Only professional carpenters can used hammers? Far more
complicated - requires far more knowledge - is using a cell phone or
Ipod. On the meter, select 20 VDC range (with power on). Touch
probes to wire contacts. Read numbers. Using it was not explained
because it is that easy.

That last post demonstrates why swapping parts also can lead to
confusion. Swapping parts can also cause other failures. Swapping
parts assumed the new part is known good. Shotgunning is performed
when all else has failed or everything else has been eliminated
(therefore the last part must have failed).

The meter is for people only smart enough to shop in Kmart - which
is why the meter is sold where hammers are also sold. If a meter is
too complex, then one has no business even removing screws from the
computer. Even that disk drive is more complex, easier to destroy and
more hazardous than a meter. Meter is used by high school science
students. The meter discovers in seconds what shotgunning can only
hope to accomplish in minutes.

As tjhat flow chart demonstrates, by replacing parts without
definitive answers, the repairman would have replaced most of the
computer and still not even know what the problem was. That is also
what shotgunning does. Meter should only be used by people who can
also use a hammer or who do junior high science.
