My son's 07' has had this problem on and off for over a year but seems to go away on its own until now. I just got done putting it back together after a rocker box leak fix. I put the multimeter on the batter with the engine going and it is only showing about 12.8 volts or so and it should be showing 13.6 or better so it is not getting a charge. Give me some help for what I should be looking for. I already got rid of the 77 connector so that is not it for sure. What else??? | ||

UN plug the stator wires from the regular/rectifier and ohm poles (from the stator) 1 to 2, 2 to 3, and 3 to 1.... You should get roughly the same reading on all three (.1-.3). Then ohm all poles to ground, you should get no reading to ground on any of them if the stator is good. If not replace the stator. If all is well then it is either the voltage regulator/rectifier or a bad ground. (Message edited by gp81 on May 29, 2014) | ||

Stator output should be around 45v AC (yes...AC) at 2k rpm, on each of the three legs. If you have a manual, it is under "stator test". | ||

Thanks for the info guys, I'll be testing my 09 , since it's just stopped charging. | ||
| Goodburbon |
Only 2 wires from the stator on my 09 XT. 20-22VAC Output from VR is 15vDC. Battery voltage when running is 11.5. Where is that 15 volts going? | ||

Electro, hopefully its something easy like a dirty ground or something, but: If you find it's your '07's regulator I recommend this (some consider it an upgrade for less money, myself included, mine has been going strong for quite awhile now): http://www.roadstercycle.com/ If its the stator, (I have replaced my stator twice now), I got mine here: http://americansportbike.com/newdir/Item/17167 (as you could guess, they also have the stock regulator) Additionally, I installed this little gizmo to keep an eye on things and I really like it: http://www.amazon.com/Signal-Dynamics-Heads-Voltag e-Monitor/dp/B00AC5J84M | ||

Thanks all for the helpful posts. I'm not sure what is wrong with my son's 07. No charging this morning until after I cleaned all the electrical plugins down by the front drive pulley. Then I took if for the first ride after the engine rotation and it was running like crap. All of a sudden it started running good and I hooked up the multi-meter and it was charging like it should. I will do a TPS reset and hope it runs even better since it is acting odd with the idle. But the intermittent charging is OK for the moment. I think for sure that I will buy a Zero bike within the next year or so. These internal combustion engines blow and have way to many parts in comparison. I'll keep my ULY or 97 glide for the long hauls. | ||

The idle issue was another brain fart. Found a piece of paper towel stuck in the butterfly valve. Not even sure how much paper towel went through the engine or if any did at all but wouldn't bet against that having happened. Idles good now but charging system not charging battery. | ||
| Electraglider_1997 |
Not charging again. On the Stator 46 connector plug, how do you tell the 1 socket from the 2 and 3 socket? Can these 46 connectors quit making contact within the connector? This charging problem is intermittent so is that possible with a bad stator. Could the regulator cause this intermittent charging. Where exactly does the black ground wire from the 77 connector ground at? I'd like to make sure that isn't the problem. Thanks to all who have chimed in here. | ||
| Gp81 |
Doesn't really matter which pole is 1 2 or 3.... Just use one as a reference and call it 1.... Basically you just want to test all of them against each other and make sure the ohms are approx. The same, should be between .1 and .3 | ||

Thanks for all the advice because it has cleared up the confusion. I bought a decent multimeter today and did a stator test and thankfully the stator checks out ok on all the tests. Not so for the regulator. The ground wire coming out of the regulator tests out that is grounded and the red wire is not shorted to ground for sure. But when the engine is running the voltage across those two regulator output wires only reads a steady 12.7 volts and that guarantees the battery slowly runs down. Can the regulator be taken apart or is it "just good" or "just bad" and that is that? Should I go with the Mosfet or just stick with the OEM regulator? Thoughts on this would be appreciated. Will the Mosfet regulator bolt right up the same as the Buell OEM unit? | ||

Goodburbon - the early bikes had a three phase system, yours has a single phase. Your stator outputs VAC, not VDC. The volts "going away" is in the conversion to DC. Read my first post - 45VAC is spec at 2000 rpm. The regulator converts that to 13VDC for the bike system. EG - see here: http://www.badweatherbikers.com/buell/messages/142 838/712127.html I've seen ROCK-SOLID voltages since the install - zero fluctuation based on RPM or load. I am tickled pink and highly recommend it. | ||
| Djohnk |
EG: As you can see from Ratbuells link it won't bolt right on. I noticed roadstercycle.com now has an adapter plate ... don't know if it works for the uly though. | ||
| Electraglider_1997 |
Ratbuell, Awesome link you provided. A bit of work but straight forward and it personalizes the bike when all is said and done. Djohnk, Thanks for the advice and link to the Mosfet. Gp81, Thanks for the answers regarding the 46 socket because I have a tendency to get stuck worrying about the small details. I like to know things 100%. Every time something different goes wrong with these bikes it allows for a new learning experience. Knowing how to fix things certainly is helpful when you take these bikes on long trips, and I'm referring to any bike not just ULYs. At the cost of things it is always nice to save a buck by being able to diagnose and then do your own work. And it is always easier when you can ask those that have experience. Thanks to everyone.

Interesting, I just noticed that roadstercycle.com also added a Buell 3-phase stator on there for $99. I didn't look into if it fits my '07, but anyway that's a pretty good price. | ||
| Ratbuell |
06/07 (actually any XB up to and including 07) will be three phase...so it should fit. Jack's great about customer service...drop him a note | ||
| Electraglider_1997 |
Ratbuell/Djohnk, Does it matter which order the Buell stator wires get hooked to the 3 wires going into the Mosfet Regulator? | ||
| Djohnk |
Nope doesn't matter. He's got some great installation videos on there if you go that route. Make sure you check them out before you order, it will help you decide which kit to get. | ||
| Ratbuell |
No, because stator output is AC. | ||
| Electraglider_1997 |
Thanks. Here's another couple questions: 1) Did you both order the FH020AA? 2) Why is considered to be better than the stock regulator? | ||
| Djohnk |
EG: 1) Yes I used the FH020AA and wired it directly to the battery with a circuit breaker. 2) Not sure why its considered an upgrade (some on here might argue not), but it has worked great for me so far, can't say that about the stock one. | ||
| Electraglider_1997 |
Djohnk, Thanks for the answer. I'm ordering one today. I watched some of the roadcycle videos and tested the suspect regulator diodes just like in the video and found that 3 diodes were shot. The videos help dispel some of the mystery of these regulator/rectifiers. | ||
| Ratbuell |
Like I posted in the thread I linked...I put that one in because it's more common to more OEM's, so replacements should be easier down the road should a failure occur. I have already retrofitted the bike to accept this unit, so now if it fails...simple plug and play. Although as rock-solid as my voltage gauge has been since the install...I don't know if it's ever going to fail. It doesn't even hiccup!! | ||

My Shindengen conversion was a little more time consuming but I'm still very satisfied with the results: http://www.badweatherbikers.com/buell/messages/142 838/667134.html?1326751428 | ||

I installed the Mosfet R/R from Roadcycle. Works well. It came with some severly undersized connectors so I just soldered the wires together and covered with shrink tube. This is on my son's 2007 ULY. If my regulator/rectifier ever gets fried I will buy the Mosfet but will do all the connecting myself instead of buying the Super Mosfet kit. Thankfully the stator checked out good. Roadcycle has good videos , especially the one that shows how to check the R/R function with a multimeter. Mine had 3 fried diodes. The bracketing of the Mosfet to the ULY took some thinking but after sleeping on the problem it came to me and the finished product turned out real nice. Remember to use your stock R/R as a template for hole position. | ||

FH020AA, It also worked well on my 08. Can be used on 2 or 3 wire stators. | ||

he bracketing of the Mosfet to the ULY took some thinking but after sleeping on the problem it came to me and the finished product turned out real nice. Remember to use your stock R/R as a template for hole position. How about a pic or 2 of the install? | ||
| Electraglider_1997 |
Hugh, I'll take some Mosfet install pics tomorrow and of the exhaust actuator fix. It's been awhile since I've uploaded photos to Badweb and this is a new computer so I have to figure that out. Tomorrow. | ||

"The Gimp" is a free and powerful image manipulation program. A non trivial learning curve, but that's less painful than having to deal with those bastards at Adobe, and it stays pretty static so what you learn now will probably be useful 10 years from now. | ||

I mounted mine on the bracket for the OEM one. Had to drill and tap for 1/4-20. Figure your mounting prior to wiring for it.  | ||
| Ratbuell |
Similar to mine,but I always (out of longstanding habit) mount my connectors pointing down:     | ||
| Electraglider_1997 |
Here's how I did it. Bought a lumber truss piece. Traced the old regulator outline and 3 hole pattern from a piece I hack sawed off the old regulator.  Hack sawed out the pattern and drilled the 3 bracket mounting holes. The 3 small screws are 10x24 screws. The longer bolts are 1/4 x 20 bolts with extra nuts for standing off the Mosfet regulator.  Side view showing the 10 x 24 bracket mounting screws with 1/4 x 20 nuts and washers for spacers.     | ||

"mount my connectors pointing down". Yes this is good working practice. EG and Ourdee. If not yet done fit a cable tie to the top of your clutch adjustment boot. Saves water ingress to the tranny case. A "number one" Uly mod. |
