Two Planks Become One

Ok Kevin but when you connect them does one go through a 180% turn to conect to the other ? Instand reverse wiring
Are there points on both boards ?  If so do the red and black wires go to the same contact on your DPDT switches ?

I.E. board A red goes to contact 2 black goes to contact 4. . . Board B red goes to contact 2 black to contact 4 ?

Or on one board is it  Red 2 Black 4 but the other board Red 4 Black 2 ?  Doesn't matter on individual boards but soon as you connect… 

I'ts things like this we need to work through slowly to find a cure. Let me know when you have done step one. . Eat the bana. . . No thats step 2 :roll:

I'm trying to figure out what someone has done with the lighting and power wires on an old mainline diesel using multi coloured telephone wires so I have multi coloured spots before me eyes.  Red and black is easy peezy !!! :shock:


Cheers Matt

Hi Max.  Thank you again. Not a “ Buckley’s “ . My buses go from end to end on opposite sides of the baseboard.I really do appreciate all the help and messages that I am getting. But I just cannot figure it out.
Best wishes Kevin 

Thats where my and Peters thoughts are I think Max  :thumbs

One step at a time mate, try reversing those wires and apply power and tell us what happens  :thumbs

Hi Matt.  Thank you again. I had thought of that myself ( changing over the Red and Black Wires  And when I swapped the wires, “ Crash,Bang, Wallop “ It didn’t like that at all. This may be incorrect? But my two independent bus wires go from end to end and at each end there is a staple banged into baseboard to support them. Soldered to the Red bus is a red ( Red Jumper) with the famous banana plug , likewise goes for the black. On the other board is a similar arrangement, but with matching sockets.

So when you switched the wires round did your controller show the same fault ?

I think to help everyone Kevin some photos of this wiring under the boards may well help especially these what you call bananas

Hi Matt. Yes, as far as I can remember. Best wishes Kevin 

Do you have points with DPDT switches on both boards ?

Hi Matt. Yes.  Kevin 

Ok, when your up to it upend both boards, and look at the wiring to the switches on each board, Do the red wires go to the same contacts on all switches on  both boards ? ( same thing for black wires)  At the same time take a few photos of both boards underneath, zoomed out and if possible zoomed in on the points/ switch wiring. I know this may be awkward if the switches are mounted on top of the boards with wires going through from underneath but pictures will help a lot.  if your around tomorrow we can work on uploading them here  :thumbs
Cheers

Don't get hung up on the bus wires Kevin.  It's the connections from the rails to them that matters.  If the rear rail on both boards is designated "black", then do all the rear rails have black droppers connecting to the black bus - and visa versa for the red "rail/droppers".

It doesn't matter two hoots where the bus wires are - front or back - it does matter which rail (on the track) is "black" and which is "red" and that all the connections thereto are the right "colour" and from the corresponding bus.

Hi Petermac. Thank you. In a short while I am going to take some photos of the wiring. Best wishes Kevin

As would a faulty banana. That one can get a bit slippery.

Edit: Forget that, a Banana plug only has one wire :oops:
 

Hi Nigel. Thank you. Brian has asked me “ what is a banana plug? Well of course I know how to use it and what it looks like, but, I don’t know how to answer the question. Would you please explain to Brian what one is.   Best wishes Kevin 

Banana plug  

So Kevin, I am assuming you wired board A like with red & black busses to banana plugs  & board B also the same way to banana sockets when resting against the wall ? Correct ?
Then when you turn the boards so B meets A, then of course there will be a short circuit  !!

Eloquently put!!  With an excellent diagram!!

Michael

Of course a short circuit will not show up until you run a loco across the baseboard joins.
