Sean,
You measure current by placing your meter in series with one of the ends
of what you want to measure. Take one end of a wire off a device that
you want to measure attach the other end to the device where the wire
came off and read the meter, on the amp scale. If you don't get a
reading or the meter seems to deflect to the left, reverse the leeds and
try again. Think of it as measuring what goes through a single wire, cut
the wire in half and put your meter in between. Never ever try to read
across a positive and negative while the meter is set for amperage, it
will blow your meter, ie + to - post of a battery.
