Re: Reverse Loop Finder

Tom,
The problem occurs because locos in particular, as well as many passenger cars with lights will have electrical connections between the wheels and axles on the same side of the rails on the same or multiple trucks. This is done to aid power pick-up. When one of these multi-axle units spans across the gap where opposite voltage appears, it creates a short circuit.
