Is this stator burnt?

(I'm not sure where else to post, since this is only my second post )

Last week I got stranded at the gas station. My '08 Versys (28k miles) wouldn't start, even though I left with a fully charged battery in the morning. After a battery charge, it started again without problems.

Checks I did:

* With the motorcycle off, the battery reads 12.6 V
* At idle the battery reads 11.9 V. Revving doesn't change the voltage
* Alternator output at 4000 rpm is about 5 V (AC), between any combination of the three leads, while it should be over 42 V, right? Revving doesn't really change the voltage.
* Resistance between any combination of the alternator leads is about .6 to .7 ohm.


So I took off the alternator cover and this is the stator I saw. Could that black piece over there be the cause of the problem?

that black spot looks like where all the smoke is leaking out.
I tried an aftermarket unit that was cheaper (and looked cheaper) and had the cheap plug melt.
I now have and oem stator back in my bike.

FYI your stator is toast

You have 3 options:
#1 If you have a bike wrecker around, take the stator with you, a KLR 650, Ninja 650 some years , will all fit and are identical as to Delta connected and turns ratio is the same. The stator you posted is one of the first MK-1 designs. if you could, can you post a picture of the other side of the stator, particularly around the area of the leads. I have included a few links, with pictures and will explain here what to look for in a used stator. Newer versions changed the location of the crossover connections to what I refer to as the back of the stator, which is the side you have posted, and had only the delta connections on the front ( front being lead connection side). The reason is it was discovered that expansion and contraction of the copper caused a short between the delta line connections and the crossovers. By moving the crossovers to the back, 15 connections were moved.

http://www.kawasakiversys.com/forums...1-post299.html this is a MK-1 like yours, failed at the delta connection, short between a line connection and power pole crossover connection. look for a stator like this one; http://www.kawasakiversys.com/forums...6-post188.html the lead/ power connections are closest to his hand, the side shown is the same side as your picture or what I refer to as back, but this one has the crossover connections on it.And that is what you want, also if buying used, make sure they have tested it using a LCR meter or can prove it works.

#2 Buy a new aftermarket china stator ( which is Y or star connected and has roughly 65% of the copper that a Delta has because they cheated and didn't change the wire size equal to two 18 gauge wires of the Delta but stuck with a single 18 gauge per lead out. Typical price for $100, and install a used Polaris series regulator, total out of pocket should be around $225 Canadian , this will last equal to or better than a new OEM Delta stator with shunt regulator. One seller of these on Ebay and in Quebec is RMstator, you get what you pay for. The reason this works is explained by me in one of my Polaris threads in How To forum.Just buying the China stator, expect it to fail within a 2 year period, again the reason why it works using a Polaris series regulator has been explained by me.

#3 Buy a OEM stator for around $400 , possibly you may also need a new POS shunt regulator, and expect this to also fail at some point due to the shunt regulator.

Thanks! Which aftermarket stator did you buy, and how long did it last?

Thanks for responding! I'll definitely have a look at the links and the posts you mentioned.
I took some photos of the other side of the stator. It looks quite charred.

I will also have a look where I could buy an aftermarket stator around here.

First thanks for posting, if you remove the mounting clamp, expect to find possibly one wire burnt off from one of the leads, this is were the short occured, this is a very common thing on the OEM stators before they changed the crossovers to the back of the stator.

As to aftermarket, many are Y connected , the way to know is to look for 3 magnet wires joined in between two of the poles, also the spacing between poles is larger than original because of less copper. They will output the full 330 watts however expect them to burn up, as the conductors connected to the leads out are carrying twice the current of OEM, however
if you install a Series regulator, the stator is never going to running at more than 60% load on a continuous basis, plus a series regulator the output voltage is clipped at 14.2 VDC, so you should never need to worry about destroying the ECU or blowing bulbs, like a few have had happen with the OEM Shunt. Unfortunately Polaris caught on to us motorcyclists using their series regulator and doubled the price in November 2016 . So now good used Polaris is what I recommend.

Stator Various options

http://www.kawasakiversys.com/forums...acement+stator this is a honest view of Ricks, I stand behind this review and would buy a Y connected China stator before I bought what Ricks claims to be Delta wound that they supply

https://ricksmotorsportelectrics.com...-Stator-21_227 You be the judge after reading the thread, wouldn't buy unless I had no other choice and needed it immediately.

RMstator out of Quebec the second best bang for the buck for new ,provided you install a series regulator, as like all but a few, it is Y connected with 60% copper

Seller SVS I have dealt with them before , if the photo is what they are selling it appears to be Delta connected and wound, I would ask them before buying if it is Delta wound and the same as the photoElectroSport ESG638 Stator For Kawasaki ZX-6R / ZX6RR / ER-6N / Versys 650 This would be your best buy if it is Delta wound for a new stator As have a close look at their posted photo, cross over connections are on the back as I recommend!! Looking at the photo, if that is what they are selling, no doubt that it is Delta Wound as there is no space between the poles, and appears the same copper density as OEM, so This would be my first Choice if you followed through with my previous advice

A link to a review of someone that purchased a ElectroSport stator for a Honda in 2006 and had failure, since I have tried to find someone on this forum who has reviewed this unsuccessfully I thought I would add this link
http://genebitsystems.com/david/Moto...torfailure.htm


Here is a used one with the same crossover connections on the lead side as yours that failed, my opinion would be if you could get it for $60 it would work, otherwise

Wow, thanks so much for all the information! I really appreciate your help. I will have a look at the options.

Rick's lasted less than 3000 miles before I smelled burning plastic and voltage said goodbye
