[DML] power drains....



Hey Group,
 
I have had a mysterious power drain this summer and I finally had some time  
to tackle it.  I hooked up my meter and found a 0.05A draw when the car was  
shut down and the doors closed.  I found that my Lockzilla was drawing  about 
0.014A (is that normal? I know it draws SOME), there was a fluctuation  between 
0.000 and 0.001 that I could not trace (probably the digital MM  quantizing 
the imperfections in the leads), and the remainder was in the  door buzzer/horn 
circuit.  I found that my horn was not working, so I  unplugged all the wires 
on the horns and put them back on.  The horns  worked again and the draw 
disappeared.
 
What was happening?  This makes no sense to me!
 
I had also noticed a high-pitched, faint whining sound from the door buzzer  
sometimes even though my wires for the buzzer are removed from the door switch 
 and tucked away so they aren't touching.  After putting the wires back  onto 
the horns,  this sound appears to have stopped as well.  I  had previously 
removed the harness from the buzzer box and cleaned the  connections, which had 
no effect on the whining or the power draw.
 
I also think my battery is fried.  It is a year old, however it left  my 
stranded today and I needed a jump.  The alt puts out 14.3V, and the  battery 
registered 12.5V before I tried to start the car.  It cranked about  4 times then 
slowed until it would not crank.  The battery now reads  12.2V.  Does that 
mean it cannot handle a load, even though there is enough  voltage?  It's on a 
trickle charger now and I will get it tested  tomorrow.
 
Any thoughts on these events?
