I have a troy built riding lawn mower & tried to recharge the battery it almost started after being on the charger for 4 hrs. do I need to have the eignition key in the off position at the left or in the streight up and down position or all the way to the right to start? Or does this matter at all.

The switch or panel should be marked. All the way left is "off" middle is "run" right is "start"
