Electrical issues

I have an 04 919 that's been giving me a hard time as of recent. It's pretty hit and miss when it does happen, but here are the symptoms.
I'll be riding along with a full tank of gas and then my gas light will come on. Within a minute or two all my gauges will die, and then the bike will die. I'll turn it off and then back on and my battery will be almost completely drained. Or at least too drained to start the bike. It will start off of a bump start however.
I brought it into a local dealer and they checked the battery, and it was good. The also told me the stator was fine as well. I left it with them for a few days so they could see if they could replicate the problem, but they couldn't.
Anyone have any ideas? I was just going to keep driving it and bump start it when I have to. At least until the problem is more frequent, and then have the dealer check on it again.

Battery load tests are somewhat suspect. You don't say how old or what brand battery you have so I'll asume it's the original. Put a new yuasa battery in it and the problem will most likely go away. If not, you have removed the most likely variable. Best of luck.

Oh, by the way I just put a new Yuasa in my '04. It really helped the way my bike runs and I wasn't having problems yet.

Your assumption is correct, the battery is the original. I'll give it a shot and hopefully I won't have to take it back into the shop again. Thanks.

I had to run a new ground for my batt/Wire harness.There is a ground under the tank(right side as your sitting).I had to keep cleaning.Finally I ran a heavy wire from the batt to this grounding point,no more worries.

Welcome to WT, gecko. I'm betting Fastback is right and a new battery will cure your bike's ills!

i'm sending you $500 casino dollars for referring a new member. I'd say don't spend it all in one place but it's only good in one place!

Battery is a no go. I bought a new one and tried to run some errands on it. I got 5 starts out of it then it died while I was riding it. The battery was almost completely drained.
What's the easiest way to check that grounding wire tvetree mentioned?

have you verified that the alternator (or is it a generator? hmm) is charging the system? You may just be running solely off the battery.

1. Recheck the (+) and (-) leads on the battery. Make sure they are tight.
2. Test the charging voltage: Start the bike, put the high beam ON. Run the engine at 5,000 RPM's. The charging voltage measure at the battery should be 15.5 volts DC.

Here's a pic of the ground,I'd say clean it just because your having problems.
https://wristtwisters.com/forum/attac...2&d=1204997815

The neg for the battiery is hooked to the starter,real pain to get to(lack of spec tools).

I found mine by accdent.I was fixing to jump start it had the neg on my batt and bumped the frame with the other end and the fuel pump sounded.My batt still had good juice but a poor ground so I ran a new one.My batt now grounds to the point in the pict,not the starter.


Your's sounds more like a bigger/diff problem than mine but it's an easy check.
Jumper cable to neg post other end to frame. Passenger foot peg worked for me.(course need a gharged batt and hard to test going down the road)

I brought it into the shop and they were finally able to track down the problem. It was the regulator rectifier.
Any thoughts on replacing it? They said it'll cost $170 for a new one. I'm thinking it shouldn't be too terribly difficult to find a better deal and possibly just replace it myself.

@919VQ
I do believe so, I haven't had a chance to look at it though, they just told me over the phone. They also mentioned the 4-pin connector to it on the wiring harness was shot.
Thanks for the link.
