Reversed polari
Hi, My Frateschi Turntable, suitably chipped, has worked perfectly for yonks. I decided to change entry into layout, and re routed it, via point, suitably adapted, EG, with soldered wires, as per all the others. Point and track, work a treat, but when it enters tt, Short occurs, As , an aside, TT, on number 022, still runs perfectly. Not only, has the polarity reversed at TT, but also, on 3 tracks, at the far end, leading to Engine sheds. When testing with bulb, its fine on layout, up to TT, then lights up on other rail, on TT, and 3 loco sheds. The only thing that i have changed, is where TT, enters layout. Baffled. Help. john

Dont know a Frateschi Turntable but most turntables have a place where the polarity reverses perhaps you new entry road is just over the point of polarity change hence the short.

I would agree with Brian…..I would check the point where polarity changes.
If that doesnt provide the solution a before and after sketch map would help
Good luck
