[QUOTE="seewai, post: 622568, member: 11307"] I just googled "battery light turns on and off" and many many pages were displayed, I picked a couple of posts and they suggest the alternator. "the alternator could be producing too low of a voltage and this could cause your battery light. try testing the alternator output and see if it is varying too much. usually supposed to be arond 14.5 volts you could have a bad alternator or a bad voltage regulator. there is also the possibility of a bad battery but I would get them both tested. good luck and I hope I helped" "the battery light is never the battery it is the light that tells you the alternator isn't charging the battery it sounds like a loose belt to me as if it were the alternator the light wouldn't go back off now if it were a 1996 or newer car the alternator may be controlled by the computer as well NEVER DISCONECT THE BATTERY ON A RUNNING CAR IF THE ALTERNATOR WAS WORKING IT MITE NOT WORK NOW and it may deploy an airbag" "Suggest that your alternator is a b it sluggish,or your alternator belt needs tightening." etc etc....
