Had used a Digitrax AR1 Auto Reverse Controller, prior to upgrading bus to 14 gauge from?16 gauge, on one reversing section and it worked fine.? Now it allows locos thru one end of the loop but shorts?the system at the other end.? Tried reversing the wiring into the reverser and the problem is solved at one end of the loop but not the other (ie the short is now at the other end of the loop).
I substituted a tam valley dual frog juicer, adjusted for reverse loops and it works fine.
Unfortunately, I have several of the Digitrax units and would prefer to get them working without buying another Tam Valley unit.
