I'll certainly be careful with the remaining point to look at that. My general attitude will be to eliminate the small radius points. I've no problem at all with the medium radius.

Hi I was using the 15V DC output on a Hornby select controller to test the motors and to power the switching of points when I conducted running tests after track was laid.

Thanks to everyone for the suggestions. I have tried all of them including switching around the wiring in case I'd got it wrong. The net result was that I could not solve the problem until I removed the spring on the point. After I did this the point motor would throw both ways as you would expect as there is no spring to overcome. I have one more small radius point to fit on the layout. I'll post again if I get a problem with this one as well.

I'm having a bit of trouble with Peco code 100 small radius points. They are the electrofrog version with PL10 motors and PL13 frog polarity switches fitted. The motor is wired with the Peco harness and I have a Centre OFF SPDT switch to operate the point. The motors are attached directly to the points via a hole in the base board. The issue is that they will usually only throw one one way.The point will not throw to the branch direction. I have tried: Different motors with different points to see if there was a fault with any individual piece of equipment. All motors work individually and the same motors work perfectly with the medium radius points I have. A CDU to give a pulse boost to the throw action. The same result, the point will not throw to the branch direction. Alignment - I looked carefully at the alignment of the motor to the point but making adjustments makes no difference. Anything else I can try? Could it be the point blades are too stiff to move?
