Short circuit

[deltanw12]

I have wired the shown track plan but get a short circuit when switching power on. Have double checked all wiring and track for any problems, so is the actual layout of the track an issue?

Any advice will be appreciated.

What sort of track and points are you using? An obvious first question is did use use insulated track joiners at the appropriate places especially at the cross over?

[deltanw12]

 Hornby set track with insulfrog points and clips on frogs.

[Imustbemadatmyage]

Clips on frogs just make the points live in both directions.  You still need insulated joiners on both inner frog line, together with additional feeds beyond the insulation and, perhaps, frog polarity changing. All the clips do is to distribute the power to both lines at once, rather than relying on blade contact. Draw your track plan in two colours,  one positive and one negative.  You will then see where the problems are.

Sorry, should have said this is DCC.

You need to show on the plan where you have placed track feeds and where you have installed insulated rail joiners.

 

without this information we can see what is feeding where and where the potential short is coming from

to the best on my knowledge the frog clips should only be as shown in orange

If you have put any clips as shown in red then a short will happen

 

 

the layout plan should not be the reason for a short IE no return loops or triangles

 

are you using multiple droppers (power feeds) & a track bus

If you are the disconnect(at the track bus end) the droppers 1 at a time & check for shorts after you disconnect a dropper

When the short goes away check to see if that wire goes to the correct rail 

 

Hope this helps
