After leaving my Outlander L 450 parked for a week (ran great prior), I went to start it up and it turned over once and then everything cut out… The quad seemed completely dead until I wiggled the battery connections… I cleaned the battery terminals even though they were not very dirty. The quad would start but kept stalling out and said "Low Battery Voltage" and then appeared dead again… I finally got it to stay running and drove a few minutes down the road and then it backfired, went to limp mode and CEL came on, but only for a few seconds… Now it seems to be running as normal but I’m worried it will act up again when I’m deep in the trails.

I don’t think it’s the battery. I’ve had the quad for about a year with 650km on it. Everthing is stock… no winch, no after market lights, nothing.

Any suggestions?
