ANYBODY KNOW OF ANYTHING IM NOT CHECKING ANY HELP WOULD BE APPREICATED!

I have been working on this bikefor about three or four days reading wire and scehmatics! I have come up empty handed for an answer to the problem. The guy that owns it said he has gonna thru two bactteries this is his third one and wanted someone to look at it! the battery test good 12.3 volts but want turn the bike over and start the starter just clicks. If you jump it off the the bike will run fine! if you turn it off with the master switch and then turn it back on it will start up but if you use the kill switch then it will just click! the stator is charging the battery at 14.2 while running!

THANKS

 

Sounds like a load capacity problem. A battery can show proper volts but be crap for current output.
