03 CBR1100xx

[kev7xx]

I have a 2003 CBR1100xx which I just purchased about a month ago. When I purchased the bike, the battery was bad. I replaced the battery and am having a problem with the bike not changing the battery. The bike will work for a couple of days and then I will try to start it and the battery will be dead. I purchased an OEM battery from the Honda dealer. When the bike is running, it changes arround 12.5-12.9 volts when the battery is fully changed. The other night, I went throught the service manual and went through the troubleshooting flow chart, and did the resistance test on the stator and it is within specs about .3 OHMS. and I checked the connectors on the rectifier/regulator and they check out fine. Durring my test I (of course) had to disconnect the RR, when I connected the RR backup I again checked the charging voltage and it was from 13 volts to 14.4 volts as I reved the engine. I rode the bike for a day or so and decided to check the battery voltage, noticed it was about 12.4 volts, checked the charging voltage and it was back to 12.6 volts, so I am not sure if it is the stator or the RR that is bad. Any advice will be appreciated. Thanks

Check down a few threads for "

"Battery/rectifier question"----------there will be link in there for an excellant trouble shooting guide. Follow it and you will most likely be able to identify your problem.

If the battery was dead and you charged it but didnt fully charge it, you can actually fry your regulator rectifier. Just like in a car the alternator is a generator with a voltage regulator and the part that fails is the voltage regulator. Anyways if you check ebay you can find aftermarket regulator rectifiers for a decent price but more than likely that is your problem. I have only seen a few bikes that have issues with the stator and its generally a result of a wreck and the engine case was damaged and it damaged the stator below (most common on dirt bikes)
