Car saying service battery charging system /?

It could mean several things, but ultimately there is a problem somewhere in the electrical charging system. Either the battery is bad, the alternator is not charging, or possibly something as simple as a corroded connection bad enough for the system to see a voltage drop.

Could be a wiring problem.
Have you checked the wire from the alternator to the battery or starter, and is the alternator being entergized by the key switch ?

Have your charging system tested. The battery light is turned on when there is a charging system problem causing an over/under charge condition. You may possibly have an alternator problem. If the battery is not being charged properly, the computer will start shutting down electrical components for protection and to keep enough voltage supply to enable the vehicle to continue running

your car has an alternator that is supposed to charge the battery. The light comes on when it doesn't. Most likely your alternator needs to be fixed, though it could simply be a loose fan belt.

"Battery charge system" means "Alternator" and the associated wiring.

Charge the battery or jump start it. When the alternator dies, the car runs off the battery and drains it. Older batteries can recoup fast enough.

I drove Volvos for 17 years. Finally learned that a New battery had a short. Meanwhile, I'd changed out alternators. Switched it to a generator. It was a bad battery, from the get go. Just a thought.

you have a serious short somewhere that is dragging you battery down...parts houses will check your charging system free... hope this helps

A battery can read 12 volts yet be weak in cold cranking amps, try a jumpstart and if that works have your battery load tested. Im betting your gonna find the battery fails the load test, meaning it needs to be replaced..

Its the same system to the light. You could take the car to Sears or an other large auto parts store and ask them to check the chargeing system.They check it for free. Or if you have a volt meter, with the engine running check the volts at the battery. It should be from 12-14 volts. As long as it says 12.5 volts up to 14 volts then your alternator is chargeing and could be you battery is bad.
