Hello, The instruction manual says the smoke on/off switch should be right there by the return rollers but it is not, the hole labeled ABC is partially obscured by the double stick tape holding the main board on and there is no switch(see first pic). How do you turn on/off the smoke? The second pic shows a wire (the wire on the left) from the main gun that popped out of the main board when I lifted the top of the tank off. I have no idea where it goes back into the board. It is a two hole cord, but the two available slots are both 4 prongs. Help! I am a newbie here...Sorry. Sorry about the pics they were taken with a cell phone.
