torque kit update

finally got all the right parts in and got it installed, wow. i can now climb any hill i can get traction on(it will actually spin 22 inch tires). thnks for all the help and answers to my questions. however i have one more, my new alltrax controller has an led light on it, will it drain the batteries any or should i turn the cart off when not in use? i think i am in love :)
