Hey guys and gals, I have a 2012 rzr 570 that seems to only overcharge in the cooler temperatures (hunting season) the dash flashes OV 17.? and you can sure smell a battery boiling. It has not done it all summer but seems to get all messed up while I am hunting. Some background I have a group 31 size battery mounted in the cargo area…thought this may be the problem, but it only does the overcharge on occasion. I heard someone say there was a charge relay hidden under the machine somewhere that is possibly sticking once wet and maybe freezing (not sure). I did check the overcharge and it is charging between 17 and 18 volts…any ideas would be great, I am stumped, and hunting season is just around the corner.
