DCC shorts on reverse loops

[Wiredup]

I got a reverse loop in my layout thats giving me trouble. I'm using Digitrax reversing unit and MRC for my control system. Never had a problem on previous layouts, but for some reason this ones giving me a pain.

On the reversing block I have the insulated joiners as close to the turnouts as possible (using kato unitrack) and the unitrack switches are set to power diverting.

But for some reason, no matter how I adjust the sensitivity on the digitrax reserversing unit it keeps shorting out. Even when the loco is past the cars (metal wheels) are still going through. Seems odd... I double checked for connections where the insulated joiners might not even be doing their work, but no, it's still shorting out.....

I wonder if it's to do with the power routing of the turnout. At <!-- w --><a class="postlink" href="http://www.hotrak.ca">www.hotrak.ca</a><!-- w --> we use Digitrax equipment exclusively, but with insulated turnouts.

Do you have live frogs on the turnouts? Since the metal wheels on cars also short out, it sounds like a clearance problem in the frog allowing a wheel to bridge both rails rather than the reverser.
