I HAVE CODE ON MY BIKE ,D10SEE CAL 04

d08SEE indicates a high voltage condition or possibly a bad ground or regulator on it's way out
Check your grounds as a starter then reset the codes. Usually you'll find that your stator is getting ready to take a dump. 2000 and early HD's were famous for frying stators.

You will need a OBD2 code reader, that will give you a "trouble code" then that will tell you what direction to look in, for the problem.
