Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
Is it charging, if not have you checked wiring to alternator.
have you checked the alternator??? that's the first thing that comes to my mind if your battery is being drained
Have the output of your alternator checked,it should put out 14.5 volt. Also check the battery connection to virify that they are clean.
have the alternator and the battery checked
Simple, have the alternator checked and if it is okay, check the alternator circuit to the battery
Your alternator could be bad have it checked this could also be that the car is getting the wrong amount of volts from the battery, either too much or too less
Probably loose drivebelt. or alternator belt of it is seperate.
There is no problem...the problem was the alternator. You have fixed the problem.
Disconnect it. let it cool and replace it. If you battery is boiling that is an indication the alternator is overcharging the battery. Have the alternator checked at any auto parts store.
Wires between Alternator and Battery, and between Alternator plug connector and fuse box etc.
Your alternator is defective and not recharging the battery. Have the alternator checked.
Get the alternator checked before your battery goes dead.
