1997 Park Avenue. Battery slowly runs down over 72 hrs. Disconnected
neg cable, placing meter between cable and neg post. Pulled fuses one
at a time thinking I might see a change in current flow thus isolating
a bad circuit. Nothing! Anybody have an answer or suggestion on how
to expand search?
I hope you're not saying you have the original battery in that car. If
so, just change it and go away.
In a 97 Park Avenue the meter reading of "nothing" that you state is
wrong I believe. Maybe you just left out some details. Modern cars
always have some draw on the battery when the engine is shut down. It
can be substantial for a few seconds to thirty minutes until the
computer goes into sleep mode. Usually it's only a few seconds though.
You'd see 50ma or so in sleep mode, but it varies. So your numbers,
meter, and battery are suspect at this point.
