Battery light on means there is an issue with the battery, alternator or wiring. Measure with a DC voltmeter the voltage at the battery with the engine running. This voltage should be around 14.0 volts plus or minus .6 volts or so. If it is lower than 13 that tells me the alternator is not charging the battery. It could be an issue with the wiring that runs from the alternator to the battery or possibly a fuse or fusible link is bad.

You need to check the volts at the battery and the alternator with everything off in the car put the volt meter on the battery and have someone start the car your reading should be between 13.5 to 14.4 volts then you will need the check the voltage at the alternator that should be about 14 to 15 volts, if your voltage is higher at the alternator and lower at the battery then its possible cause will be bad wiring from the alternator to the battery. the light will come on if the volts drop to about 10 volts..
