Can u test the stator and the vr/rect? Stator will give u ac voltage and the vr/rect will give out the dc volts, which shud read in 14-15 range dependant on rpm.

For the battery, marko is kinda right on just tt fact. However, pull the battery from the bike or at least disconnect it. Charge it to full. Full shud read 12.8 volts, then leave it sit. Re test and see if the voltage dropped significantly. If so. Dead battery for sure. Still not a bad idea to test the bikes charging system though.
