#1: Charging Question!(SOLVED)

Alright, I got an electrical
question for you all. Last week, after work, went to start the bike and
the bike cranked slow. So got the jump box on it and it started. Rode
home, lights are not as bright as they are supposed to be. So I get home
thinking the battery just crapped out on me and I get a new one.
Everything was great for like 4 days. Then same thing, weak battery. Got
the jump box again and bike started. Got the DVOM and checked R/R output.
Less than battery voltage. 3000RPM took me .2V higher. So I rode the bike
home thinking I was gonna be stranded. While going home, some moron in the
fast lane was tearing it up so I punched it around him. Took the bike to
6K. Tach started freaking out. Fluctuation from 2 to 10K. All the while
the bike behaving more or less normally. No power surges, no power
decrease. Get home, check the white stator wires for power and resistance.
I got about 20-21VAC from the stator. Resistance is between .6-1.1Ohm. I
hook up to VDC and find that the voltage is now up again to 13.8V. There
are 4 wires beside the 3 white wires going in. There is a red wire which
is the main converted power out which goes to the battery. There is my
ground wire. There is a wire that takes a detour to the diode pack and
then there is an ignition switch wire.
Any clues to what may or
may not be going out on the bike as to the charging system? I thought that
maybe it was the regulator. But now I am leaning maybe to a bad ground or
possibly a bad diode. The wonderful schematics do not tell me which part
of the diodes in the diode pack to test.
I tried my best to
include all the testing I have done. Without any specs on the diode pack,
I would like to know if its good or bad instead of shotgunning away
without any reason. I am fairly adept to testing electrical if I know what
I am supposed to be looking for.
Thanks everyone for reading and
offering any ideas and/or clues.
*EDIT* as a side note, this all
seemed to have kicked off when my headlight relay bit the dust. I had "a"
relay, not the "right" relay. Regardless it worked except whenever the key
was on the headlight was on. When the battery went dead the second time, I
disconnected the headlight bulb from within the headlight bucket.
