Just took bike out. it is very hot. Issue is that the voltage started out at about 13.5 then started to drop. After a few miles it was 12.7/.8 at 4K RPM. I hard wired the connector from the stator to the voltage regulator and also the #77 plug. both of those connectors had melted. When the stator to VR connector was going out the voltage kept dropping until it was down to about 11.8 consistently. Anyway any ideas or suggestions. I still think the engineer that designed to electrics on the 06 should find a new line of work. | ||

Not normal at all. Sounds like either the VR or stator just died, OR a real long shot, your connections are loose, or the battery just went kaput. All easily diagnosed with the shop manual. Bruce | ||

And it's not the engineer. The system is extremely well packaged and laid out. The issue is in the parts supply chain. The people who made the connectors and plugs and terminals simply did not make stuff up to snuff. As noted, run the stator tests per the manual, checking for output AC voltage and for grounded legs / shorts across phases. That will tell you if you have a stator problem (which can be caused by the bad connections), or a VR problem (also can be caused by the bad connections). I got lucky on my '06, and only put about an hours' riding into it with a bad 77. Once I got it fixed, all is well - and it stayed well all the way through our 2200 mile Homecoming trip last week  | ||

I went out this morning and started the bike. The volts went up to 13.8 -14.1 at 4K RPM. That is what it has been running since I hard wired the #77 and also #69(?) plugs. It was only in the mid 80's in the garage this am, versus about 98-100 when riding yesterday aftenoon. Seems like perhaps heat is causing some sort of problem. Any ideas. If I check the stator now (which I did in the spring when I hard wired the stator to the VR it was within spec. on all three wires) seems like I would get a good reading. Is the stator or VR very heat sensative and would cause a problem if it got too hot? | ||

----- vibrations ----------- cause a lot of problems that can usually be fixed fairly easily. It's a good way to learn about the machine for sure! Good luck! I'd say it's probably a loose wire, connection somewhere | ||

2500 RPM should be enough to see the voltage rise to 14 or so. If you have to rev it up to 4K, there might be an issue there. | ||

VR being a solid-state air cooled device is certainly prone to heat problems, much more than the stator which is just made of copper wire. Spray some freeze spray (from Radio Shack or some "air in a can", the kind with liquid in it, held upside down so the frosty stuff comes out) on the VR when it is working poorly and see if the voltage changes much. | ||

I am an amateur here but doesnt the output voltage drop if the battery has a full charge? | ||

Not that I could tell. It brings the battery up to voltage X and just keeps it there. I don't have my notes handy, but I think X is like 14.2 volts. It's a lot higher than I expected. | ||

I want to say the manual test RPM is 2k. 4k is too high a number to have to hit in order to beat 14v. Check your stator now. Check your VR now. Do it by the book, including "by the book" RPM. I suspect the answer will appear. | ||

The charging system has to recharge the battery and run everything electrical on the bike.That's why the VR holds the voltage around 14.something,to keep everything on an even keel.Even at idle the stator will put out over 20 VAC but that doesn't really tell you anything.If you do it by the book then you have a specific reference to judge performance by. | ||

Thanks. Will check out stator again. Seems like there were problems with the three pole 06 models. | ||

I was getting too much voltage and blowing my headlights out. I changed the VR but it started again so I tested the stator and it was bad so I wasted my money on the VR. Test the stator first. There are three test I believe. If any one test fails replace the stator. It's cheaper to learn from the mistakes of others!! |
