First check the rectifier. It could be bad..(batteries don't much like receiving alternating current) then try cleaning your ground connections both at the battery and the frame.
And make them tight and clean. If this doesn't help then look for a short (+wire melted and partially touching metal) failing that ...look at replacing the battery (bad cell)

a1,2,3 are the yellow wires from the stator. B, battery, is the white wire. M, monitor, is the brown wire (switched power). G, ground, is the black wire.

A 1,2, and 3 can be plugged in in no particular order as it is 3 phase AC. The R/R smooths this to DC and regulates it for the bike to run and charge the battery.
