Problem: '03 600RR Charging @ 17.6V
I have recently been having issues that (using a search) led me to believe that my "symptoms" (battery randomly lost its charge) were caused by the stator on the '03s getting to hot. The only fix provided was to replace the '03 stator with one from an 05-06. I think it was Moman who said that. I just found my meter this morning and decided to check the voltage on the battery, charge it, and then get some numbers from my bike.
The battery read 12.6v its about 2 months old
Ignition on - 11.9v
Starter turning- 8.5v
Running @ Idle- 17.6v
Running at 5k - 16.5v
Now sometimes I go on a short ride (5 mins) and I can stop and restart the bike. Sometimes on like 15 minute rides, if I turn it off it will crank over slow and I have to roll start it. The bike runs fine when its running, and the battery shows just above 12.v although I have not been able to meter the battery aftter I ride it and it wont start again.. SO Im pretty sure that Its charging to high, and/or I have a shorted cell on the battery. I have also heard that when batterys get hot, the plates inside can move and not make a good contact.. Any Ideas? Thanks for any help guys.
