Funny that was never on any service literature or diagnostic procedure
documentation I ever read. Nor would I have ever made it my own
practice as a first step thinking back 30 through 30 years.

But then again this is an internationally mirrored forum so I don't
really try to pawn off my particular service procedures as the gospel
where the diagnostics flow chart may be much different in certain
regions of the globe.



I have hooked things up with isolation and later found things like a motor short.
Works fine with the transformer.

I didn't always first check the customers explanation and plug something
in right away before doing anything, but I do it now.
