2012 Pro RMK 800 cuts out and dies

[lemonf7]

I have a 2012 Pro RMK 800 with 500 miles. Yesterday, around 10miles into the ride, I felt the engine cut out while cruising down the trail. it was barely noticable at first, but the more I drove, the worse it got. It got to a point where it was stalling out to the point that the sled would hardly move and it eventially died completly and would not restart. I let it sit for 10 minutes, and then it would start and run fine for a couple miles and then start the cycle over again. The worst part is I had to be towed in by a Cat...
It definately seems like an electrical issue caused by heat. the more the sled cools down, the longer it will run before stalling issues start happening.
I have No check engine light, temp is normal, and as far as the TPS issue that many people are having, the symptoms dont seemto really match up.

I dropped the sled at Polaris West this morning, I hope they can duplicate the problem and get it sorted out. It almost feels like a stator issue, like some of the older cats were cursed with.

Any ideas?

sounds like a voltage regulator failure. If so, it could also take out the ECU.

Keep us posted.

Voltage regulator=ecu, or stator?

 

[lemonf7]

neither. voltage regulator is mounted on or around belt cover I think.

sounds like a voltage regulator. yes its mounted on the belt cover in front of the oil tank.

Is there a way to test the Voltage regulator?

I had an '09 do the same thing and had my bro-in-law's '09 700 do it this weekend too. Voltage regulator and if you keep running it, it will cook your ECU. I would have them warranty the ECU anyway, unless they can prove that 0 damage was done to the ECU.

So when it cooks the ECU, the sled doenst run at all? I will mention it if it turns out being the regulator. I talked to the service manager at my local dealer. He said that the gauges and lights usually go out before the engine dies on the regulator problems that he has seen. I didnt notice anything erratic with lights or gauges.

Relay protects gauges and lights and those go when the relay goes bad. Your dealer doesn't sound too bright.

Have FUN!

To test it, pack it with snow and if she fires and runs good for 10 min then it's the reg. happened to me

Update,

I got a call from the mechanic at Polaris West today. He is claiming that the TPS was causing the problem. He claimed there was a TPS code set. He said there was moisture inside so he replaced it. I am skeptical. I didnt notice the check engine light come on, and I was watching for it. He said he was going to try to put some miles on it tomorrow.

Im keeping my fingers crossed.

That has been a pretty comon issue. I'm betting your mechanic is right on this one. Have a great ride.

So was it the TPS? I'm about to take mine in for the third time now for TPS issues and this story sounds exactly the same as what happened to me except I was towed by a doo. I just had a BRAND NEW TPS installed and it didn't even last 30 miles. Such a wicked sled but this is driving me nuts!

Ok, here is what is going on.

I called Polaris West yesterday because the mechanic told me that he would put a few miles on the sled last saturday to confirm that the problem had been fixed.
I asked the mechanic if he had had a chance to take it for a spin. He told me that he is too busy to ride the sled, but that is the only thing that ever goes wrong with the Pro's and that Polaris doesnt pay them for test rides.
I explained to him that I am from Minnesota, and that I will be driving 1000 miles to ride that sled this weekend, and if the problem is not repaired, that i will have wasted 2 days off of work, $800 in fuel, not to mention time away from my family for absolutely nothing. He replied, "if you are willing to pay me $80 per hour, then I will ride your sled".

I guess I shouldnt be pissed off, because there is a possibility that the TPS has fixed the problem. However, The issue I was having was definately heat related, And of all the TPS posts that I have read, None have described my sleds symptoms.

I had a similar problem and eventually it was traced to a stator wire that got rubbed raw and was shorting out periodically. My wife towed it in once with her 600 Pro and I barely made it out the next time. It was fixed by replacing the wire and zip tying it up where it would not happen again.

I lost a voltage regulator at 41 mi, took us a while to figure it out, as the sled ran perfect every time we had it hooked up to the computer. It was the car battery that was hooked up to the harness that was providing the power. My sled kept throwing a TPS code as well. After replacing the regulator, TPS code went away, and I have a regulator on order in case it ever happens again.

I would think a little 10 minute test run wouldn't be too much to ask to ease your mind considering they have snow out the front door. Some dealers know how to develop a customer base and some will never figure it out.

Sounds like your dealer has the same bad attitude as a dealer that I dealt with couple of years ago. I found a new dealer...

That was my post....the last few rides I actually took the ignition coil off and zip tied it up....cut a water bottle and packed it with snow and it ran all day without doing it. Packed it a few times throughout the day. Now I have a new reg

Bought 3 new sleds from Polaris west and wont buy another because of THAT atitude.
