try playing with the battery cable connector. mine had a bad connection and it wouldn't turn over every once in a while. you might need new connectors
Take it to auto zone and have the battery and alternator checked out free.
If you have already checked the connections on the battery I would suggest testing the alternator and the battery. If the battery will not take a charge or the alternator will not give a charge you could have similar problems.
the vehicle needa a new voltage regulater,this should have been checked before battery and alternator as its the cheapest part to replace
the common cause why the light is on is that your alternator is not working well,try to have your alternator checked .may be the carbon brush is already worn out.
It sounds like you have a break in the wire which connects your alternator to your battery, get it checked out.
Is it charging, if not have you checked wiring to alternator.
have the alternator and the battery checked
Simple, have the alternator checked and if it is okay, check the alternator circuit to the battery
Probably loose drivebelt. or alternator belt of it is seperate.
There is no problem...the problem was the alternator. You have fixed the problem.
Check your battery post to make sure u have a good connection
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.
