I have a 2004 polaris sportsman 600 and I have noticed that the battery light started flashing the last time I used it. It seemed to do this only when an electric load was put on it such as the lights or electric cooling fan. Is this an indication that my battery needs to be replaced or do I have a charging problem??

 

could be either. can you check the voltage output while the bike is running and reved up say around 3,000 rpms'? should be putting out 13+ volts
