charging problem

ok, i've been pouring over threads in here

went to start bike this morning 'clickclickclickclick'
well poop
jump it off car, starts up just fine, disconnect jumpers and it starts running funny and dies, jump it again and check voltage 14v while hooked up to car.
disconnect car and it drops down to 11v and starts running poorly.

get battery charged up starts just fine but doesn't run so hot

didn't get that burnt electrical smell from oil hole like greywolf recommends to check for.

find service manual, and start checking out leads, the manual is slightly different from my 07dl1000, the connector i believe to be from stator is 3 black wires (not yellow like in manual) and the r/r doesn't' have a big connector in the side, it has all wires, one going to stator connector(black with 3 all black wires) and one to a different plug (white with all black, black white stripe, black red stripe)

so what i find is there is continuity between all three leads, and its open to ground (so stator isn't bad then?) checked it while running and all three leads are producing well over 75vac @5000rpm (one was around 100 another 90 something and third was similar as well)

so i'm guessing now that my r/r is bad?
or am i missing something else?
can't quite follow service manual at this point because it diverges from what i have on the bike

so i beseech you, brain trust, where do i go next?

Clean and tighten the battery cables. The battery might be bad too.

Sounds like the battery is the first thing I would check. Charge it overnight and see what the voltage on it about an hour after you disconnect the charger. I am suspicious of a bad cell from the description. On the other hand, the A/C voltages sound a bit high also....

cables are tight and clean near as i can tell from when i reinstalled the battery a month or so ago (it was on bat tender jr all winter)

would that cause the undervoltage at the battery terminals though if charging system was working?

The battery can still go bad on a tender. They don't last forever even with the best care in the world.
If you can fully charge it and after an hour off the charger the voltage is still good it's worth looking further. If not you need to sort out the dud battery first.

forgot to mention something earlier, when checking the standalone voltage (no jumper cables) while running, if i reved it up it would drop even more to less than 10v, back to idle it would come back to 11ish

If I went out now and put a meter on my battery I wouldn't expect any better than that, but that doesn't mean yours isn't collapsing under load.

What happens if you substitute a known good battery? You could check this by disconnecting the bike battery and using your car battery (without the car running of course) and monitoring the voltage.
