Hi
I've spent hours and hours exploring the variables on this and finally figured it out (at 4 am this morning). I'm using a tam valley dual frog juicer to switch polarity on a Peco crossing. Worked on a testbed, not when placed in final configuration on the layout. Sent it back to Tam Valley and he says it checked out. Worked on testbed, not on layout. You can imagine the words spoken. Hooked up a DCC specialties PSX and it worked... Finally figured out that I was using a SPROG 3 on the testbed and ESU Command Station on the layout. I think the Command Station battles with the Frog Juicer on the short and gives up.?
I'll run this by Duncan at Tam Valley, but interested if anyone has a solution for this?
I'd just use the PSX board, but I need an autoreverser as well...
