To test the current draw, push the black lead into the COM socket of your multimeter and the red lead into the AMP socket. Set the scale to amps.
You'll need to disconnect the negative terminal of the battery and then put the meter in series with the battery i.e. black meter lead on the negative terminal and red lead on the negative lead of the battery. With the tracker on, you'll see how much current it's drawing on the meter. 50 milliamps will show as 0.050.
NB! Don't whatever you do try to start the bike with the meter in series; they're usually only rated for 10A max and the heavy current for the starter will fry it
I think the 1997 Monster still used the single phase alternator. I don't know what the expected DC voltage output of a healthy example should be but I think the AC output should be around 30v at idle, 70v at 3000 rpm and 140v at 6000 rpm (Haynes manual?).
This is a useful source of reference for the charging system:
