Angry Brand new battery, bike still doesnt want to start..!

I had my headlight go out a few weeks ago, and did the jb wire switch...which cured my headlight problem. I don't know if they are related, but now my bike doesn't want to start...bought a new battery, (not the sealed one, read about that too late) but it will only start after I put the battery tender on it. It stalled after an hour long ride, so it must not be getting a charge. I don't understand how to check all the grounds, and wires, etc. I bought a multimeter but don't know how to use it. I did check the battery after a full charge, and when i revved the engine (to 5000 rpms) it didn't go past 13 volts. That's all i know...what could it be, an d how do i check for a problem? I need explicit instructions as I know nothing! The forums are great, however. I have been reading for the last week to figure out my problem but need an easy way to check things..! Its an 03, and I have owned it for 6 years without a problem til now. Thanks in advance!

Charging system woes suck, but sometimes you can get lucky and it's just a loose wire. Start there, make sure everything is tight!

It sounds like either your R/R or stator has failed, most likely the stator (especially after 6 years).

The first step to diagnosis is learning how to take readings with your multimeter. You need to learn how to measure AC current, DC current, as well as resistance.

Once you have the basics down, check out this flow chart. It should get you started.

If you mean you took the stator cover off and oil was inside, look where the oil cap is in relation to it.

A visual inspection of the stator won't do much, sadly. Just run through the multimeter tests and they'll be 100% conclusive.

The JB (headlight issue) and the charging issue might be related, the headlight relay is probably burnt out and corroded on the yellow wire if this happens, the r/r doesn't work right. I know I am going to get flamed for this, but I do know I had a problem with both my headlight and charging system. The PO sold me the bike because he replaced the R/R three times and the Stator twie in less than 6 months, the new charging parts would fix the problem for a short amount of time, but then the problem would come back. I noticed that when the bike wasn't charging, the headlight also didn't work, so I like you did the blue wire trick and fixed the headlight, but figured I should fix it right so bought a new JB. Presto my headlight worked once again, and when I tried digging deeper into my no charge issue found it to be gone. I don't know how long that fixed my problem, because shortly later I scrapped the JB all together and rewired the bike to my needs. But I do know I am still charging on the same R/R and Stator that the PO put in March of 2008

You seem to have the wrong link William.
That is Tuxedo Seven`s stator mod video.

Here is one link to some basics in using a multi-meter:
