Tpoppa, you should read this thread entirely. It has your answer. In my humble opinion, those installing a replacement HD stator are engaging in a waiting game with HD to see if the thing fails again under warranty or out of warranty. Stators are failing in droves with and without the "harness hack". We need some intrepid soul to send theirs to one of the re-wirers for a robust redesign/rebuild. I intend to do so as soon as mine fails (which I wish it would just hurry up and do). | ||

My 2009 CR had the harness changed at 7 miles on the clock. Voltage drops into the 12's every ride. Always starts out in the low 14's but drops into the 13's quickly and after 15 minutes or so will drop into the 12's and for the most part stay there until shut down. Does not seem to matter too much if I keep it above or below 5,000rpm. Dealer looked at the stator around 250 miles, reported all is well. 620 mile service will be done in a few days, we'll look at it again. | ||

mine does the same thing as whistlers, start it up 14. something...13s in town, while idling it is in anywhere from mid to upper 12s....run fast jumps usually to mid 13s. had the harness update put somewhere on around 1000 miles...now have 2700 miles... | ||

Can anyone post pics of fried stators?? I for one would like to see one. | ||

I intend to do so as soon as mine fails (which I wish it would just hurry up and do). I have. Actually, I have been discussing replacement/rebuild options with an aftermarket stator source. I am just trying to separate the problems from what seems like a sense of panic. I am aware that stators are failing at a high rate (I don't have enough info to know the actual failure rate), both with and without the harness upgrade. I just don't believe that seeing the voltage dipping into the 12s (with the upgrade) necessarily means your stator is on the brink. Lower voltage should be expected with the harness upgrade. That said, the harness is a band-aid for a stator that is not well suited to the 1125. Even if HD will eventually release an updated stator, I seriously doubt it's high on their priority list. Let's hope I'm wrong. An aftermarket source will probably be the best route to go. I know a few folks are working with RM Stator to hopefully develop something... | ||

i would have to agree now that im thinking about it for the voltage to drop into the 12s during riding and idling is normal but what i dont agree is when my volts sometimes goes above 15 then my IC gets dim, signals dont work, speedo shows ---, tach needle at 0. something is just not right. | ||
| Tpoppa |
U_J Sounds like you have an issue beyond the stator. I've never seen voltage above 14.3...might want to get the voltage regulator checked out. | ||
| Ultimo_justin |
I did check it out  i even went as far as putting a new one in and it didnt change anything, i checked ECM, Battery, even plugged stator back in the old way as if the harness wasnt there and still did the same thing. I have HIDs and an LED underglow kit as my only accessories...surely these dont suck up juice to bring it dont to 12 volts while riding. what brings it up past 15 is only when im going really high RPMs 7k+ and have no lights on at all. either way im taking it in the 17th, them clowns can figure it out. | ||

May be a bad ground from the regulator Ultimo... | ||

well....just got the call from Harley this morning that my stator recall part(s) were in. before running my bike in i wanted to make sure that they could fit my bike in & get it out the same day. when i got there this afternoon i quickly found out that it was only the harness that they would be replacing & not the stator, as first quoted. it will be going in first thing tomorrow morning. i will keep you all posted as to what happens down the road. | ||
| Bigschwerm |
I just seen pics of a failed stator after the harness install... not looking good. Shall see as time goes by. | ||

My Electrical system died today, likely the stator. The volts just kept dropping and at 10 volts it dies. 2500 miles. HD admits the stator issue is heat related. Does a better built stator resist heat or is a redesign of the stator cooling system the true answer. Is this the 800 lb. Gorilla in the room that nobody wants to talk about? | ||
| Brumbear |
A better stator would absolutley work the 08's have no issues. Pdawg I feel bad for you as the stator replacement is necessary in most of these bikes especially if damge is already done and it seems likely if you had a problem | ||

The 08 stator appears to be more solidly built that the 09. The 08 has 18 spokes vs 12 on the 09. The 09 is slightly larger and generates more output. The 08 either generates less heat or manages it better. Personally, I would rather have the 08 stator retrofitted to my 09. | ||

I'm going to assume that a stator is a stator is a stator. (PLEASE no lectures on the differences between motors and generators and alternators and magnetos and dynamos...please) This whole issue may be a very simple issue. I agree with the above folks who think a rewind shop needs to examine several failed stators. The issue may not be related at all to the stator design. This could simply be a quality issue from a supplier. For example, "bad" insulation (varnish), improper bake temp. Insulation was not done in a vacuum tank with the result of uneven coverage of the windings. There are a whole host of things that could cause this problem. Harley needs to do some of that electrical engineering stuff and find the root cause of these failures. The stator design may be perfectly fine.

Just to add to the data, but nothing new to report: Had the Harness Recall done around 1K miles. A week later got caught in road construction traffic on a hot day. Temps went up over 220f and as I was pulling into my driveway, battery light then engine light came on. Shut the bike off and called the dealer immediately. He advised I trickle charge the battery and If problem persists, bring it back in (an hour away). I also double checked the Install of the Harness per info here, and all seemed well. Bike seemed fine for two more weeks. Then had a business meeting in Boston and was caught in traffic again (on another hot day). By now I was watching the volts and noticed them dropping rapidly. About 45 min from home battery and engine light come back on, and volts were dropping like a rock (11.2 ish) so i clutched it and revved it in stopped traffic and was able to get it up to 12.1v but no more. Nursed it home, called the dealer. He suggested for the heck of it to go to napa and buy a new solenoid and replace the one that came in the Harness upgrade kit. I noticed when i took the Harley one off it was oxidized on a couple of terminals already and melted around one of them. It also rattled when i shook it. Replaced it with the napa one and bam the voltage improved to 13.4 ish. I still loaded it on the trailer and took it up the next day for diagnostics. Something fried the original one. When they got it, they worked with Harley Tech support and decided it was a weak/failing stator. My service manager also decided to replace the regulator and battery as well, claiming that a failing stator can cause spikes and therefore a recipe for down the road failure. These guys rock, that's why I drive the distance I do to use them. Anyway, got the bike back yesterday, and haven't gotten to ride it much yet, but from what i can tell all is well again (for now). We're waiting to see if Harley wants us to return the failed stator, if not, they'll mail it to me, and i'll contribute it to the R&D rewind cause. Pete | ||

I also wanted to add, i've used my bike all throughout the RPM range, but admittedly, i don't like how it feels or sounds around 7500 rpms (like it needs to shift) so I tend to keep it below that. Now for conversation, my buddy bought his 09 CR at the same time I bought my 09 R. We got a package deal, and he has similar miles and the harness recall done a week after me at about the same mileage. He tends to drive it a bit softer and in town, but his CR is charging fine and doesn't have any symptoms of failure yet. As we've discussed this, the only thing he hasn't experienced yet is prolonged time trapped in traffic. So go figure. | ||

When my stator failed I was on a road run with a bunch of Harleys and a few metrics. Open country no city traffic to speak of at all. Up until then the bike was fine in short hops of city driving. This event started at 10am and concluded after 7pm. At least 9 hours of riding and stops for food and gas. That's why I think heat is the issue. I would like to believe that HD has a better version going back on. Can anybody tell me if the original 09 stator has a new superceding part number? | ||
| Brumbear |
no way, thats why if mine goes it is going to a rewind guy I am not letting H-D touch my machine if I don't have to. It's not the dealer so much as it is the situation H-D doessn't have to care at this point they just have to honor the warrenty so they will replace it with what they have more than likely and hope for the best ergo the cheap fix on the harness | ||
| Dannybuell |
HD will see me again and again. I have no trouble putting 10K a year on a bike. At 2500 miles for the first failure they will likely do this three more times before my warranty goes out. 10Kmi a year will be very easy, I am crazy about this bike. | ||
| Tpoppa |
Can anybody tell me if the original 09 stator has a new superceding part number? Nope. But we can hope. | ||

I've heard enough examples of post harness upgrade stator failures (you can add mine to the list) to be fairly certain that the harness relay is not a viable solution. It's going to get expensive for HD to keep replacing stators under warranty. I just hope it 'bubbles up' enough to convince HD that it's cheaper to design a new stator that lasts. I encourage anyone who's had a failure after the harness upgrade to contact HD/Buell customer service at 414.343.8400. Follow the proper channels, log a case, and request information on HD's solution to this problem. Enough cases are bound to get noticed in a squeaky-wheel-gets-the-grease kind of way. | ||

well...when it rains it pours. just last week i had my charging harness installed by Harley. just over 4000kms. then i just finished these upgrades: HMF ECM, HMF pipe, de-noid, breather bypass & K&N. took it for a good ride today & was gonna show it off to the guys at my Harley shop. in traffic, just across from the shop my battery lite came on! i quickly switched the guage to find that the battery was 11.8. i revved it & the lite went off as the volts went up to 12.4 when i hit the shop the lite was back on & revving it didn't help. when the service advisor came out it was 11.9 with the lite on, as he revved it, it dropped to 11.8, then 11.7, then he shut if off. he said they will get a stator on order ASAP. as he was admiring my CANDY BLUE HMF pipe he said: "whats all that oil splashed on your pipe?" GUESS WHAT??? CLUTCH WEEP!!!!!!!! serious clutch weep!!! when it rains it pours. just as the weather improves, my 1125R fails. they said to limp it home & they will get all the necessary parts in ASAP. i could just cry.....seriously  | ||

I figured every 09 has had stator failure so why not check it? Following the electrical manual: Check each terminal of stator connector to ground, if continuity things are bad. OK Check resistance between any 2 terminals, if > .1-.3 ohms things are bad. OK Check AC voltage between any 2 terminals, @3k rpm, 45-55V AC. Terminals 1 and 2 make 3 V AC! All other combinations meet spec. | ||

alrighty that does it im confused to all hell. i was driving it like normally to work today and the IC says SYSTEM VOLTAGE (only going 25 mph in 1st gear) IC goes dark, speedo says ---, blinkers dont work but bike still runs, when it comes back to i switch over to the volts and its 16.1, pull into the parking lot of my work and with just the fans running the volts drop down to 12.5 now i wanna cry. good thing it gets taken in the 17th. | ||

OK the 08's have a slightly smaller stator. Is the rotor (or what ever they call it, bolted on the end of the crankshaft) the same part number or is it sized differently as well? I am wondering if the 08 parts can be put on the 09's? It seems to me that less charging would be far better then no charging..... | ||

I've been told the 08 has a different voltage regulator also, but I have yet to verify. To retrofit you would need the 08 rotor, possibly the regulator too. | ||

Pdawg1970 - That happened to me when I got my 96 S1 so many years ago, it went down for a part of the first summer. This time the old girl (95Kmi) backed me up when the CR stator died Saturday. That took a lot of the sting out of the failure. Is someone taking the old stator to a rewinding service for evaluation? As Kirb mentioned early on in this thread the weakness could be any part of the stator; the iron core, windings, or varnish. It would be nice to know what aspects of the stator are less than superior quality. Is someone still looking for a core? I will check in tomorrow am to see whether I should ask dealer for old stator.

Anyone with a failed stator actually test it? What diagnostic test do they generally fail? Continuity to ground Resistance between coils AC voltage output ac |
