Yes you are correct Kevin but just do as Matt has told you in the morning and see if there is still a short when the boards are connected.Hi Brian. But the illogical thing is black to red bus, that is why even this isn’t DC . But AC we have one red bus with all the red droppers going to the red bus . And all the black droppers going to the black bus. Best wishes Kevin
If there is no short we will all know straight away what the problem is

The layout has a trestle bridge over a modelled river, and the trestles were to support the bridge on the model, they stand all of 2" (50mm) high and are made of modelling wood from the pound shop.
Hope you've got your problem sorted out now,
Regards,

I have followed this thread somewhat from a distance and have come to realise that a certain amount of confusion arises when various topics are discussed inter-twined with each other.
The question of short circuits mixed with comments about trestles, scenery and old films has left me (and perhaps others) somewhat bamboozled.
Can I suggest that this thread simply concentrates (for now) on the question of the short circuits so that when someone asks a question and expects and answer (often just "yes" or "no") you simply give such an answer. There is no need to try to make a reply witty or amusing - your electrical issues are a serious matter for you and the community is trying to give you serious support. When asked for a "yes" or "no", just say "yes" or "no" please.
The recent run of posts asked whether you had sorted out the short circuits between the two boards and I must confess, despite a number of your replies, I am none the wiser.
If you are able, photos, diagrams and pictures often speak a thousand words. Try drawing a picture or diagram, photograph it and post the photo if that is the easiest way around.
If you are asked a question, please answer JUST that question. When the boards are running well, THEN we can start talking about tunnel mouths, scenery and all the other stuff.
There are number of people all trying to help but you need to help them to help you. We are all on your side here mate - I am sure that with some clear answers we can nail this and get you moving forward.
Kind regards

I have established that the current short circuit is at the rail gap between the baseboards and only occurs when the baseboards are connected. As far as diagrams or photos are concerned, I will take a photo of the underside of the baseboards and do a diagram, as best I can. Best wishes Kevin

You have 2 boards - Board A and Board B - never mind what's on them - they're just "boards" for now.
Board A runs perfectly with locos able to go everywhere and with points set in all directions.
Board B runs perfectly with locos able to go everywhere and with points set in all directions.
When you join Board A to Board B (with just 2 linking wires) you get a short circuit.
Is that correct - just "yes" or "no" please …………………………….

Ok first step I would try is as I mentioned. . . Switch over ONE end of the connecting leads and see what that does

When you stand at the "front" of the boards (not connected), which rail is connected to your red bus - the "front" rail or the "rear" rail ?
Is it the same on both boards - i.e. "front rail (let's say) red" and "rear rail" (let's say) black ?
Front or rear to red and the other to black isn't important but it must be the same on both boards.
Sorry, I crossed with Matt's post. Do what he suggests first …………………………….

Switching the feed wires just eliminates the obvious. . Then eat the banana. . . Then we move on to photos of the underside to see the wiring. . .
Black to the back right ? That works fine working round the outside of an oval . . . But when you work from the front of an oval on one side then go to an access hatch in the middle of the layout and work on the same principle on the back of the oval things go horribly wrong !
How do I know ? Been there done that now I use a wagon with red on one side, black on the other and trundle it round the track as I wire up, simple but it works :thumbs
Eliminate the simple then we can work on getting photos in here, but dont forget to eat that banana :cool wink

Is it possible that the blacks and the reds have inadvertently been interchanged (swapped), when the two planks were joined together?
That would cause a short circuit. :roll:
