What's wrong with my charging system?

I have a 1983 Honda CB550SC. A month or two ago I replaced the regulator/rectifier, and yesterday I replaced the stator. The output off the stator is ~12v AC at idle, and goes up to 15 at higher RPMs.

My battery is a lithium one by Deltran. I charged it over night on Monday (13.5v), and yesterday after replacing the alternator, went for a short ride to an appointment and back home, then was going to a friends house I got a mile away from home and it just shut down. I've learned to ride with a multimeter and it was down to 9.x v. I had someone jump me and left the thing at a friends place. So with my alternator obviously putting out a charge, what is wrong here? I'm at a total loss.

Another bit of info, not sure if it's relevant or not, is that my signals speed up with higher RPMs and slow down at idle.

Is it a bad idea for me to refinance my original Honda auto loan?

My credit has improved over the last 6 months and I would like to refinance in another 6 months or so once I feel more comfortable with my score. BUT is this a bad idea? Will Honda scold me for this when I go to the Service dept for maintenance? Or will other future lenders see me as some sort of unreliable consumer moving forward? I worry about this. Any advice would be great and much appreciated!

Honda foreman 400 won't start?

Added (1). I have a 2000 model Honda Foreman 400 (trx400fw) that has blown the main fuse and is going straight to ground from the main fuse (realized that by doing a continuity test) additionally, the fan comes on and stays on when the switch is turned to the "on" position and the starter is not getting power when the "start" button is pressed while in neutral and holding the left brake lever. (the starter itself works) any suggestions on what to check next?

How much should it cost to fix a tiny crack in the back of someone's car?

I was getting off the high and accidentally hit my friends car in front of me. I basically just rolled into her so i was not going very fast. When we looked at the damage all we could find was a tiny crack (about 1-2 inches) on the back "bumper" I think you would call it (it's a Honda). And the paint might be a little loose. Personally don't think that it's worth fixing but she does. Is it worth fixing? And how much do you think it ll cost?
