Thanks for accepting my membership.

I have a Christmas board, two ovals with a right- & left-hand #6 single crossover between the ovals.

One of the crossovers frogs behaves 50% correctly. When thrown in the diverging route, trains run through without issue. But when set for the straight through route, my locomotives short out on the frog. It appears that When thrown, the polarity is not being changed.

Can any one help me with determining which wire on the turnout might be mis-connected, or any other thoughts...

Thank you for your time...

Todd
