I have an 03 600RR, new batttery. For the past month or so it would have a hard time starting when the bike was warmed up, but it started fine when it was cold. I checked the battery and it said i had 12.7 volts. I checked the leakage on the battery and it was about 1.1 amps. I thought it was the regulator/rectifier, i replaced that. Battery was acting as if it was dead, so i charged the battery, started the bike and took it for a ride. Turned it off and now it acts as if the battery is dead but still says 12.7 volts. Everytime i try to start it the trip odometer and the clock reset like i disconnected the battery, but i didn't. It just has what seems to be, NO JUICE!! HELP!!!!!

 

Fuses? Will it start? Load test the battery?

 

fuses are fine, at least the ones located next to the regulator/rectifier. It will start ONLY if i have the bike attached to a charger and i let it crank for a while, other wise after like 3 attempts at turning over the battery acts as if it is dead.

One guy suggested that it might be the battery, so this weekend im going to borrow my friends battery that i know is good and see what happens then.

i was also thinking it may be the starter, but what part of the starter. i do not know what to check or how to check the status of the starter.

 

Is it still drawing 1.1 amps after you replaced the regulator/rectifier? That's a huge amount of leakage. I'd say its a short somewhere.

 

I used my friends battery and the bike started up AWESOME!!! does that mean thats the culprit? or does that mean something is causing my battery to die slowly over time? the battery store is currently testing my battery over night and i will find out the deal tomorrow!

 

Its hard to say what fried your battery. Some times, just because the battery has the voltage, it doesnt have the amps to crank the bike. Batteries get weak, they break down inside. they can shortout internally causing this. rectifiers go out and either overcharge the battery or do not convert the ac to dc power and it ruins the battery. but then again, sometimes batteries just fail.

The main thing you need to do once you get a new battery is test your entire system. Check your voltage at the battery with the bike running around 3,000 rpms, then again at 5000. if you have less voltage at 5000, your stator is probably on the way out. If you have the normal voltage at both, your in good shape and I wouldnt worry about anything. However, if you show more than 15 volts, your rectifier is bad and will need to be changed imediately.
