Re: Something went Bad Wrong!

the 140 vac  is most likely the results of the transformer adding the
primary and secondary windings due to the short in the wires..
ie..   140 total - 16.5 secondary  = 123.5 vac  house voltage

I think  they call that an autotransformer  where the primary coil  adds to
the secondary to give a higher voltage output..
