test the voltage on the battery first, then on the alternator. If its good then it could just be the diode in the alternator. I would suggest you replace it becuase eventually your alternator will die and the battery will not get charged leaving you stranded somewhere. It is possible to just be a battery but you wont know unless you have the battery tested. check the voltage on the battery and the alternator before you do anything else.
have you tryed to disconnect the battery cables it would be the positive one it reprograms the wireing.
no it doesnt
When this light stays on, it is telling you the system is not charging. Possible bad alternator, battery, or loose or disconnected wire.
If it stays on there is a problem with the charging system. Most likely a defective alternator.
The light switch could be bad. More than likely there is a short in the instrument panel cluster or a bad ground.
If your engine is running , and the battery light comes on , that indicates that your battery is not being charged
The battery light stays on when the alternator is over or under charging.

The battery light stays on when the alternator is over or under charging. The red brake light stays on when the parking brake is set or the fluid is low. The abs light stays on when the abs computer detects a malfunction and sets a code.
