OK. I have traced the problem. It is the HID head light upgrade. I disconnected the battery feed to the headlights and my battery voltage jumped to 13.6v @ 3500rpm. So, I will either restore the original headlights or add a switch to the HID. I am leaning to the latter. The original headlights are not strong enough to safely ride at night above 25 mph. This should be a warning to all the others considering the HID headlights. Terrific responses from everyone. BIG THX!  |

One thing I left out. At the end I disconnected the negative terminal. The scoot continued to run normally. This should tell me that the stator is enough voltage to run the scoot. Correct?

Here's what I have found so far. Initial battery voltage is 12.13 (needs to be fully charged but adequate for the test). Scoot started with no problem. Battery @ 2000rpm is 12.18v Battery @ 5000rpm is 12.31v Installed new R/R. Tested the diode. Correct polarity shows a 0.4v drop which is what I would expect. Reverse polarity shows open, also what I would expect. Started the scoot and got the same voltage results as above. Disconnected the diode and shorted the connector. Lights came on (expected). Scoot started. Same voltage results as above again. Is there a way I can test the AC voltage from the stator before I tear into it to replace it? Have I missed anything?  |

Thanks all! I will post what I find out this weekend when I tear into it.  |

I looked for another thread and didn't find one. I hope I'm not duplicating an existing discussion. My battery is not charging. With the bike running, voltage at the battery is 12.3~4. Revved to 4K and there was no change. I expect to see 13+ volts if the stator is working correctly. Once started the bike will run with the negative terminal disconnected. This would indicate that the stator is doing something. I've had the battery load tested and it passes. After a short ride, the battery is dead and won't start the bike. The fact that it runs with the battery disconnected confuses me. I've ordered a voltage regulator and a stator. I hope I'm on the right track.
I have the 257cc Yamaha engine.
I have upgraded the headlights to HID. It ran well for a while after the upgrade, so I don't think anything is wrong with that.
Is there anything else that I should be looking for? |
