Recently working on snow plows has reminded me of the knowledge gap
modern technology has created. Electrical schematics are as readable
as street signs to me but alien hieroglyphics to the plow owner.

I went on a service call once, in a different lifetime...

For a GM plant, 70 mi drive one way. Problem, printer doesn't
work. Powers up okay but won't print anything. We were GE repair for
much of the western portion of the state.

As I was coming into the open office area and still 20 feet away I
could see the RS232 cable for the printer disconnected and on the
floor. That's all it was. Plugged the cable back in and they were
printing again. The department was labeled as engineering too

Some of us see problems readily. Others just see equipment that doesn't
work...


I couldn't use my networked LASER printer after a brief power
outage. The damned thing had changed it's address on the network when it
rebooted. It had been through dozens of power outages, but that time it
incremented its address by one digit.
IT dept gave up on wireless network printer (Brother HL-5370DW) and
ran cable - no more problems.
