I agree with Bert I started as an apprentice at a manufacturing plant lots of trouble shooting and not just electrical; hydraulic, thermal, pressure interlocks as well as motor controls. Went to industrial construction/line work, sub stations, first gen mov programmable controls etc. 25 yrs later get steady work good pay doing troubleshooting/service work. Looking up at what I can see on the shelf above my computer I have 25 book ranging from electronics,machinist, hydro, hydraulic and instrumentation, pneumatics structural engineering, plumbing and carpentry. and of coarse several code books and motor and EE books. If you would not hire me I don't want to work for you anyway. Rod
