Gwbarm was right.  It was the sending unit.

Dealer swapped it out under warranty.

Thanks for all the input guys!

Thanks Mech.

Wd-40 and a little more muscle and I still couldn't pop it loose.  If it's that hard to get off, how much fun will I have putting it back on? I'm tapping out.

It is still under warranty and I've been in touch with a mechanic at my local friendly dealer so he has an idea of what parts I may need when I bring it in next month.

Going to Alaska to work for 3 weeks.  I'll have an update after that.

If you find a wiring schematic for 2022 Sector 550 and can share it, that would be great.👍

Thanks for your help!

All 6 of the "locking tabs" look to be the same.  The white piece at 11 o'clock is part of the plastic seal.  I marked it with a sharpie to be able to see if it moved.

Is that what you are talking about?

Mech suggested the other day to "short the wire to earth" 

I ran a jumper wire from the battery, no ground wire, to the red/white wire in the plug.

The instrument cluster lit up, speedo and tach needles jumped, but the fuel gauge did not change.

Time for a new instrument cluster?

"Loosen the lock ring" is the part I'm having trouble with. 

Tried the 2 crossed screwdrivers, the hammer and screwdriver and I yelled all the swear words I know at it.

Won't budge. 

Any other tricks before I take it to the dealer?

Thanks.

I have NOT determined that that is the problem for sure.  

I've been inside EFI Arctic Cat snowmachine tanks several times, so am somewhat familiar with the set up, and am curious to look in this one. 

What do they say about curiosity....?

Wish me luck.

I'm going in! 

Tomorrow.

That's  what I thought.  The old "hammer and screwdriver" trick.

Do you know a better way?

Here's a picture of the top of the tank.

I don't see any bolts to remove.

2022 Sector 550, 414 miles on it and the gas gauge reads empty.  I topped off the gas and it didn't change.

There is no fuse that I could find.  No access at the gauge cluster.

Wiring on the top of the tank looks good, properly connected.

Could the sending unit in the tank be stuck or broken?

Has anybody removed the tank lid?  Any tricks?  

Any other ideas?

Thanks for any help,

Clyde

Water in the fuel.

I refilled the tank with fresh gas, added Sta-bil and heet.  Ran it up and down the road and cleared it up. 

I think it was sitting at the dealer for a year, hence the moisture in the gas.

Running like it's supposed to.

I just bought a 2022 Sector 550, it has 22 miles on it.  Driving down a flat gravel road for 2 miles, and it starts blubbering and missing.  Then it catches and runs fine for a bit, then starts blubbering again.  Then I went up the neighbors steep driveway and it blubbered and then ran Ok, then blubbered again, then ran ok, then blubbered again, I wasn't sure I'd make it.

Got home, let it cool down and then recreated the trip.  Two miles of level gravel road, then it started blubbering again.  Didn't try the neighbors driveway.  Didn't want to have to walk home.

It seems as if when it reaches a certain temp it starts acting up.  It isn't getting hot, gauge reads good.  

Any ideas?  Years ago a Polaris snowmobile was acting up like this and the temperature sensor wire was loose.  That is not the case here.

It seems like an "Ignition Interuptis" scenario, but not sure where to look.

Fuel?  New machine with new gas?  That shouldn't be it.  

Probably going to take it back to the dealer tomorrow, but am hoping to get any ideas from you Hisun guys.

Any ideas???

Thanks for the help.
