Battery going dead!
88 Cherokee
4.0 IL 6
Auto trans.
High miles - 300,000 +
Always been dependable!
I haven't been using the jeep very much do to illness here and don't need
both vehicles. This ones not the economy king so it sits.
After a couple of days the battery runs down.
So far I have removed the dome light thinking we might be leaving the door
ajar or neighbor kid might be looking for change again, no help.
Removed the light bulb in the glove box, still no help.
I have removed the fuse for the clock and still have the draw on
the battery.
Checked draw with digital VOM, I have a 280mA draw on battery, enough to
light a test probe light when in series with the neg. cable from the
battery.
It is not a problem with the battery because I have switched
it out with the battery from the other car and it is drawn down.
When I charge the jeep battery, and load test, the battery shows to be ok.
Looking at the wiring diagram I don't see any other possible draw with the
key out of the ignition switch.
I haven't added any accessories that would be a direct draw on the
battery.
What am I missing, other than a sence of humor right now. What could be
drawing 280mA all the time? TIA, Open to all suggestions.

Re: Battery going dead!
The radio and engine computer both keep a small drain going, I'm not
sure if they'd total over a quarter-amp as your draw is but maybe.

Re: Battery going dead!
You are correct... 280mA is much too high a standby current. If you
have monitored the current after each fuse has been removed with no
current reduction... you might try removing the "BATT" connection to
the alternator. Maybe you have a leaky diode in the rectifier pack.
Just a thought...
