The battery light is supposed to be off if it is on that means something is wrong with the charging system most likely cause alternator is not charging.

Check the alternator voltage. Do this with a volt meter connected to the battery terminals with engine running. The voltage should be in the 13.8 to 14.6 range. If it is much lower than 13.8 there is a problem with the alternator or associated wiring.
