I have a 1993 CBR600 f2. It runs great but I am draining batteries left and right. I went riding today and it started cutting out and died. Swapped batteries and it made it home. Barely.

I tested both batteries and they were bad so I bought a new sealed one. Pre-charged. Started up and ran perfect. I thought it was fixed. But it ended up dieing again.

I had this problem before and I changed my stator and the sensor that is under the cover. I thought it was fixed. I rode it for a few days then it sat for a couple weeks because it got cold. Now its messed up again.

How can I check to see if it is charging? If the stator or sensor is bad where can I get new ones? Could the rectifier be bad?

 

Just adjust the values for your bike (though it may be the same between the F2 and F3):
