I have just bought my first set of switches, mth realtrax O31 powered left & right. when I run my weaver 2-8-0 to take the right turnout, half way through the switch sparks fly and trips the breaker on my 750 power brick. the 2-8-0 goes through the lefthand switch fine, my lionel 2-6-0, my weaver GP38-2, my lionel trainmaster all have no problems with the righthand switch.
I also did run it the other way, taking the lefthand switch first and coming out on the righthand and no problems, no sparks, no tripped breaker.
anyone have any Idea'a on what might be the problem.
