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.

My 98 lumina has a constant power draw from somewhere. I just replace the battery and had the alt tested (it was good). I have to jump the dang thing every morning but if I drive it enough during the day...


The alternator may charge fine but could drain the battery through a bad diode,have you checked the alt for a bad diode?Disconnect the battery positive cable.Put a regular 12v test light between the battery positive post and the positive battery cable.If the test light is bright you do have a drain,if dim it is OK.A dim light may mean the drain is internal in the battery.If you do have a bright light remove a fuse ,one at a time from the fuse box until the light goes dim.Once dim you have identified the bad circuit.If removing all fuses do not dim the light,disconnect the alt charging wire at the alt,if that dims the light,then you do have a bad diode.DO NOT create a drain(bright light) when checking for the drain by turning on the key or opening a door/trunk etc.
Also,do an overnight battery check by disconnecting the battery overnight,if things are fine the next morning after the battery was disconnected then it is a drain in the vehicle,if the battery is dead even after being disconnected overnight,,then the battery is bad.

My car need's a jump ever morning , when I come down it's dead but will stay started once it's jumped please help going crazyyyyyyyyyyyyy.


First have your battery load tested, and your alternator checked for proper charging amperage. If that is ok then you have what is called a parasitic drain that is draining your battery overnight. A parasitic drain test will need to be ran and repairs made.

Good luck. i hope this helps.

There is a strong possibility that you may have what is called a parasitic drain on your battery. Which simply means that there is something running in the background that is pulling a load on your battery. These kinds of drains can extremely hard to find. To help you determine of you have a parasitic drain you will need a multimeter. If you do not have one I would recommend taking your vehicle to a trusted automotive service center. Call then first to determine what they charge per hour for diagnostics. usually will be about 1 to 2 hours diagnostics time.
