Hi. Can any one help a  railway novice. 
This is my first go at building a layout and its been a steep learning curve in many areas, planning, electrical, joinery etc
I'm running a DCC system with ip digital point motors run off a separate bus wire and alpha switch via a sniffer port.
I'm having an issue with a set of cross over points where the live frog on one point works on the cross over but doesn't work on the straight through line.. 
I've checked the frog wire and other wires. Remade one solder joint as I wasn't happy with it. I've adjusted the throw of the point thinking that it may not have thrown far enough to switch the frog. 
I'm at a loss to know what to do with it. My 2 other cross overs work fine and all the individual points function well. 

has Any one got any ideas ?

Hi Ian,
As you are using a separate bus for the motors, can you confirm where the frog wiring is connected?
Is it via the S2 L/C/R terminals on the Digital IP?

If so, can you check the continuity of the switch?
Disconnect all wiring from the s2 terminals and check for continuity between S2L and S2C in one postion and S2R and S2C in the other.

What system are you using for track power?

OK - thanks for that.
We have seen an odd motor or two where the internal track on the pcb has burnt out on a track/frog short - when running a 7A booster...…..

Check the S2 connections as above with a multimeter.

Mick I've checked the continuity between S2L and S2C in one postion and S2R and S2C and there is continuity through the ip switch which is I assume what you wanted me to check. Does that help.

Hi Ian,
Yes - if you have continuity between l-C and then R-C, the internal switch is working.
Check the wires connected to the L and R terminals - are they live to the respective rails?

Hi
Just to make sure. 
The two frogs on a crossover are not the same polarity

Hi Ian
i had a similar problem and I had forgotten to snip the two connections on the underside of the point. Once I did this it worked ok.
