I have a 2016 canam outlander l570. i have had issues in hot weather with the machine stalling and idling around 800 rpms or no idle. When the machine is acting up the measured voltage at the battery while running with lights on and fan running is approx 12.6 and dropping. with lights off and fan not running machine is at 14.4. The dealership wont work on it becuase it stores no code during this event even though i showed him a video of lo batt flashing across my screen. Also my machine takes a few seconds during initial startup to display anything on the screen when the machine is cold? usually about 10 seconds before i see rpms or speedo….is this normal?
any suggesstions greatly appreciated.

thanks
