me know if you fix it and how.I just bought a new battery.
Most likely a fault in the alternator diode pack, you will have to perform a battery draw test to confirm. Disconnect a battery cable, either one makes no difference, put a test light between the cable and the battery post, if the light comes on then you have a battery draw, electrically disconnect the alternator, if the light goes out then it is confirmed the diodes have a problem, if the light is still on then you need to start removing fuses until the light goes out, make sure you make a note as to what fuse went where, when you find that circuit then you need to trace it out to find the draw.
