Battery dies and there is no draw on it - 2005 Jeep Grand Cherokee

If it dies while the truck is sitting turned off, then you have an active circuit in the truck which should not be on (e.g. glove box or underhood light). To find the cause, an ammeter on one of the battery cables will show you a current drain and you can then pull fuses until the drain stops to find which circuit it is.
If the battery is draining while the truck is running, it is not charging properly. This usually means the battery is shot (even a new one - do a load test) or the alternator regulator is faulty or you have a wiring/grounding problem in the charging circuit.

check for a parasite drain the following links should help How To Perform Parasitic Draw Test EricTheCarGuy The BEST Way TO Perform Parasitic Draw Test How to Find Parasitic Battery Drain

you are going to have to check for a draw on the system and find what circuit the draw is on then check out that circuit and repair.

When does the battery die , over night , while driving the van ? Is the battery light lit on the dash when the van is running ? I'm just trying to find out when it dies . You could have one of two different problems , a charging problem ,which would more then likely be an alternator problem or if it dies overnight you would have a parasitic draw on the system draining the battery .!

Check the battery while the car is running. If the voltage isn't 14.3 or close the alternator is bad or going bad and not charging. Replace as needed.

There is a voltage draw from your battery while engine is not running.to prove this loose any one of your terminals.with all switches turned off including engine, disconnect and re-connect the loose terminal.if you get a spark then there is a voltage draw, find the wire and replace it

You have an electrical drain on the battery somewhere.

If I were diagnosing this issue at my shop, I'd use my multimeter to identify the baseline draw on the battery then start removing and replacing fuses one at a time and detailing the decrease in draw to identify what circuit is the source of the abnormal draw. That's the easy part...now tracking down what componet on the circuit is the culprit - that could take some time.

You could always install a battery quick disconnect into the vehicle.

have a "Draw" test on the battery. It may test OK, without a draw, but crash with a draw on it. That means it is a bad battery. If the battery is good, then you have a hot draw somewhere on the car draining the battery. good luck

with the battery fully charged try scraping the positive over the terminal on the battery and see if it sparks like a draw is sucking out amps if theres no draw on the battery it wont spark at all (good) if it sparks (bad) you have something grounded and killing your battery.. gl

YOU PROBALLY HAVE A NEGATIVE POWER DRAW TO CHECK THIS USE A TESTER LIGHT AND CLIP THE WIRE TO THE POSITIVE SIDE OF BATTERY AND TOUCH THE NEGATIVE BATTERY TERMINAL IF IT LIGHTS UP U HAVE A NEGATIVE POWER DRAW
