There are a couple of possibilities.
   The current draw may be too low to show up on the 200 ma scale.  If
the reading is very  low, you can change the range to 20 ma or maybe
even 2 ma.
   There may be a fuse in the meter that is only for the current
ranges.  It may be burned out from some previous mishap; it happens
very easily.  Was the voltmeter on your dash working during your test.
 If the voltmeter has no battery of its own it should stop working
when you disconnect the battery.  If your multimeter conducts as it
should when set to a current range, the voltmeter should again start
to work when you put the multimeter in the circuit.  If possible try
these things and report back.
  Good luck,
Larry A.

I can rebuild engines fine, tune motorcycles, etc, etc, but when it comes to multimeters I am an idiot. I think I did it right, but want some backup on this. I put my MM between the + terminal on my new battery and the + cable. I then set my RadioShack MM to the notch marked 200 DCmA which also had a solid line beside it with 3 dots under it. I then took the reading, and it said 00.0 ??? I reversed the leads and it then said -00.0
