I always had battery light when i started up. Since change no light. All seems good. | ||

A new flash IS required...the bike must have 142/152 depending on R/CR. Supposedly Erik Buell Racing ECMs ALL have the stator control...but I have experienced that some do not. ac | ||

2000 miles after the new stator it has worrisome behavior; it threw a low voltage code two weeks ago and wouldn't turn over until I let it cool for a moment. One hour into a hot urban Stop and Go ride we stop and the battery light goes on after the kill switch. As we depart to return through this urban gauntlet the battery light is on before starting. One week later I checked the battery terminals, negative was fine but I couldn't get the socket around positive. I bent a connector back a bit, socketed the positive and found it darn near a flat short of tight! Volts seem to hold a bit longer but it still drops. I left work today at 3:00pm, downtown temperature in the mid 80's (F), within 2 blocks I could feel the tank, hear the fans and see the voltage dropping. This bike needs urban manners in the worst way. Every time I watch the voltage drop below 12.7 there is that moment of doubt. | ||

Danny, That sounds like harness upgrade 'behaving as it's supposed to.' Unfortunately, 'behaving as it's supposed to' is a serious compromise over correctly functioning stator. Personally, I have watched mine idle down to the 10s where it stalled...twice. The harness upgrade was the cheapest 'fix' that HD could come up with. After your warranty runs out, HD will be happy to sell you a $150 stator for $679  | ||

After having the harness upgrade and new flash of the ECM, my stator went out. Had stator replaced under warranty and now I notice clutch release RPM increase that went away after last ECM flash. Maybe harness and ECM flash was causing stator failure.... | ||

How long did you let it idle? I've let mine idle for 5 minutes before checking the oil and it's never gone lower than 12.5v. | ||

I was told point blank that no reflash was done when I had my harness up/downgrade. I asked repeatedly, and was told it wasn't necessary. I have very little faith in my local dealership, as the service managers seem very..."superficially involved". Without exception, everyone I know who had experience with them (admittedly, only three guys) had the same opinion about their pathetic sevice managers... So is it it a requirement to reflash with the new harness? | ||

The dealership said the flash was part of the harness upgrade. Ran great for 3 days, 200 miles. No RPM increase, lower running CT. Then the CE and BAT light came on. Replaced stator and now clutch RPM increase is back but still running at lower CT. Have not heard back on why the RPM increase came back. Will probably put an Erik Buell Racing ecm on it. | ||

How long did you let it idle? Both times I pulled into my driveway with volts around 12.1-12.2 (already too low for comfort). I held the brake and let it idle. Trying to simulate being stuck in traffic holding the brake (light on). I would say it took about 4 minutes at idle for volts to drop into the 10s, throw a code, and finally stall. I wonder if the idle problem is a bigger issue on the R than the CR. R has two headlights 2*35w vs the single 55w headlight on the CR. Were only talking about 15 watts, is that enough to make a difference? | ||

It states specifically in the tech instructions that the flash should be verified. If it is not current, the current flash should be installed. Without the current flash your harness will not do anything. In fact, I need to look at the diagram again, but you might not EVER be using all 3 stator legs. I forget if the ECM grounding the relay connects or disconnects the 3rd leg. ac | ||

nevermind...I just talked to the dealership where I bought my bike (8o miles away) and they told me a reflash was part of the package. Strike three on the service managers at the local shop. I only hope the tech who did the work reflashed the bike and the service manager was unaware. THAT seems very possible. | ||
| Buellrider66 |
T, the voltage dropped while running in traffic, no matter what RPM, the voltage dropped into the 11s by the time I got to the dealership. At idle it just continued to drop. | ||
| Avc8130 |
I looked at the schematic. Pin 21 of the ECM has to be GROUNDED for the harness to CONNECT the 3rd leg. If the ground is taken away, 2 legs of the stator are in operation. So it would depend what the older flashes did with Pin 21. If wasn't used, but was it grounded? ac | ||

Thanks Avc. | ||

Is the anything (parts or process) that differs from the Cali versus 49-state bikes for this stator harness upgrade? I live in Central California. Reason I ask is my dealer has probably never serviced a 49-state bike (I brought one in for track duty.) I know things seem to triggered by the VIN in the HD system, so as long as the are using the appropriate VIN, will they get the correct parts and correct procedures? Obviously, this is assuming something is different between the Cali/49-state harness upgrades. I am just way paranoid after hearing some of the bad dealer related stories here. | ||
| Tpoppa |
The CA bikes have a different flash. I believe everything else would be the same. | ||
| Fresnobuell |
Is it true that when they hook the bike up to do a flash, the system automatically gives them the flash based on the bike it's connected to? IE, the tech does not select the flash (and cannot screw it up.) | ||
| Avc8130 |
More or less. Yes. | ||

Tpoppa I cannot vouch for all the other 1125CR's BUT mine has two that is two headlites not just one.....  | ||
| Tpoppa |
1 hi, 1 low correct? | ||
| Dktechguy112 |
keef, the R's have two lows and two highs for a total of 4 headlights. They are 35w instead of the cr's 55w, but the total draw is more on the R's headlights. | ||

So what is the answer to this problem? 1) Rewind 2) Replace with 08 inc. cover 3) Replace with 09 or 10 and wait and see 4) other? EZ | ||
| Dktechguy112 |
after reading a lot of threads on this, here is what i will do if/when i have a stator failure If my stator goes out under warranty, then i will let my dealer replace it with an 09 stator. If my stator goes out after the warranty, then i will get it rewound. | ||
| Fresnobuell |
Can someone please enlighten me on why low RPMs are harmful and high RPMs are less harmful on this stator issue? And is there a guess as to what the harmful range is (ie <4,000RPM)?? Thanks. | ||
| Dktechguy112 |
fresnobuell, It seems that the stators fail due to heat. The thought is that at low rpms, not enough oil is circulated past the stator to properly cool it. The magic number is 5k rpms, the charging harness cuts out one of three legs of the stator when the bike is below 5k rpms, the goal is to keep the heat down. | ||

Ah, the oil circulation makes sense to me. So without the charging harness, the stator is running all 3 legs (full power?) all the time and its causing the heat issue. am I close? | ||
| Dktechguy112 |
yes, The harness basically only allows 2/3 of the stator to work under 5k rpms, and runs the whole stator over 5k rpms. From what i understand, the oil pump increases pressure with rpms, so when the bike is at low rpms, if the stator is running at full power(aka no harness), it is producing too much heat for the amount of oil flowing by to dissipate. There are only 3 legs on the stator, so when 3 legs are running it is producing full power, which is 520w for the 09's i believe. and under 5k rpms, it would produce 2/3 of that or about 346W. | ||
| Bueller4ever |
I don't think there is a 5k cut off point. Maybe 5k and above a certain temperature. I've seen 14+v at well under 5k cruising, just saying. | ||
| Dktechguy112 |
bueller4ever, the voltage will remain the same when a leg of the stator is cut, it will just provide less current. | ||

Dktechguy - sounds like a plan! EZ |
