yes. the cover can be a lil tricky getting off, there if you read a few messages above you will see that I have a guide on how to remove the cover : )

I just got off the phone with Gary at Custom Rewind, $140 to rewind your 09 stator, includes shipping. 2-3 day turn around. Or you can spend a grand with your local Harley dealer when it comes off warranty. Gary's accent is lovely, you just know the Bar-B-Q near his place has to be good...

Nice, a rewind seems like the best alternative by far. I would love to get the stator rewound to the '08 spec and deactivate the harness...therefor saving my battery in the long run. I suspect Gary is going to get some business as more bikes come off warranty. Looks like we have a vendor!

Theres two of us out in OZ going down this path ..

just a question about re fitting the stator to the cover ..

Have you guys been using the silicon "black " to hold the cable from the stator down to the ignition cover ?? ??

Will be taking pics of the dead stator, new 09 stator (being rewound and pics of post rewind ...

It has been suggested that "gluing" the wires down interferes with oil flow and cooling.

> Get this, I ordered a new rotor/stator nut so i can retorgue my rotor to 300 ft/lbs to get rid of a lil knocking noise (diagnosed by Michael R from you all know where : )) anyways I ordered it from chicago HD on 11/14/2010, next day is was on special parts ordered. I HAVE YET TO GET THAT NUT. 4 months and going. this is stupid, and before that was a gasket for the ignition cover which took 4 months as well.

I think it's Chicago HD, which is very slow. I ordered some parts from them 4 weeks ago, and there still no sign of them. I called twice, and both time they said that they "fell down with the orders". I wouldn't buy from them anymore, and I don't recommend them. Way too slow. I would have gone to the local dealer instead, though it will add 10% and a tax.

My first and only order from Chicago took about 3 months. Who knew it would be so hard for them to ship a few XB oil filters and gaskets? It is something they should have had on hand, assuming they actually change the oil in bikes that come in. I usually order from my local dealer or Badweb sponsor Precision Harley. Sometimes things are out of their control and it takes HD a week or two to ship parts, but they at least keep me in the loop and don't charge me till I receive it.

Cycles the battery and I don't want to be replacing batteries after warranty is up. All I want is my 09 charging system to operate like my 08 charging system...so I figure if we can get the stator output to match, there's no reason to keep the harness at all.}

I am definitely no expert here so I am asking this because I don't understand, not because I am being argumentative.

From what I understand, the harness update shuts down one leg of the stator leaving two still running. That means to me that the battery is still charging.

How does that cycle the battery?

Ratsmc - you are correct in part, As I have read in other posts I understand that the harness mod shuts down one leg of the stator under specific conditions, predominentely that the engine rpm is below 5000 rpm due to a lack of cooling from inadequate oil flow at lower engine speeds.
I also understand that when the engine is cold all three phases of the alternator are used.
I would have liked to see a definative logic table for parameters that need to be satisfied for the third phase of the alternator to be used.
What have HD got to hide?
I still think we are being treated disgracefully and that the stator warranty should be extended for several more years. If there are no/low number of failures with the harness fitted what have HD got to lose?

Dirty_John...hmmm logic table. Here's what I know. After the harness mod and new stator for months operating at 14.2 on start and 13.6 regardless of temperature. Two weeks ago went for a 280km fang and next day voltage began to drop in traffic...Oh no:-(. From 77degrees C where the fans kick in, the volts are 13.9. She loses 0.1 volts per 1 degree of temperature rise. So at 92 degrees 12.4v. It's almost linear. How and what controls this relationship, yet to figure out. Boogman reckons my stator is dying:-(.

That information has been posted on here several times - so apparently they have nothing to hide..

If I could be bothered I'd do a search and repost it - but I can't (be bothered) - maybe you should?

BTW - if you can find an alternator on your bike, you don't own an 1125.

If you add in all the componenets (particularly the stator and VR) then you have the components to build an alternator...which I am sure is what you meant to say..

The harness upgrade reduces charging capacity when the 3rd let shuts off. This puts more strain on the battery, which will shorten battery life.

Let's face it, the harness upgrade was the CHEAPEST solution that HD could come up with. It's OK at best, definitely not ideal.

There are trade offs. When idling in traffic with both fans running, I regularly get a battery light. The stator, battery, and VR have already been replaced under warranty. I cannot use my high beams without the battery light coming on. I have given up on adding any electrical accessories. After a ride the battery is NOT fully charged, it needs several hours on the tender, this was not the case before the harness upgrade.

I would rather replace batteries than stators, but I would really rather have a fully functioning charging system. At least as good as the 08 system.

I don't believe so - it was after all a "voluntary upgrade" but it will make the stator even more prone to heat damage and failure...

Just wanted to say that I'm experiencing the same exact thing. Stator and VR replaced, volts stayed around 14 for weeks, even with fans on. Now dropping into the 12's again once fans kick on. I'm sure this stator will die just like the original, that's with the stupid wiring harness. The 09 stator is just cheap junk, getting mine rewound myself this time and removing the wiring harness fix.

I have found a reputable stator rewinding company here in the UK so when the inevitable happens I know who to turn to, now to buy in the gaskets etc needed to do the job.
In the meantime it will not stop me looking forward to the summer riding the bike as it was intended to be ridden - if the stator packs in then so be it, it can be repaired and it will be rewound for about 450w to 475w output bearing in mind the number of poles is different between the 08 to the 09 model year, the bike spends most of its time on a tender anyway.
I have fitted the FH12AA voltage regulator as a precautionary measure after reading other posts on this forum and woudld suggest 09 owners consider doing this as well - anything to improve reliability.

This happened to me last night. Tell me what you think?

I was going down the road, and the lights and the instrument panel started going out.

First the headlight, then
Then instrument panel
Then the panel went totally off, with a message, that there was an outage.
The front headlight was on dim, like a parking light.
The fans started running all of the time.
I could smell fuel, and the bike was running at a higher rpm than normal idle.
I turned around and went back home, not knowing if the taillight was out or not, since I didn't want to get stuck somewhere.
I came home, and the bikes fans would not shut off for a long time, the headlight was on dim, and the instrument panel was off showing outage.
Finally the fans went off.

I came back out later to turn the ignition on, and the instrument panel came back on as normal?

I have had the wiring done at the dealer last year.

Stator problem? REX

Could be - but it could be any number of other things. Did you do any measurements when it was playing up? It could be the VR, but there are a few other things too (loose connections, bad earth etc).

When it came on as normal had you done anything to it or just left it alone?

What did the voltage display say then?

Voltage in the 12s is typical for the harness upgrade. It doesn't necessarily mean your stator is failing. Voltage in the 12's is not normal, however, for a properly setup charging system.

Even at hwy speeds, with both fans running my voltage is in the low 13s or high 12s. When the fans stop the voltage will predictably climb to around 14.1.

At idle my voltage settles around 12.4. When idling in traffic with both fans running voltage will drop below 12 and the battery light may light up.

This doesn't mean the stator failing. This is the band-aid harness upgrade doing it's thing.

It's been posted? I have missed it. are you sure it's hasn't been someone's educated guess?

If it's the real deal, can someone link up where it's been posted, please?

>>>"I would rather replace batteries than stators, but I would really rather have a fully functioning charging system. At least as good as the 08 system."<<<

A properly wound stator along with the correct voltage regulator would be a good start, maybe just the correct voltage regulator might do it.

My voltage regulator had to be replaced under warranty, and HD put the exact same regulator as stock, obviously it is not the right one if it burned up so soon.

I have had 2 stators and a regulator replaced on mine.

The dash went dark and displayed outage. When this happens, I don't believe it shows wattage. If it did, it was too dark. It was at night. I was just worried about not getting hit by other cars not seeing me, or the bike dieing while I was at speed...

I don't think you understood my post. After stator replacement, for the first 500 miles or so, I never saw the volts drop below 13.6 volts, never, not at idle, not with a hot motor, never! Now it's dropping instantly to mid 12's at idle. If you think that's normal with the wiring harness, then I say pull your wiring harness and your volts should go up, but they won't.

I would bet your stator will die soon. Once it doesn't get above 12.8 at speed, then it's shot.
