Richard - just had a thought with checking voltage - how about adding a load (e.g. a car bulb(s)) equivelent to the systems output at the test meter prods ?

This would tend to show any dry or weak joints/connections.

As you say, the reading will be incorrect, but the main thing is that it is consistant all round the layout.

Welcome to MRF Suz - just a thought - are you using the Peco track cleaning rubber ? - if so it does tend to leave a slightly rubbery residue on the track after use which really needs to be cleaned off.

I'm sure that if you follow the sound advice already given by other members to will achieve good running.
