This is the first I've heard of the cables being to short. Do the latches work securely? I've heard that you can adjust the hinges to make them tighter. Maybe they can be adjusted to make the cables work better too?
Where they mount to the atv, make sure the tabs are pointing forward. Where they mount to the lid, make sure the tabs are pointing straight down. (when the lid is open) That makes them as long as they can be. Any other position really shortens them, and they aren't any too long to start with.
When we opened all three quads front lid cover on the show room floor, they wanted to close all by them selves.
I made sure the 2 cables were as long as could be.
If I opened them real slow and pulled on them in the open position, they would stay open, just barely.
If the quad was on any incline at all, the lid would close for sure.
I'd hate to jury rig on the brides new machine so soon ((((((((((((
Adding a rack extender will help a little. These lids are so light that any extra weight helps to keep them open. Don't know why Polaris put such short cables on them. Another 1/4"-1/2" would make a big difference. How much longer is the cable on your 850 storage box? Maybe you could get a couple of them.
When I took my lid off to install rack extenders I noticed that the cables coiled up. When they want to coil it pulls on the lid. You might be able to "unwind" them a bit. Also make sure that you're giving them the most length you can by pointing the eyelet down from the lid and to the front on the frame.
I know what you mean by the cables being just a tad short.... my 800's were also. So, I directed the eyelets to point forwards and down and untwisted the cable (all as mentioned prior) before reinstalling. Then after the addition of the rack extender it helped allot too.... but is still a little touchy!
I'd guess though that they are the length they are so the lid doesn't ever extend and hit the brush guard (if / when installed) and create pressure to break the lids plastic hinge pin!! Usually things are done for one reason or another.... even if it isn't apparent when "stock".
If it's a big issues, I'd simply make new cables to your desired length out of electrical eyelets and braided cable or even jacketed electrical wire.... easy fix - easy money!
I'm thinking about getting rid of my 570 for an 850 Sportsman. I don't need a brand new one, unless a heck of a deal. Does the 2018 have the same updates/upgrades as the 2019 and 2020 models?
I'm not looking for the top of the line model, whatever the most basic model that has power steering...
