in reply #16 bv test is the same as stand alone test. there are only two switches that have to be bypassed, the one and only switch in the cash box area is usually mounted to the cash can door, two green wires. the second switch is mounted in the upper left hand corner of the belly door glass, it has two green wires. these are the only two switches you should be concerned with.
some casinos mounted a switch to the back wall of the cash can housing, it is a white cherry switch, usually it has no wires on it IF THE PLAYER TRACKING WIRING HAS BEEN REMOVED. this switch can be removed, it could hinder the cash box from going all the way in. when the cash box is all the way in it will interact with two plastic tabs which will pivot when touched by the cash can, when they pivot, they interact with the optics on the back of the transport unit, this is how the unit sees if the cash can is present.
so! it is the plastic fingers that you should check, see if both are there, and see if both move and pivot when you push on them, then inspect the rear of the transport unit where these fingers would obstruct the optics and see if there is anything in the way.
