Dead Battery

99 Jeep Grand Cherokee limited - new battery, new Altanator. If I don't start the car for 1 day I get. Dead battery no clicks. I see a red light on on the set panel on the driver door. Any ideas?

First things first, if you have a multi meter, or can borrow one from a place like autozone, test the battery and alternator.

If that eliminates the battery and alternator you may have a different issue. I've drained a battery in my car just accidentally leaving an overhead light on overnight.

New does mean functioning properly, the first thing to do is have the alternator and battery Load Tested at an auto parts store or repair shop. The starting and charging wire circuits should be inspected and tested for loose, damaged, or corroded connections and wires.

Basic troubleshooting suggests that there is a parasitic voltage drain due to a switch malfunction, electrical circuit malfunction, or a short circuit from damaged wiring.

after driving ,shut off and read batt volts. should be 12 to13.
restart,should be 14 +. if so its charging.


pull headlites while reading. volts dip and come back up. its charging..
.
shut off, unhook one batt cable. read leakage current with doors closed, all lights off.


should be less than 1oo ma,1/10 amp or lower. if it is, batt is bad,wont hold charge.
if its higher you have leakage and you pull fuses till it goes away.


i havnt read mine lately but i think its less than 20 ma. ill check soon or someone jump in...
my hummer is 110 ma but jeep is lower...

Inspect power cable in door hinge jamb, open rubber boot, repair all broken wires.

The SET button is hint of a broken wire or wires, from cable flexing.
