Montague Posted January 20, 2015 Share Posted January 20, 2015 Electrics is not my strong point, to say the least. I'm trying to wire my Cobalt lever and Cobalt point motor. I have read and re-read the DCC Concepts manual, but on the pictures in the manual, the power pack has three contacts - right and left goes to the lever, a common from the lever goes to one contact on the point motor, and finally, a wire goes from another contact on the point motor back to a (common?) contact on the PSU. Unfortunately, I don't have a common/third contact on my PSU, so I don't know where to put the wire from the point motor that does not go to the lever?! Can anyone help?

I have just checked the DCC Concepts web site and I can see your problem. Their point motors work by reversing the polarity of the dc power supplied to them. You can do this using one set of lever contacts if you use their specially designed power supply which has three contacts whereas more traditional power supplies only have two sets of contacts. I presume this is what you have. You would need to use both sets of (three) switch contacts on the lever to achieve what you want to do with a more traditional power supply. According to the way I read their manual: Terminals 6 & 7 on the lever go to contacts 1 & 8 on the point motor. Terminals 5 & 8 on the lever go to one PSU terminal. Terminals 4 & 9 on the lever to the other PSU terminal. Link to post Share on other sites More sharing options...
