SOURCE: my jeep is running down the battery every 2-3 days

Hook your meter back up to battery, remove fuse to dome light and make sure every thing is off, check meter see if draw still there, then start pulling fuse out, mark them so you'll know where they go back to, keep pulling fuse and keep an eye on your meter as you pull one fuse at a time, till draw goes away.Good luck

SOURCE: Battery dies while sitting idle

Well it could be possible that you have a cell that is going bad.. This would cause battery to fade with little draw from onboard accessories (ie: clock, etc...) Why not spend a couple dollars and install battery isolation switch you can flip when vehicle is expected to sit for a duration... I know this doesnt solve the drain problem you have but could be a solution for not having to jumpstart it when you need to ude it..Good Luck

2003 nissan altima 2.5L 4 CYL would'nt w'out jump.replaced battery and car was fine for two days. On day 3 , after car was sitting for 15 hrs dead again!garage cant find whats drawing when car is off


Do you see a brake light on while driving? That could be a bad alternator.

Ask your garage to perform a parasitic draw test - you could do this with a multimeter, as well; it sounds like something is draining your battery while off - it could be any fuse and not obvious like with lights on/etc.

I would 95% positively guess this is the issue due to time frame. If the garage doesn't know what this is, take her somewhere that does. Shouldn't be costly, either.

Oil pressure sometimes reads pressure when motor off. sometimes it starts then a brand new battery became dead. COuld it be the oil pressure sensor? APpears to be intermittent.


You need to have a parasitic draw test performed on the vehicle to determine the source of the battery going dead. The oil pressure switch should not cause a dead battery. Something is drawing power that shouldn't be when the vehicle is turned off

Have an '85 XJ6. If it sits for a few days the battery is dead. Where do i start?


You first have to determine if it is a charging of the battery issue, or the battery itself, or if there is an unintended drain on the battery while sitting.
You can check if the alternator is charging good, by putting a voltmeter on the battery while engine is running. Voltmeter should read over 13 volts, somewhere between about 13.2 volts and tops about 14 volts, or just over. Anything less than 13 volts, and the alternator is not up to par, not charging the battery sufficiently.
If the battery is a little old, and beyond its warranty, it may just be too old to take a full charge, or it might have a dead cell. You can have the battery tested to see if it is still good.
If the alternator and battery are both good and working properly, you can check for an overnight drain with just a simple testlight. Everything in car should be off. Now take off the battery negative terminal and connect the testlight between the negative cable end and the battery negative post. If you have anything draining the battery while it sits, the testlight will light up brightly. If no light, or a very dim bulb, the system is good. A dim light would just be computer and clock memory, a very small draw, like milliamps, and should not be enough to run the battery down.
If you have a bright light on the tester, just start pulling fuses out one at a time, till light goes out. The circuit for the fuse that turned the testlight off is the problem circuit. Something on that circuit should be off and not drawing power, but it is.
Good luck.

94 grand cherokee baterry goes dead after sitting 5 days starter clicks and flashers flash. recharged battery will last another 5 days,


battery could be at fault or there is a draw in system that pulls down battery
have battery tested and leave it disconected for a few days then reconect to see if vehicle starts
if it does battery should be o.k. next is there any thing that stayes on (aftermarket stuff)
that may cause a draw on system if thats ok need to performed parasetic draw on system
hook up voltage meter between positive cable and meter
on 20 volt schale put red wire of meter to battery positive post black wire to red wire that was hook to battery voltaged should be minimal only to keep computers alive (clock - radio preset-etc etc)
if draw is high start removing fuses in system one at a time and check the voltage meter until it drops
you have now located the faulty cicuit that that fuse feeds start looking in those area
also feel starter selenoid and alternator at rear to see if they feel warm thet could be partly switch on
killing the battery over time
good luck

Brand new battery dying quickly on my 1999 jeep cherokee. draw was not bad, but it only lasts about 4-5 days without being driven before it dies out.


Never saw an ammeter that had a "normal" reading on the gauge face...You aren't reading the dash gauge are you? Normal procedure is to place an ammeter between the battery and either lead and read draw that way. Then remove each fuse till the draw diminishes substantially. An alternator can draw a bit but it should not be excessive.
Checking charging volts, the meter should not read below about 12.5V even with all accessories on and should not continue to drop regardless of running time. (accessories off reading should be between 13 and 14V).
Also have battery load tested if you haven't done that already just to make sure it is good (even when new) and make sure something simple like a visor mirror light or glove compartment light isn't on all the time.

Hi, my 2002 Dodge Dakota has been going dead lately and needs to be jump started. I have already replaced the battery to no avail. It usually goes dead after sitting for a few days. But the max battery...


It could very well be a defective battery, you could have 1 or more bad cells in the battery. A voltage regulator or an alternator. If it isn't one of those then there is something drawing power from somewhere that is causing it to go dead.

Battery goes dead when car sits 3-5 days 98 park ave


Obvious that something is drawing down the battery...Put a test light between the negative cable and the negative post of the battery (remove cable first) start pulling fuses till light goes out. That will tell you what system is drawing...you can then begin looking for the actual problem. If all fuses pulled and light remains on ,chances are you have an internal alternator problem.

2001 GMC Yukon Denali XL -intermittent dead battery


The wiper should not move regardless of battery change as the wiper switch should have isolated it.It seems to be the only ,as you say,strange thing and would be inclined to believe that that is the probable cause of your fault.Do like your testing method and hope you track the fault down.Good luck and happy new year.
