Battery won't hold charge

I own a 1998 Honda CBR 1100. Battery was not charging so I replace the battery, stater and the rectafyer.  And now the stater is bad again, and it will not hold a charge. I don't understand what the problem is. Can someone help please
Thanks  

Could there be a fault with the wiring? A short, bad ground or something along those lines?

Good luck getting it sorted out.  

thanks for your help.do you happen to know what part of the wiring that it could be.  

This is where the service manual comes in. There should be a rundown of how to track electrical/charging system faults.

I would start simple- put a voltmeter on the battery and see what the voltage is with the bike running and also at 5,000 rpm. Should be high 13 to low 14 volts.

Do this when the bike is cold and just started. And then do this with the bike running after it's been ridden.

I've experienced rectifiers that are fine when cold but go haywire when warm.

If you are sure the battery and the rectifier are working properly, something else is not right.  

I had the same problem with a new ST-3 Ducati. It was the main
fuse right by the battery.  

thanks i will try thaat now. Just don't get it  

yeah i have an 02 yamaha r1 doing the same thing??
