[sdiy] a little knowledge is a dangerous thing !

[Harry Bissell]

I used to work with a tech who would make resistance measurement charts to troubleshoot production units... compare
the bad one to a working one. He could fix about 95% of the units that way. The last 5% he could not make work at all.

I prefer to use a 'functional block' approach myself... what ~should~ it do... and what ~does~ it do... ?

That tech is now a real estate agent. (probably makes more money than me... :^)

True -- but it's quite clear that's not what he's doing, though.
