electronics, electricity, probably don't read.
I think I have a short, but I'm not sure where.
transformer runs off of mains: line wired to power switch to fuse to one side of the primary. other side of primary to neutral.
The short occurs when the unit is plugged in, but not switched on.
Current flows through the transformer, making it hot, but is low enough not to blow the fuse.
Chassis ground is hooked to the center tap of the secondary.
No conductors seem to be touching the chassis, except those that are supposed to be at ground.
The unit works when switched on, but there is a power sag, probably because of the short.
I am puzzled. The only path from line to neutral seems to be though the transformer, and having the switch off should keep that circuit open....
