I am working on a chinese pignose G40-V, a real piece o'crap. Blows fuse, variac shows dead short. I systematically lift everything from the ss ps board until nothing but the PT secondary is connected. Still dead short. Nothing on the simple board looks shorted, can find no path to ground with ohmmeter. Board ground is also now lifted. Disconnect one side of secondary and read 355 vac. Hook it back up, dead short.
I'm thinking PT, but I don't understand why? Anyone?
