Atlas #6 switches short - Not DCC Friendly?

[jonyb]

Evidently..... Or does DCC have anything to do with it?
I'm using some older brass #6 turnouts, and I guess they don't have insulated frogs (still new to me). When the trucks cross over, the controller shows a short. I've cut the rails back and sanded them down with a Dremel, but it doesn't seem to be going away.
Ive looked over this: http://www.wiringfordcc.com/switches.htm
It's all Greek.
Any suggestions, other than pull it all out and sell it?

See where the two rails come into the frog and end up in a plastic point? That is probably where you are getting the short. The wheels on the engineer's side of the loco in your photo are probably wide enough to cover the tapered end of that rail and touch the other rail which is opposite polarity. The easiest solution might be to paint the railheads 1/4" or so back from the frog. It won't be a permanent solution but should take care of the shorting.

If it is not that, it is where the wheels exit the frog and the back of the wheel is touching the opposite rail. You should check the gauge of the wheels and track gauge through the switch as well.
