Exclamation Rectifier recalled, then stator gone?

Hey guys,

Battery isn't charging (Doesn't change from 12V at idle to 8K RPM) and I am trying to figure out where the fault is. I checked the service manual and tested the rectifier (which was replaced under the recall), and the stator.

The new rectifier is showing 5 mega-ohm resistances across almost all of the 6 prongs. I think the manual listed 0 to 11K ohms depending on the prong. --Failed test.

Next, I've got manual approved resistances for my stator (0.11-0.17 ohms across all three prongs), but about 5V AC across all three prongs at 4K RPM (factory: at least 54V). --Passed one test, failed next.

The charging issue has caused the battery to go out a few days ago, but I put it back on the battery tender and found the battery to hold about 12.8V off the bike (this is within factory settings). After all the rev testing, the battery went down to 12.4-12.5V. --Passed test.

Anyone have an idea if these values seem indicative of anything? I would trust the multimeter measurements (which suggest I have a bad rectifier and stator), but I just had the rectifier replaced under factory recall less than half a month ago, with maybe an hour of seat time since then.

If you've had this happen before, I hope you figured it out-- I'm sort of confused as to why a bike with 8k miles on it might have both failures happen at the same time.

Let me know what you guys think!

When my rectifier went out so did my stator. I replaced both myself but ya I think a lot of the time it's a double wabby if one goes so does the other.

Thanks for the reply. I might end up replacing both for the peace of mind-- I just didn't want to spend extra and crack the bike open if the stator was still good. 5VAC out of 2 of the gray plug prongs doesn't sound right??

As for the rectifier, I don't think Kawi would pay for another one after replacing this one-- even if it were a defective part. I don't know of any spots that will test it for me for free either ($90 is what my local shop quoted me). I'll trust the multimeter measurement and just bite the bullet.

If anyone else has experience with testing/replacing the stator, let me know!

Contact Kawi, they should cover everything. Same thing happened when my rectifier got recalled, and Kawi covered the stator also, just be the calm educated asshole with them. Happened to others if I recall, check the posts from the rectifier recall sticky.

Hey Prof.sqrl, thanks for letting me know-- I jumped the gun and ordered replacement parts (the mosfet rectifier and Rick's stator), but it never hurts to have spares, right?

I'll check out the sticky and give Kawi a call. I'm not 100% certain that the stator breaking down is related to the rectifier, but then again, I've never had a stator OR rectifier go on any bike I've owned, until the '09 6R. Thanks for the heads up!

My stator went bad last aug. took it to the dealer and lucky I had my extended warranty. Kawi replaced it. Don't know what caused the fault though

I just want to update the thread and let you guys know that I called Kawi about the problem. They were great about it (I think the rep that picked up every time was named Tim). I didn't have much time to deal with this issue since the recall service last year, and Kawi's condition was: "If it was an issue with the recall, we'll pay for everything."

Sure enough, the stator/new rectifier had burnt out together, and the dealer worked with Kawi to get it working. I haven't gotten the bike back, but I figured I'd put it out there for the record.

awesome, it's nice to hear that the dealer and Kawasaki were able to work together and get it replaced at no trouble to you. Gives me faith in the company :P

So besides your battery not charging did the bike make any abnormal noises to alert you that something is wrong? Glad you got it taken care of by kawi.

No noises that I could tell-- it was idling in my garage and just shut off after the lights dimmed a little bit. I suppose a bump start wouldn't have worked, so in hindsight, I'm lucky it was in my garage and not in the middle of the mountains!

I tested rectifier and stator (original post) and found both to be malfunctioning. The shop mechanic said almost two arms (wire wrapping) of the stator were totally melted. I felt this was out of out of the ordinary, considering the age and mileage of the bike.
