I wish someone had replied, because I can't seem to find it either! All you have to do is find the battery and the game will do the rest.
ok, I editted this as I found the batteries:
fortune teller - lower left of picture on the chair
junk yard - lower right of picture, I think on the bumper
Rocco's News - right window, lower right corner
Sewer - lower left next to the black and yellow stripe.
Merry Go Round - lower right, on top of the fence post cap
Gas station - left side just below the center
Pier - next to the time clock, under the life ring
