2012-2014 Polaris Sportsman Scrambler ATV service manuals

Friday evening went riding, rode for a good hour or so everything was fine. I went to take a short ride to the restroom (less than 100 yds away) and all of the sudden everything flickered and then just died out. Accompanying the problem I noticed the killswitch completely locked up. Once daylight hit took the killswitch apart to find it had shorted out and melted the plastic inside. Has anyone else had anything similar to this and if so what did you do to fix the situation? I have a new killswitch on the way to replace the obvious problem but was wondering could there be a bigger issue at hand. We tested with a voltage meter to make sure everything was still getting power from the battery and as far as we could tell it was.
Any advice/info would be GREATLY appreciated.
Thanks.

Hey just picked up another scrambler 850 was told the tps was bad.  This atv has been beet to hell.  Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it.  When I bought it it would pulse and smoke black at idle and die with throttle.
New tps installed and it won’t run period.  I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps.  Is this normal and if so how should I celebrate it?

Hey so i sold my 04 rubicon and wanted something new so i went to NC and bought a '13 scrambler 850XP LE EPS.  love it the only issues with it when i bought it were a leak in the front tire and the mice had chewed through one of the spark plug wires.  currently have a substitute hooking the chewed end to the ignition coil so itll run on both cylinders however im having an issue finding a replacement coil wire for it and was wondering if yall had any advice.  i need the longer of the two coil wires and i can only find the shorter one online.  will throw up some pics of it when i can

Anyone know what the fuse terminal marked UNSWITCH  does  .  Even with the key off it is causing a drain on my battery and I'm trying to figure out  what that terminal goes to.  It's a 10 amp fuse. If I pull it the "short" goes away.  Thanks in advance.

Had a spark-plug break off, had to pull the head to get it extracted. Where the heck is the timing mark on the crank? Do I need to pull the stator or flywheel to find it? When I pulled the head I had the mark on the cam lined up pretty good but I cant remember if it was perfect and don't want to reassemble a tooth off and have to go back through the bear of pulling this thing back apart.
Thanks guys!
