please ask away with any further questions.

I've just noticed on another thread that you are not in the UK - if you cannot get the booklet I'll get one for you & post it (I may even have one somewhere).
I'm in the Fatherland, so its a no go.
The HORNBY Point motors just have 3 holes in, and I don't want to ruin the motor, as they are the ones for the old points and signals.
So Any help would be great. maybe a scan of a wiring diagram would be OK.
But maybe the older catalogues might help...... will have to look tonight.

Hi Far Lands,

On the motor there are 3 holes, the middle one is the common, if you have the Hornby wiring you should have red/green/black, the black wire is common. When wired up if the point is giving the wrong direction just swap the red/green connections. Your problem maybe the electric supply and there are several methods to do it. I use the electric pencil type, it depends on the supply from your controller. Hornby will work ok of ac or dc, if you have an ac supply use that. Peco do a kit for the electric pencil, but I made my own with studs and an old pen. Hornby still look the same from years ago, I think it is the black switches for point control, they do other colours as well and you need the correct type or the motors will burn out.

About Bizerba's comment, it is the black Hornby 'passing contact' switch, part number R044, you need for switching the point motor. This allows just a short pulse through the coil to switch the point - if current is allowed to flow continuously the power supply will be overloaded and/or the point motor will overheat and be damaged, which is why you need this particular type of switch.
