I wouldn't expect an inexpensive multimeter to make good current readings.
Better to use it for measuring voltage. Measure voltage directly at the
battery.
Engine off - should read about 12V.
Cranking - shouldn't go below 8V
Idling - about 13.8V
Now turn on the blower on high, headlamps on high, A/C and rear window
defogger. This should represent the full load on the alternator. Should be
able to keep 13.8V at idle though this is a pretty big load and may cause
the voltage to sag a bit. You may have to rev the engine a bit and see if
it will come back up to 13.8V.

Hope this helps
