    I have a similar problem with my 2005 Cavalier. The battery drains, the car jump starts and runs, but the battery doesn't charge. The alternator has been checked, changed, and rechecked, and I am now moving on to the third battery. I've taken it to GM a few times, my regular mechanic, and an auto electronic specialist and keep getting the same results: something is causing a drain or the battery has an internal fault. Either way, no one has been able to isolate the problem. The factory-installed radio has been tested (disconnected for several
    months) and ruled out, the cabin/trunk lights have been checked and are
    turning off as they are supposed to. Anyone have an suggestions as to what might cause this type of drain and lead to chronic battery death?
    Thanks

    I also have a 1992 Corvette that is having the exact problem. The car was rear-ended and after the car was repaired is when I started having problems. I have noticed that after washing the car my interior lights come on and do not go off until the car has dried out completely. The stereo system is on a completely different line and is not active but the battery still drains. The short during the washing was never able to be traced. I can take the fuse out for the lights but still get battery drain. The battery was replaced with no change.

This may be over-simplified, but to find the battery drain: Remove the positive battery cable from the battery and insert an ammeter in series beween battery and cable. If something is draining the battery, it will show on the ammeter. Remove fuses one-by-one until you see a substantial reduction in the ammeter reading. That will pinpoint the circuit that is draining the battery. Then troubleshoot until you find the faulty component, wiring harness, etc. Remember there will always be a little bit of drain because of ECM, BCM, radio memory and stuff like that.

How do you tell if it needs charged or not?


Hi Kelly, A fully charged battery is 12.4 to 12.6. and when the motors running it's 14.3 to 14.6... Three reasons your battery is flat (isn't charging), You have a faulty battery, A power drain or you have a faulty alternator... Clean your battery terminals and If you don't have a multimeter then Try jump starting your flat battery and driving your car for at least ten minutes then turned the motor off and try starting it WITHOUT jump start, If the battery's still flat then it's the battery, If your car starts straight away but won't start the next day then you have a power drain... If you jump start your flat battery and go for a ten minute drive but during that drive the motor dies without turning off the key then it's the alternator....
A mechanic or an auto electrician can usually test Free of charge if you can get it there....CHEERS..

My dash lights go dim at night


Have you tried adjusted the dimmer switch??Some other things to check are your grounds and the charging system.The ground between the engine block and firewall/chassis is the ground for the interior & exterior lights so make sure its tight and corrosion free.
The next thing you should do is conduct a full charging system test. Here’s how to do your own.
Connect a digital volt meter to the battery terminals. A fully charged battery should read about 12.7-volts. Start the engine. The reading should jump to around 13.5 volts. Leave the engine running and turn the blower motor to HIGH. The reading should dip down and then rebound back to 13.5 or more volts. Leave the blower on and turn on the headlights. It’ll dip again and rebound. Then turn on the rear defroster grid. Next, sit and watch the meter for about 10 minutes with the engine running and all those accessories on full blast. If the voltage stays the same at 13.5 or higher, the charging system is fine. A weak alternator will start pulling the voltage down in small increments because it can’t keep up with the electrical drain.

2003 vectra 3.2 litre v6 not starting thought battery was flat as not driven for some time jump started it and drove fine.next day same thing had to jump start only drove for 5 min or so then the day after...


you need to check the alternator charge rate as this is the sort of problems associated with a low charge rate , unfourtunately you will need the engine running to do this so get a voltmeter ready for when you jump start the engine and read across battery terminals if reads below 13 volts the alternator needs replacing ,check that the drive belt is tensioned correctly as this would make alternator give low charge,also will need the OBD codes reading after all this going on , the engine doesnt need to be running for this just ignition on ,will give codes for sensor/switch which might be out because of the starting/running problems

Battery Drain


It sounds like an Alternator problem.
Remember the Battery only Starts the vehicle and runs nominal operations. The Alternator actually provides the electricity to run the Engine operations. With that being said: Start the vehicle, jump start it if you have to. Remove the Negative Cable from the Battery or remove the jumper cables. If the Engine dies after doing this, the Alternaotr is bad and needs to be replaced. When the Alternator begins to die, it starts draining the Battery. During normal operation it is the Alternator that sends a small trickle charge back to the Battery keeping it charged-up.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Won't start. Turned over then stopped turing over.


If you tried starting it too long you discharged your battery and either need to let it rest a few minutes get a jump or charge it. If its not starting then no use draining the battery it has other issues keeping it from starting right up. Id need more info to help with that. Could be any number of things.

Removed the positve and negative charge of battery for 10 minutes then, plug it back the positive first then negative charge and the last step you do is to start the engine. This steps is to clear tcs off, slip and awd lights.
