It might have something to do with the alternator.......... or maybe there is a short in the wiring
battery cable connection , dead battery
Check the battery it may be low or need replacement
There is a battery in this system that would be overdue for replacement in a 2004.
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. You may also have a battery drain (something that is staying on and killing the battery)

Bad Starter....
I would suspect one of two things. Either the replacement belt is not the correct size or the belt tensioner is bad. The squealing sounds like a loose belt which would also account for the battery light. possible bad battery causing the alternator to work too hard
Why would battery light come on then go off
It could
The battery currently in your Sansa will eventually die - it will no longer be able to hold a charge for a reasonable period of time, or at all. Once it dies, you would replace it with a replacement battery.
could be a bad alternator or battery
Dead battery? Battery cables in need of cleaning or replacement?
