battery carging problem

Ok so heres tha problem i bought a new battery for my R1 it ran fine for a few days but then tha battery went dead. I don't know if its a charging sys or wat no clue.

Was the battery charged before installing it? Also check the connections, sand them with some sand paper.

Look up rectifier / regulator. I am in the process of dealing with a bad rectifier regulator right now on an 00 .... http://www.r1-forum.com/forums/showthread.php?t=194553&goto=newpost

or else it could be the stator. I replaced the voltage regulator, held it's charge over the winter, then went to drive it a few weeks ago, lost it's charge. brought it into the shop, said the stator went bad, and it only has 6500 miles on it. Stator and voltage regulator were big issues for these bikes.

Well if you already replaced the R/R and the Battery is new than you are left with the stator. I am told that if you run a continuity test to each of the white wire in the recitifier, you should not have continuity. If you do you have a bad phase on the stator.

Check the voltage across the battery terminals with the engine off and with it running. With the key off, a fully charged AGM battery like in the R1 should have >12.8 volts DC across the battery terminals. With the engine running and charging properly, the voltage across the battery terminals should be ~13.5 volts DC or higher.
