Two Planks Become One
Hi Ed. Thank you for your reply. That is a good question. But today Matt has come up with an idea, which I tried.I have desoldered both red wires to the points on the “ slave board “ connected the boards together, electronically,and no flashing on the handset. But, and a big but it is. What is the next step. When I mentioned the previous problem I had with the DPDT Slide switches to the supplier ( over the counter, face to face as it was) he said that it shouldn’t matter which way around the switches are facing. Best wishes Kevin

If you've disconnected one side of the feed to the points and there's no short, it sounds like the red and black are the wrong way round, probably on the slide switch, but we really need a picture.
The DPDT slide switches will work whichever way around they are, as long as they're wired up correctly.

So no bananas between the 2 boards? With 2 PCP units on the same bus? Yes/no and yes/no.
If not then that eliminates that. Back to the drawing board.
If you go over the track of the fiddle yard with the multimeter are there any issues?
If you connect a DC powerpack? ditto.
Are any of the points connected to a sllde switch? Ditto.
Does black on the scenic connect to black on the fiddle? Red to red?
Do they have the same polarity?
I think I would remove all the wiring, disassemble the track and start from scratch, testing as I went as recommended by others. Including all the points. Any stray wires underneath?
Just to make sure. When you connect the 2 boards with bananas there is a short? And when the fiddle is powered in isolation there is still a short?
If you haven't got the multimeter up and running yet you will be working in the dark. Although that light circuit you have will help. Not with polarity though unless it is an LED.

if you dont know some of the answers say i dont know
Hopefully Matt will contact you at some point to sort your photos

1) you have 2 boards Master (scenic) and slave (fiddleyard)
2) Master has a pcb. . . Slave doesn't
3) each board has 2 points placed toe to toe
4) both boards work ok independently but powering the slave from the master via banana plugs shows a fault
5) if you disconect the red wires from both points on the slave and power up the fault disapears
All correct ?
My next suggestion, get pen and paper and do the following
1) check that all four DPDT switches are fitted the same way round
2) Draw all four switches mark them Master 1 master 2 slave 1 and slave 2 (draw large so you can mark info around each one)
3) draw an arrow next to each switch showing the physical direction each switch faces ( all 4 the same way ? Or 2 left 2 right ?)
4) Now add in the wiring information showing where each coloured wire connects to each switch
Then we can move on throm there
Cheers

Is this what has happened? Would that explain it? Those with more expertise than me jump in. Now I know why I don't bother powering frogs by keeping them isolated but live.

If both boards work ok when powered separately, how could there be a problem with the point wiring when Kevin connects the boards together quest:
Am I missing something :???:

There could be serious consequences if you wired them like that.
Don't panic Captain Mannering, don't panic…
It's Multimeter time!!! Turn that ootoob off, it's mostly full of questionable or dubious advice meant IMO to deliberately mess up whatever you are doing. Project Binky and Martin excepted. Get down the shops and buy a new battery. Support the Chinese economy. Might help Hornby's QC issues.
Order a decent basic and fused DC controller, essential even if you are DCC. Better to wreck one of those than that Powercab which does not have any surge protection. Whatsoever. Nada. Zilch. Rien. Nichts. Nihil. Nowt.

Ed all we know at the moment is with the boards connected together there is a fault. If Kevin disconnects the red wires from both points on ONE board the fault disappears. I've asked Kevin to draw a diagram of the wiring of all the point switches and once we gave that I'll get Kevin to photograph it and then we will get some photos uploaded. Then it will be all heads together to see if we can find where the fault is ?
Cheers

Which red wires on what points quest:
Without a picture, we're all working in the dark exclam:

Hi Nigel What serious consequences? Wired like what? The YouTube polarity tester, worked for me before.Best wishes KevinHi Kevin,
