Have you used a meter to determine if there is a short in the isolated siding?
Yes same source....I have not tried a meter yet
@turkey_hollow_rr posted:Are you saying that when the car straddles the isolator on the power rail that the power shorts and trips a breaker or fuse?
Or,
Are you saying that you see sparks when a car straddles the isolator?
Yes both....if i let it sit straddled is shorts - using z4000, voltage goes down red light on etc. when it rolls over wheels are sparking....just never seen a short be that dramatic.
@Danr posted:The only way you can create a short like this is to have a center rail and ground rail touching. Check your wiring. If this is two separate transformer, flip the wall plug over to get them in phase.
I agree I have to have something crossed. I do have a bus wire feeding 4-5 toggles I have to have inadvertanly switched something there...because this thing was working.
not a separate transformer.
It might be a few days before I can get back to it...I appreciate the input. I will let you know.
