joe, you use the test light in series between the negative battery terminal and the ground wire. similar to using an ammeter but if all is normal the light will be very dim almost off, if theres a draw, the light will be lit up much brighter, when the problem circuits fuse is pulled, the light goes dim or out then. its a primitive and easy meathod to check for draws but it works great and not everyone has an ammeter.
