Just wondering if someone has there kq available to test their working stator. I was plowing in the dark the other day and at one point I could smell something cooking, the next morning the battery was weak when first trying to start it. The service manual says it should be putting out about 60V AC, I was hoping someone could test their stator and give me that number, right now at idle I'm around 35V AC, there is not much of a change at 5k rpm. The plug for the stator is on the left side of the quad under the upper black side plate. It's a plug with 3 yellow wires in it. I can get pictures if needed, but my internet in the bush isn't the best for loading pictures.

So with an output of 35V AC I'm thinking I cooked a part of my stator. When idling the battery shows it is charging, but if I put on all the night lights the voltage drops to under 13.5V on my battery and keeps dropping. I have a spare stator here that doesn't look burnt, but I was only planning on opening up that side of the engine in the spring when it warms up.

Are you using a wench to raise and lower your blade?/ cause that alone uses a lot of voltage/amps I plug mine in every time I’m not using mine..

Yea, but I have a larger car battery on it because of the constant winch use and for the fact that I plow in the dark. It's been on the quad for 5 years now.

O’tay...

If its charging at idle and drops on higher RPM it sounds like the regulator/ rectifier. You should have fairly close voltage from each stator wire. There are 3. I put a "Blue Elf" regulator on my 13 KQ750 off Amazon. I know, the dreaded aftermarket from Amazon. BUT in this case it's been on the bike for over a year and hundreds of miles and still works like it should. Right now it's under $30 bucks on Am. . If and when you do replace the regulator rectifier add a separate ground wire from the Reg/Rec to the battery. There is a common issue with the Reg/Rec losing ground and burning it
up.

I'm thinking I burnt half the stator, as it is only putting out 35V AC instead of 60V.

I'm going to get my spare rectifier and see if that changes anything, it's going to be cold out in the back shed with the parts bike. 🥶🥶🥶

Swapped out the voltage regulator today and it seems a bit better but I'm still thinking I have low voltage from the stator.

Well after further investigation I found a video on how to test a 3 phase voltage regulator, I did get good readings as far as voltage direction, but did get a lower reading on one of the 3 diodes. I'm still not sure if the stator is putting out the correct voltage. I have to open up that side of the motor this summer anyway, I'll have a look at it then, just wish someone could test their's before I dig into this.
