Do I have to buy a Pep Boys cheapo unit or go to the dreaded dealer to shut off the SES.

I accidentally left the snow plow in cab controller 'on' for a week and when it snowed Friday the batteries would not even light the interior or under hood bulbs. After charging it struggled but got running; yet that light is still on.

Question: Is there a way I can shut it off? Multiple start/runs? Pull a fuse?


I know.
