Heres an update guys
Ended up receiving for free a brand new battery made by interstate. Fully charged, a professional voltmeter read 12.9V from the jump start posts.
Then, I removed the grey clip from the voltage regulator and tested both negatives against the center positives, and both of them read 0.08ohms. If I compare this to what you guys posted, its nearly half of what it should be.
Never got a chance to try it out since the new battery, wanted to report first.

Well that measurement does not sound too promising. I would still go through the steps to check the charging system as Len stated. Here is the link to the service manual. I have attached a copy of the Charging System Checks.

So pretty much, the only thing I havent done is run the sled and check the voltage then right?
Im also going to try going for a ride near home tonight and see if it dies on me again. Ill report this evening with the voltage results.
Thanks for the link!

New battery, same exact thing, went for a while, then died, code 46
Im almost sure its the stator now.

It is possible that it is the stator. Good luck with your stator swap.
But, it could also be the voltage regulator. But, your measurements make the stator most likely.
Too bad you did not do the voltage check before buying a new battery. Probably could have saved the cost of the battery.
You may want to make sure the battery you use is fully charged before you reinstall it. The sled typically can not recover a fully discharged battery.

Lukily I got the battery as a surpise birthday gift, and before installing, the battery read 12.96V, sounds about right eh?
Also, was just wondering if you knew whats involved in changing out the stator, do I have to remove the motor? My dealer had a RS venture with a bad stator last week and they had to remove the entire motor, it was a huge job.
How tough is the voltage regulator?, is it suseptible to snow buildup or impact? I had a ton of snow in there from powder riding one day and also had a stick puncture through the plastic just above the edge of the skidplate but it did not penetrate all the way through to the regulator, but it was about an inch from contacting. It was one of those dry stump sticks. Although it seems likely that the stick penetration might have something to do with this, I am unsure because I put on another 200kms at least before having this issue.

The reasons I am a bit hesitant to tell you "yep, it's the Stator" are the ohm readings you got off the stator were the same on both coils and the accuracy of your meter is not known. Your meter could easily be off 0.1 ohms. If your meter is off, you could have a good stator.
The stator is a big job. I am pretty sure you have to pull the motor. You do have to have a Flywheel puller to get the Flywheel off. Once you get the Flywheel off, the rest is simple. You might ask the dealer's Tech what is involved. I have pulled them on many a Cat. But, they had a lot more engine compartment room.
It sounds like the new battery was fully charged. Once you installed it, did you by any chance get a voltage reading while the machine was running? Or was the 12.9 VDC reading when the machine was running?
I am wondering if your "stick incident" damaged the wiring to the voltage regulator? I forget, ... Did you check the connection and wiring to the voltage regulator? Could it be possible the stick damaged the wire or connector. Is the connection to the voltage regulator solid? I would check the wiring from the Stator to the voltage regulator.
And, then there is this damage to the Voltage Regulator itself. I am suspicious of that.
Before you attempt a Stator swap, you might want to consider trying this:
Recharge Battery. Unplug stator from harness. Start Sled. Test voltage from Stator's Center Pin to each side pin at ~ 3000 RPM . Then measure voltage across the two side pins at ~ 3000 RPM. These measurements will most likely be AC voltage. If you are seeing > 16 VAC (probably more like 20 VDC) then I would say you are getting good output from the stator. If you are not seeing this kind of voltage, then the stator is probably bad. Doing this, puts you up in a measurement range that the tolerance of the meter is insignificant.
Let me know what voltages you see.

The meter I use is one from my friends instrumation course at college, so im not sure of its accuracy, but im assuming its decently accurate, is there a way to check?
As for the actual stator itself, I have pulled many with the flywheel puller on yamaha triples, but never a 4 stroke. I was thinking of just getting the dealer to do it if I end up needing a stator and if its covered under warrenty. That way if the motor has to be pulled, they can install solid motor mounts from turbo addiction ( To fix my serious motor alignment issue)
Before installing in the sled, the battery read 12.96VDC, I never did check while it was running. I will do what you suggested tomorrow, but I was just making sure that now I will be testing voltage at the stator clip in AC compared to earlier where I was testing resistance in ohms?
Also, here is something interesting I found under close inspection tonight, one of the wires in the clip had pulled out a little. I put the wire back into the clip and did a resistance test when the battery only had 12.2V and still got 0.06ohms, which is the same as before.

Given the connector with the wire not fully inserted, I would first reconnect it, install the recharged battery and test the voltage across the battery, while the sled is running. That could have been your problem.
If the sled is under warranty, definitely take it back to them to do any stator work. Actually, I am not sure why you are spending all the time troubleshooting it, if it is under warranty. ??

I just didnt want to spend any money on labour if it happened to be something stupid.
After plugging in that clip, the resistance from the stator was still very low at 0.06, even with the battery at 13.5V just sitting there.
Its going to the dealer today, I took the powercommander and ignition module out just incase they dont want to warrenty it due to something aftermarket being there.
Ill post here what it turns out to be!

Did you test the charging voltage with it running? Did you test the charging voltage after you took out the two modules?

I tested everything over again after taking out the modules and everything was exactly the same, so hopefully the dealer will figure this one out!

Dealer put in a new stator under warrenty.
However, they sucked at putting the sled back together, turns out they didnt even come close to putting the airbox on right, it wasnt even lined up with the throttle bodies and they yanked my electrical out of the headlight unit. Its I good thing I re check any dealers work, they always miss a bunch of stuff.....
Went for a 400 km ride yesterday to elliot lake, and had no problems!, runs stronger than ever and my hand warmers are actually hot!
