Herc: what is probably happening is that the two rails that come into the frog from the far end are exposed and there are wheels that are wide enough to touch both of them at the same time. If there is power coming from the far end of the frog then you can get a short. I get the same thing sometimes in HO. The solutions are to either replace all your wheelsets with very narrow ones or to put gaps in the rails beyond the frog so that only the one rail is live at a time. Some modellers will put a bit of insulating material (paint, nail polish) over the bits of rail that show in the frogs.
It's quite possible that you have some flanges that are deeper than Peco expected, especially if you have older equipment. You can also get a bump if the gauge is too narrow -- use your calipers on the back-to-back of the wheels and the distance between the guard rails on the switch.

In model railroading, there are between six and two hundred ways of performing a given task.
Most modellers can get two of them to work.
