I have a 2.4 amp electrical drain on my battery when the car is not running
and the ignition is off, per tests at Sears showing my Diehard battery being
in good shape. There are no light bulbs on in the trunk, under the hood, in
the glovebox secretly burning. I know the car computer, clock and alarm all
draw some current when the ignition is off, but these would total far less
than 2.4 amps (which is running the car battery down). If there was a direct
short in some wiring, it would be far more than 2.4 volts and probably burn
the offending wire. Any ideas as to what might be causing this?

 

Larry,
Assuming that you have already used a multimeter to establish the current
draw (unless you are a good guesser and stated 2.4 amps off the top of your
head), you just remove and re-insert fuses in the panel until you find a
significant drop in current draw from the battery. When you find the
offending circuit, check the relays on the circuit (including the ones under
the dash) and the rest of the electrical control boxes on the line before
tracing wires - which the Bentley manual will help you with. Often times
the draw is caused by a stuck relay (such as the one that keeps the lights
on in the car for a while after the doors are closed).
Cheers!

It appears it was the car phone causing the problem.
