To the Dojo, If we are to avoid ISC work as the hari-kari-like sentence it is, how can a non-ISC appliantologist like me keep up with ALL company service bulletins and updates for factory-created boo-boos? Could one of the certified Masters start a forum for such wisdom? I feel I should be practicing on refrigeration and circuit board-related repairs; junkers would be a good start, right? What method(s) do you guys use--junkers again, home study (which one)? What is a good home-study curriculum for electronics, or should I go to tech school (keep in mind I'm a working journeyman appliantologist)? What are some go-to tools for electronified appliances? Thanks in advance, Tyrus (aka RedToryTy)
