Just got the news from my dealer. They are replacing both the stator and voltage regulator. Anyone have any idea what causes these to crap out? Is there a contributing factor to short life? I have used ONLY Formula+, so it isn't the oil eating it. Is there an effective life span whereby I should plan to replace it after XX,XXX miles? | ||

I like to look at the stator and do a post mortem on it. They short out or self destruct from heat ... So please ask for the old parts and check out the stator!! The voltage regulator/rectifier goes out on many bikes so easy to understand. Thanks for the report and look forward to stator report. Chas | ||

A few things can make them go bad. The insulation can breakdown and short the windings out to the core. On a three phase alternator one phase could open (break in the winding) shifting all the load to the other two phases which then overheat, breakdown the insulation and short to the core. (The 06 & 07 Ulys have a 3 phase alternator) Heat and/or vibration are the enemies. Since this seems to be a fairly common problem I would say that the stator is engineered a bit too close to the margins for the conditions inside the Thunderstorm or whoever is manufacturing them is not controlling quality properly. You might want to go to the aftermarket if warrantee is not covering it. Rick's http://www.ricksmotorsportelectrics.com/index.php? ch=stators or ElectroSport https://www.electrosport.com/electrosport_daker_re wind.html are two possibilities. I believe Rick's will rewind your core if they don't list a replacement. (Message edited by rwven on October 23, 2007) | ||

Its a shunt regulator, so the "less" power your battery can absorb, the more power the stator and voltage regulator have to "eat", which heats them up. Your best path to protecting your stator may be replacing your battery. And ironically, heat coming out "other places" like grips, is heat that is not coming out your stator / voltage regulators. Heated grips save batteries!  20k on my 05 9sx... not stator problems... yet. My original battery is now sitting at a fairly low voltage when the bike is turned off... it should probably be replaced this spring. | ||

I hope they get you your Uly back quickly! | ||

My dealer is awesome. As of today, they have stated that they will have it back in time to ride this weekend. I dropped it off Thursday morning last week. A week turnaround time to diagnose, order parts for, and install the parts is pretty good in my book. | ||

Ft_bstrd, your stator failed because you don't strain it enough. 17K trouble free miles of big ass fog lights, heated everything, electric cooler, GPS and whatever else i can find to plug in that day. | ||

My Uly is going to the same shop tomorrow morning. Same problem...  | ||

It's gotta be those burrito platters. Chad have you been doing lunch with the Ft one? | ||

I farted on his bike once. | ||
| Florida_lime |
Just once ?!?  | ||

The best electronics for my Harleys was made by Compufire. After three regulators from Harley I bought a Compufire and never had another problem. They have three phase alternators too. I had a coil fail after seven years and 50,000 plus miles and they got me a new one for half price. Excellent service. Don't know if they will fit a Buell but they are worth a phone call. | ||

Fatty, did you ever confirm that the sportster regulator works on a Uly? | ||

And ironically, heat coming out "other places" like grips, is heat that is not coming out your stator / voltage regulators. Heated grips save batteries! : ) I wish I had known this last week. I made of point of not running my lights with my aux lights so I wouldn't put stress on the charging system. PS: And people complain about the engine being archaic.

Quick question, as my 2007 died on me after 50 miles , but before rolling to a stop , hit the start button , fired back up and carried on ... happened again in 15 miles.. hit the kill switch off then on and fired up again.. After 30 minute break.. needed a refreshment as I was a ways from home...Fired right up and rode home with no problem.. Felt like it was electrical as it just died riding down the road .. any help? Greatly appreciated ... Thanks.. | ||
| Ft_bstrd |
Ah, 1stxb, call your dealer and tell them to order you a Bank Angle Sensor that you'll be in when it arrives. | ||
| 1stxb |
Thanks, ... I had heard maybe that would be it.. but this is the fist glitch with this bike since have owned it... And it was fine on the way home ..so wasn't sure.. Thanks again.. | ||
| Ft_bstrd |
"Fist glitch" Freudian slip?  I've had two crap out. You have an 07 Uly, right? You're the first I've heard with a BAS failure after 06. | ||
| Florida_lime |
1stxb, Just order the BAS like Ft_bstrd said. Worked for me, and I didn't even have to install it.  After more than 12 times of the bike dying like you describe, over the course of several thousand miles, I ordered a new BAS so I wouldn't get stuck somewhere. I have had over 6,000 miles since, with no BAS type failure. The new BAS is in the saddlebag if I ever need it, wrapped in bubblewrap to protect it.  | ||
| 1stxb |
Thanks FL.. I will do that.. I think it is a simple swap if needed .. correct? | ||
| Ft_bstrd |
Plug and play. | ||
| Florida_lime |
You're the first I've heard with a BAS failure after 06. Mine is an '07 also. | ||
| Ft_bstrd |
Where are the BAS located on the 07's? | ||
| Florida_lime |
I think the very early '07s were in the same place as the '06s, but most were in the tail location as per the recall. That's where mine always has been. | ||
| 1stxb |
Spell check doesn't catch Freudian slips? Oops.... '07 Uly and will be ordering one today.. Thanks.. | ||
| Ft_bstrd |
It's back and running like scalded monkeys! | ||

I'm not....waiting on a stator to replace my fried unit. |
