Check the exterior bed light to see if it is staying on but has a blown bulb. Also, you want to check the wiring on any devices you may have installed after you bought the truck to include alarms for shorts. If you had an alarm installed it is probably the alarm that is the problem.

Hi again just got a new battery, battery light is still on car is starting, but now whats the problem


The BATTERY light indicates that your battery is not getting charged. There could be several reasons for this most probably your alternator, which generates the current to charge the battery when the engine is running. If the new battery is not getting charged, it will eventually drain not start your car. To confirm that the battery is not getting charged and that is the reason for the BATTERY light, put a volt meter across the battery while the engine is running. It should read around 13 volts indicating that current is flowing into the battery. If it reads 11 volts or less, that means the batter is being drained and not charged. Then have your alternator checked.G

Battery on 06 silverado runs dead over a few days of not being used.


More than likely a parasitic drain.
Many times in courtesy system--Check after dark for any system lights burning, especially lighted mirrors if present.
If not found, drain test required.

I have a 2001 Honda Civic that would not crank and battery would not hold a charge, so I replaced the battery. It started up right away; then, the car sat for the weekend and when I went to start it this...


It could be a charging issue. But it could also be that something is draining the battery. To test the alternator you'll first have to charge the battery using a battery charger. Then follow this test.

Mitsubishi Diamante 2002 - slow battery drain when not running.


This problem may be a drain or a bad battery or alternator.

The first thing to do before going on trying to find the system that is draining the battery would be to have the battery tested and charging system tested.

A weak battery will seem ok after the car is jumped or will barely start the car and the alternator will charge it even though the alternator is overworking due to weak battery and during the day or when car does not sit long it will seem ok. then when car sits overnight or a few days battery will weaken on its own, making it look like a drain,

so first step is battery test and alternator/charging system test.

Battery keeps draining even after replacing alternator on 94 gcl 5.2 any ideas


Try this, disconnect the alternator and see if it still drains the alternator, you say new but i know it is rebuilt, and some rebuilders do a terrible job, this is esp true of the so called discount auto parts stores (that is a joke as they often charge more than a dealer) such as O'reilly and others. Buy a Mopar rebuilt if the alternator turns out to be the source of the battery draw down. Also make sure no light inside the truck are on like sun visor lights and so on. Have the battery tested shorted cells cause a draw and will kill the battery overnight, don't over testing new parts as they can be bad, found this out the hard way early in my mechanical career.

1998 Saturn SC2. For the last couple month sometimes my car won't start. I'll turn the key and get a whimper then nothing. If I then manually lock and unlock the car then it eventually starts. ...


There are many problems that could cause this issue. Your electrical system might have a drain somewhere -- maybe your alarm is malfunctioning (if you have one), or maybe a wire in the engine has somehow become damaged, grounding the system and discharging your batter at a slow rate. If your battery has been completely discharged before (completely dead) it might not be holding a charge like it should. Your alternator might not be charging the batter like it should while you drive, causing your battery to drain constantly and never recharge automatically like it's supposed to. It could be something more complex in your car's computer or electrical system.
The easiest way to check this is to go to a mechanic with an electrical system checker. Sears Auto Canter has all of the equipment, and charges a reasonable rate for checking your electrical system. Their equipment checks, no only the battery, but the whole electrical system for power drains, and the effectiveness of your alternator. If there is a power drain, Sears Auto can find it -- and they can help replace what is broken. They can also check the health of your battery itself (if it is not holding a charge, you can get a new one there). If it is not that, at least you have eliminated one possible cause.
If the car will start when jumped, it is most likely an issue with which Sears can help. If the car is still not working when attached to another car's battery or a jumper battery, then the problem is a bit more serious. In this case, a professional mechanic can inspect the car and find the issue, or at least give you a cost estimate, so you know if it is worth fixing.

Charging stystem seems to be working..... But when ever the miss's gets inthe car to go to work,she will get 10 miles and the battery light will start flashing,then get solid and she will lose the head...


When this happens, are the gauges dropping or not working properly or at all? Check the alternator. May not be charging so everything is running off the battery. The battery is used mostly for starting, but the alternator recharges the battery, so if after driving for a short while, and alternator not charging, everything electrical will drain the battery. You can sometimes drive the car for a while when this happens, or if the alternator goes out completely, the car will not run at all.

Kia rio 02 died while driving down highway


The battery is only use to start the car, once the car is moving the alternator takes over and charges the battery. I sounds like the alternator is bad. You take the alternator to Napa, Auto Zone or Advance auto part and have them check it for you.
