An ammeter shows current, and is not sensitive enough for small drains on the battery over a long period, whilst doing what I suggested, will give an instant reading on any juice being used that should'nt be.

I use both a voltmeter and ammeter to check if the alternator is working as it should, the output from the alternator should be around 13 to 13.5 volts, amps will depend on the regulator.
