Where do you get these CarL?

If you are using anything other than rosin flux or rosin flux core solder then residual flux can cause a weak short.  Non-rosin flux is usually a weak acid flux which is conductive if there is any medium like water or something similar.  Rosin based flux does not conduct.  The primary advantage of the newer kind of flux is that it is easy to clean.  Cleaning rosin flux requires a strong solvent.

Sometimes when you cut the copper you can leave a tiny sliver that will also cause a short.

I didn’t think Fast Tracks supplied double sided ties.

Our club used double sided for a short while years ago. We had considerable leakage between the top and bottom after we ballasted.

We then slotted the bottom below the top - a little better.

Then we slotted just below the rails - a little better still.

Then used a soldering iron to heat and peel the foil from the bottom of the ties - problem solved.

Hope you haven’t got your turnouts glued down.

Brent, Chris is probably correct about the flux.

The problem is a path from the top copper of one rail to the bottom copper of the tie strip and back to the other isolated top copper.

I always cut gaps on the bottom side of the ties to avoid that problem in the future from ballast or anything else after installation.

Had the same issue, for me it was flux residue. Had to give them a bubble bath to get ride of the residue.

I have not done any ballasting. I am intrigued by the flux issue. I had one turnout that was bad enough even after cutting gaps on the back of the ties I ended up giving up. I will try “bathing” the turnouts from now on. The current turnout that prompted this issue is a curved one that I built specifically for this location and not using a Fast Tracks gig, although I used the same construction technique. I would prefer not to have to tear it out so I will try to clean it in place the best I can and see if that resolves it.

I recently started wiring my first section of a large layout and am using a short detection beeper, built like the one described on the wiringforDCC website.  I noticed a couple times the beeper reacting as I attached feeders located near some turnouts.  I checked the track with my ohm meter and am detecting a small amount of resistance between opposite rails stemming from some of my Fast Track turnouts.  I have double and triple checked my isolation cuts on the frog and printed circuit board ties and everything appears ok.  When hooked up to the NCE DCC system, everything appears to work ok. 

My question is, shouldn't there be zero resistance between two opposite rails?  Secondly, could this pose any issues down the road?

Thank you i will try them
