[Healeys] Multimeter Question

[llennep at verizon.net]

Hello Listers,I am seeking to tap the knowledge of the list on this general auto matter.I bought a hot rod last year and from the get go I have had a battery drain.  If system is left on the batt will get too weak to start engine in a couple days or so.  Recently I have been chasing the problem in earnest.  I did find one issue and resolved that with the hope that the drain was fixed. No.  Still there.So yesterday I began preparing for the standard search method - pulling fuses one at a time and noting the drop in amps running through the system.  However I needed a dependable multimeter.  I have 3 but do not trust the amperage reading on any of them.  I secured a known good meter today and here is what I am observing.The reading starts out reading a few tenths amp fluctuating wildly and then drops to almost 0 in 2-3 seconds.  This happens time after time.  What is going on here?  Why is the meter behaving this way?Any help much appreciated.Keith
