Four Bridges

I'm using Gaugemaster PM20 motors throughout, except 1 which is a SEEP PM1 under the board.

On the crossing in question, one point has a PM20 and the other a PECO PL11 as I had this spare and it saved me buying another PM20.

Same principle applies. Try red to red and black to black or red to black, black to red. I believe green is the common wire on these motors.

I already tried both scenarios. Neither throw both points at the same time.

Are you using a capacitor discharge unit CDU?

[andy757]

Yes built into the panel. The motors throw perfectly when wired separately but not when linked together.

[Walkingthedog]

You must be doing something wrong, you’re not using the Peco CDU are you? I never had a problem throwing two sets of points.

[andy757]

Not a peco CDU as far as I know. I will try again tomorrow.

One possibility... I was using scraps of wire obtained free on my previous layout. I had an issue with point solenoids as they seemed a little weak. I found the issue as the points concerned had wires which were a bit thin to handle the current. (Old telephone cable or something similar). I doubled up each wire by using two and it was problem solved. The points threw well with or without using a CDU.
I only mention it incase it may be a possible solution. Could some wires be too thin to handle the current? Could a thicker wire only just be touching a terminal by a few strands etc.

Still no luck with wiring 2 points via 1 switch but I'll keep at it until I succeed

On a brighter note (no pun intended), I have now wired in 90% of the 12v lamps plus a simulated arc welder in one of the industrial buildings. The chap who made my point control panel also made me a lighting panel.

If I can capture all this on my camera, I'll post some shots.
