Loose plug / wire

I have a 2013 renegade 1000 that is consistently giving a communication error on the dash. I’ve check the battery terminals and cleaned them. Battery starts well. Anybody know proper voltage? I bought this used and it seems the previous owner liked to swamp it and not maintain it. I also checked for water in connectors in wiring harness. Seems like all are dry and clean. There are 2 plugs up front not connected to anything. Can anybody help identify this plug? Is it supposed to be exposed? Could this cause the comma error?

2011 850 Touring Belt Engagement

I have a 2011 850 touring that has a little over 3,500 miles on it and has been relatively trouble free. I've noticed recently that whenever I go to take off, I have to throttle up pretty good before the belt engages. As time has went on, it gets tougher and more frustrating to ease into throttle and get a response. Could this be a symptom of a wearing belt or clutches that need to be cleaned?

Changes through the years

I have recently bought a 2008 800 Sportsman. This forum has been a great help, particularly in deciding how to maintain this thing. I've noticed there seem to be many major changes to the basic mechanical build of these machines as the years went by. Can anyone lay out the important changes/improvements at what years in the Polaris line? For instance, when did the radiators get mounted up high? What were the changes in the drive train? Just wondering, good stuff to know if I decide to buy a newer unit.

Elka shocks on Defender?

One of my front shocks started leaking oil on my Defender Cab model. Elka Stage 1 shocks are very close in price to the OEM shocks. Has anyone tried them on their machine. I like the idea of having more adjustment than the factory shocks.

Improvements from 2017 to 2018

Shopping for a new machine, focusing on the 570 X2 but also considering a base 570 with EPS.

I'm wanting to make sure I have captured the improvements from 2017 to 2018. Here is what I believe they are:
1) EBS engagement is less abrupt.
2) Additional heat shielding on the right side of the machine
3) Stronger axles

Any comments on this would be appreciated!

Coil Spring upgrade

I'm finding that my 2018 sportsman 570 SP is need of a heavy duty spring upgrade. I have adjusted the preload to max but still find it to soft, I use about 40% of travel just sitting on the quad. My payload is about 400lbs and I'm a aggressive rider. What would you recommend? EPI is the only one that I could find and they say the front and rears are the same.
