So a little backstory on how I ended up here with my 2008 Sportsman 500 HO EFI.
Branching off from my thread HERE and HERE.
I made the jump and bought a brand new wiring harness for a stupid amount of money because I was tired of hunting and fixing broken/chaffed/cracked wires, and seeing how I mainly use this thing for snow plowing, I didn't want to be chasing these things in the winter. Tearing things apart under a carport in the snow and wind is not ideal (not having a garage sucks for sure).
Taking my time uninstalling the old wiring harness and taking pictures along the way was pretty straight forward. Installation was also easy, following somewhat the same route installing the harness. Just take your time and double check along the way. Issues start to begin shortly after.
The first real snowfall of the season I was excited to do some plowing. I did some test runs and everything was checking out fine. No blink codes, idle was perfect, all in all she was running like a champ. Fast forward a few days while it sat there waiting for another snowfall. I should mention I did start it just to keep things moving as it got cold and icy, nothing extreme though.
While I was at work, my GF wanted to do some plowing so I didn't have to when I got home. She knows what shes doing, shes done this many times before, but she sent me a text saying its not running right. F me, here we go again. I get home and mess with it a little, it got dark out so I waited for my day off. It's def not running right. Pulled the blink codes and this is what I have:
So now I am trying to figures these out, under a carport, in the snow, in the wind. There seems to be short somewhere but I have no idea where.
Other than hand warmers and a reverse override mod everything else is cut/splice free. I've disconnected both along with a volt meter I have and same blink codes appear. What could cause this with a new harness? Corrosion? I'm at a loss right now and it sucks.
Any help, thoughts, suggestions, ideas etc would be appreciated. Thank you for reading this long thread.
