My brand new 2010 rmk 8 hit the snow yesterday w/ zero miles. Everything worked fine until after about 1.2 hours of run time. All of a sudden instrument panel went dark, and sled shut down. I would re-start the sled and it would go for about 30 seconds, then shut down again. Brought it straight back to the dealer and told them to make it right. They think its a faulty voltage regulator, anyone else had any problems like this..? My sled has 13 miles on it and its already in the shop.

polaris had a bunch of bad regulators in 09 and 10. they are replacing them with an updated one.

The symptoms of your sled sound like a faulty regulator. There is an updated part number for a new Polaris regulator that was posted here on the Forums. Polaris has been covering the repair for most of the regulators when they have went out.

Thanks for the info. I hope that this is the only problem, and the dealer said they would repair it for free. So at least they are honoring the product

Make sure they replace the ecu also. If they act like they will not then run it before you take it in and let it fry the ecu the rest of the way. I bet if you pull the ecu now and look on the underneath side it is starting to blister and melt, its toast dont let them fool you. Just trying to save you another trip to the dealer.

just so you guys know polaris is doing a 1 year extended warranty on the voltage regulators and ecu's on 09 and 10 600/700/800's. The one year starts from the date your original warranty ends.

This applies to both U.S. and Canada sleds?

Is this not an issue on the 08 machines? I've never had any problems, just wondering.

I am curious about the 08 D8s as well.

I just replaced the 4101731 VR on my 08 D8 163 with the updated 4012930 VR because of a couple of bubbles on the bottom of the old one.

Anyone know if they are having any issues with the updated 4012930 VR?

all you can do is ride it until it fails, mine went out with 9 miles on the sled. Had to limp it out another 4 miles. it would run but only in 30 second intervils. I THOUGHT BUYING NEW, I WOULDNT BE HAVING THESE PROBLEMS, the dealer is taking care of me though and im keeping my fingers crossed that they will make it right

Could you doo all of us a big favor? Find out what number is on your original "Failed" voltage regulator and then let us know what number VR is on the replacement if indeed that is what has went out.

We have a big thread somewhere on this very issue...trying to figure out which number VR's are failing and finding out what the latest part number is.

Yes I will ask the dealer the old part number and the new one that they are installing, The sled is at dealer now sitting because they are waiting on the new part. As soon as it is done, I will find out re post under this Thread

I have also had my VR go out and take out and ECU. You may want to have them look at the pistons because a lot of sleds that had the VR and ecu go out causes the sleds to go super lean and scuff the pistons. I have the updated VR but would be very interested if your VR was the updated one or the older one. Thanks

I have a 2010 Polaris 700 RMK. It has ~250 miles on it.
Yesterday, part way through our ride the dash lights went out and
the headlight dimmed, then a minute or 2 later the headlight went out.
Then shortly after the sled would turn off. Restart and repeat all
the way back to the truck.
After finding this thread, i went and checked the regulator part number.
It has 4012476 on it.
Based on this thread's info i need to take it into the dealer and
have a new updated one put on (4012930).

I couldn't find the service bulletin info mentioned, so....
Are there any other rmk known electrical problems that could also exibit this
problem? Or is my outdated regulator most likely the definite issue?

Thanks for the info!

I have a question. If Polaris know's there is a problem with a part, and also an updated part, to fix the problem part, why don't they have the dealer's replace that part before it fails (and leaves you stranded, or ruins your snowmobiling trip)??????? Or am I missing something? Thanks and think snow!

Alright guys, the dealer could not give me the part # of the old VR that came out of my 2010 rmk 800. " i guess they threw it away before i was able to ask" But they replaced it with VR part number 034-4012476. They informed me that this is the most current VR that polaris is offering. Im hopping that this will solve my problems with my brand new sled. They said that my ecu was fine because the VR failed on the low end of voltage rather than the high end.

Well.... That was my question as well. I brought this question to my dealer to see what they would say and they told me that the reason that polaris is not recalling the part and just replacing all of them, is because. Supposedly, not all of the VR's are bad. Only some of them.... So... To me this means that you ride it and hope that yours is good, and if its not , you hope that your sled is still within its warranty period so it will get fixed for free.

They just replaced mine with the 4012476. Im thinking the same one that had come out of it. They told me that it was the latest most current VR for this sled. I hope they were right as am going on my second trip of the season in 2 days.....

When these vr's go..
Are there signs of it melting before it completely goes??
I understand the ecu will show signs of melting, butthe VR itself??
I'm gonna pull mine out and inspect it.
My voltage reader on dash has been acting funny..
Blacked out at idle, flashing at me underway..
I don't wanna be getting pulled out.
Thanks in advance

I had my VR go out and it was replaced under warranty last year. So I pulled up my service ticket and mine was replace with 4012476. So I went online and looked up and it says that 4012476 replaces 4011731. So I think you got the updated one.

Some have posted 4012930 as the update VR and online that shows its the VR for the 2011 600.

Called one dealer they told me the 4012930 is the latest out. Called another dealer they told me. The 4012476 is the latest out.
I used the part searcher on the dealers website and it told me the 4012930 replaces the 4012476.
I used the Polaris part finder on Polaris website and when I typed in 4012930 nothing was found, I typed in 4012476 it found the part and told me it was the VR .
I believe the 4012476 is the latest out, if that's what the Polaris parts finder site is telling me.

Well my sled now has 4.2 hrs and 65 miles. So far so good after the new voltage regulator.

I had three good deals that I would have bought a Dragon 800, rmk 800, or rmk700, but I'm 68 years old and I'm not going to risk burning up 35 miles from truck, I travel 1200 miles to trail head each time I ride and there is normally no one there to ride with. Hope Polaris gets wind of this. They know the VR, ECU, causes pistons to burn but will still let you venture out.

So why do some dealers have different part numbers for these regulators than other dealers? Like Polaris needs any help in looking bad, but this inconsistency between dealers is unbelievable. I do understand that some dealers are more on the ball than others, but with an issue like this don't you think Polaris would make sure that EVERY dealer had the most up to date information and part numbers etc. Personally I have went through two voltage regulators now. With this last one I had to leave it in the mountains for three days before I could get a new one - only to find out it is the same POS part number as the one that came out of it. Then, because Polaris said that since I was out of my normal warranty, they won't cover the new regulator even though they know they have a problem with the regulator. What a bunch of crap. This is why it is probably the last Polaris I will own. In my opinion Polaris is being very negligent by knowing they have an issue with these regulators and not actively doing anything about it. It has left me in the mountains - anyone else? Why not a recall???

Anyway, so does anyone know what the correct part number is? I am seeing two different ones depending upon what fiche you look at, Carl's cycles or Polaris industries.

Thanks -

Who's your dealer? I thought I read on here somewhere the reg's are covered for another year for the 09/10 models.

On Carl's Cycle parts fiche it has part #4012476 crossed off, and part#4012930 replacing it. I also spoke with a local dealer who still had the 476's in stock, but were waiting for the new 930's to come in. This tells me that 4012930 is the correct part# for the newest updated VR.

I change my VR at the begining of each season and throw the old one in my Pack as a spare 120$ ouch but here are the #'s I have
I am still on the 09ECU although I have the reflashed 10 ecu along with a VR in my Pack as a just in case!! now I hope the stator doesnt go out!!!

08-09 OEM #4011731
installed 09-10 season #4012476
installed last week #4012930

So I think the 930 must be the latest greatest,and No I have not had one fail Yet!!!

How many guys have had VR fail and not the ECU????? I dont know if the ecu goes out the second the VR fails???

seems like some guys get away with just changing the VR?? or do the ecu's fail from repeated starts with the VR failed trying to get back to the truck???

I have now burned through two regulators. The first one lasted two years, and took out my ECU. The second last 6 hours and did not take out my ECU. I now have the latest/updated volt. reg. I know people are having problems with them but I am wondering if there is something else causing these problems. I have noticed now my fuel pump makes a wine noise and I can here it at and idle, could this be a problem. My dealer said its the loudest one he had ever heard. I never had any problems until I got the engine upgrade a year ago from the dealer.

OK, I am not one to whimper and Wynne, but are you kidding me!! I have an 08 800 Dragon in the shop with a fried VR, ECU, etc. Surprise, surprise my warranty is expired and the cost to repair was quoted at roughly $1,300. I thought I would do a little research to find out if I was alone in my plight,(misery enjoys company). The best that my dealer could offer was to trade the POS for a new sled, which makes perfect since, because they are the only ones that can afford to keep replacing parts on it. This recent failure might not be related to the 09-10 VR problems, but it sure smells like it. For what its worth, I will be checking the part number for poops and giggles. I am sure you would agree, Polaris doesn't give these sleds away, actually they very proud of them. I only wish that pride was extended a little further beyond the sell. Any other 08 VR failures out there, or am I just lucky!! Thanks for listening.

What a mess. Has anyone elso noticed that Polaris has cost themselves more money by not taking the high road and doing the right thing with these sleds? So now there is a 3rd updated VR. Why wouldn't Polaris pull the old ones and just send us new ones to save face? With warranties running out, there are going to be a lot of unhappy customers if they have to fork over $1300 each time that $120 VR fails.

Bought a 2010 IQ Shift for the wife new on the floor August 2010. Same issue - dim lights and dash display goes out. Shut down start up fine. Sometimes for 100 yards sometimes all night it would run fine. Found this info - funny none of the dealers have seen the issue around here - nor have they seen the Service Bulletin - SSA-10-01. (Would love to see a copy posted).

Anyway - new part on order after conversing with the dealer. They have been most helpful just wish they were closer than 70 miles away.

Stay tuned - hope this one will be put to bed.

I also was left walking after the voltage regulator issue with my 2010 Assault, about 500 miles on her. When I got home it took me 5 minutes to find out everyone is having problems with these crap regulators. I was excited to see Polaris issued a bulletin and are doing the right thing by replacing these things. Unfortunately after contacting my dealership and Polaris they will not replace my regulator. I tried to get a good answer from Polaris (called numerous times and sent multiple emails) why they would not replace my VR. The only answer they provided was "we found no bulletin for your snowmobile". The regulator that was in my sled was PN 4012476 and I just ordered the replacement PN 4012930 through my dealer. After dealing with their customer support, I'm not as big as a fan as I was a week ago.

after a week at the dealer, i was told that the screw that retains the spare belt holder caused roughly $800 damage in parts. apparently it rubbed thru a wire on the stator which blew the voltage regulator, which blew a capacitor, which blew part of the ecu. the part # on the old VR is 4010794. i'll have to check the new one tomorrow.

so, for the time being the sled runs but the dealer says the ecu will not take a flash. it's running for now but for how long...WTF? i'm no electrician but aren't there supposed to be fuses to prevent this sort of damage? this is on a work sled but it doesn't lend much confidence to my "new to me" '08 dragon 800.
