Any progress update on the stator problem?

HI Yamahog, Thanks for asking!
I chose to find a used but like new stator so that I could be sure it was the oem type. I could see actual pictures from an ebay seller and it looked to be coiled in the box and new yet. It may be a new-old stock or maybe someone bought it and installed and found it wasn't their problem? Anyway, it had to come all the way across the US from West Coast to MI and there has been a delay. Should have been here yesterday and is somewhere in Detroit but didn't move at all today.

The strange thing is that when I posted last, the kids would drive the quad around the house a few times and after 2 days of doing this the battery would be dead. I would charge it over night, then repeat and then a few days later it would be dead again.

Then a new problem showed up. The starter makes a bad screeching sound. It seemed to be only when cranking and it did crank and it did start like normal. I couldn't be sure if it was coming from the starter motor itself or from the bendix. Often the bendix screeches when it engages or disengages but this screech seemed to be while cranking (only). So I ordered a starter. If I pull the magneto cover then the starter has to come off before hand anyway.

then this week I noticed the quad was getting used every day and it wasn't getting charged anymore. In fact the battery had enough juice to start it every time. What? did the short to the one leg of the stator unshort itself? Does this somehow relate to the starter shriek or bendix issue?

So the plan was before opening the magneto cover to retest my current stator. If somehow it magically fixed itself I think I'll swap the starter and then see how it goes. If the bendix is bad I believe I have to open the magneto cover then for sure to fix that and if the magneto cover is open then I might as well swap the stator too?

Ugg, always something...

Even if the stator problem seems to have somehow resolved itself I’d have to expect it to recur. I think I’d switch it out but good luck with whatever you decide to do.

The bendix is in play during starting, fyi. I'm thinking you might've jumped the gun on ordering a starter, shoulda ordered the bendix. Much more likely that's where the screeching is coming from

No gasket needed. Only use an oem stator. Rest are China junk. Just use a good gray rtv. Hondabond is good. Just need a real thin layer and I always apply with my finger.

Completely agree - I've been down the road of replacing it 3 times because of faulty chinese junk.

Yes - the first 2 came from eBay

Be careful on that one -

yes, the ebay ones are non-descript, thinner wiring and do not have the same coating on the copper windings that encircle the round stator. The OEM ones have heavier gauge wire and have a gray rubber look coating that looks like melted plastic that encases the copper windings. They are pretty easy to tell apart. This was the oem one and the box was in the picture but the picture on ebay didn't let me see the part number. I'll definitely double check that.

Thanks for the tip about the Bendix. The service manual was a bit vague about how to get to the bendix, or how to test if it is functioning correctly, or how to replace it. It has one picture which is not the best. I may have to figure that out on my own. Good call on having a Bendix on hand if I get that far. They also seem to be fairly universal parts as most all the Bendix in the various can am bikes all look exactly the same.

Someone above mentioned using Hondabond for the RTV. I found two kinds one ending in 4 and one ending in HT for High Temp. I ordered the HT one and hopefully that is the correct one.

You have any luck fixing your problem?

Yamahog, I haven't started the project. Mainly because so many other things are fighting for the top of the to do list... and, it is working without issue. The starter screech stopped, the battery is staying charged and it seems to have corrected itself. I know that seems impossible, or at least is a problem that should be expected to come back again.

My next step if I can get a 2nd person to help me is to retest the 3 wires off the stator and see if now I have proper production of AC volts down all 3. If so, I'll probably return my extra parts (hold on to the stator) and see how it plays out.

Brief update, went out with my son and tested the leads again, same result, 2 are charging one is not. Somehow battery is staying charged. I guess I will have to tear into it at some point still...
