If you are 100% sure the alternator is good, then either the wiring or the battery are bad. If the battery has a dead cell it will not hold a charge. Disconnect the battery cables and clean the connections. Charge the battery with a battery charger, and then connect the cables. If the battery is over 3 years old, it is more than likely bad.
I would have the alternator tested. If the alternator is over charging the battery then it is just cooking it.
yes if one of the wires was getting an earth from the alternator cover or rubbing off the engine the battery light is really an alternator light warning you that the alternator is not charging the battery
Your battery is not charging due to a problem with the battery cables or a bad alternator.
That would tend to indicate that the alternator was not charging the battery for that interval.
You could have a bad battery, or you might find that your alternator is not charging. You can almost always get a local shop to put the meter on both battery and alternator to check the charging system.
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.
usualy if the alternator is not defective then its the battery. you should start by cleaning the battery post. then you could check the terminal wire that runs from the battery post to the alternator. if thats not it you should check the ground on the alternator.
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.

New batteries require charging before they are used. Try charging the battery with a home charger (dont let the alternator charge it as it will decrease the life of the alternator) and give it a try.
