<div style="color:black;font:10pt arial">Michael would this buzzer sound (or a test light glow) from a completed circuit even though the current was a normal, very low few mA like is present in many of today's features in a car? - e.g. computer, clock etc<br>

<div>Another thick, similar to the bug light is to use an old "seat belt warning" buzzer rather than the lamp. That way the device doesn’t have to be in line of sight.

<div style="color:black;font-style:normal;font-weight:normal;font-stretch:normal;font-size:10pt;line-height:normal;font-family:arial;font-size-adjust:none">Hello Listers,<span></span>
<div>I am seeking to tap the knowledge of the list on this general auto matter.</div>
<div>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.</div>
<div>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.</div>
<div>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?</div>
<div>Any help much appreciated.</div>
