Notice that the negative side of each battery goes to the spring
contacts of the holder .
3.5 Inserting the Holder into the Railmaster™
The battery holder is designed so that it can only make contact with
the power connections inside the gun if the holder is slid into the
gun in the correct way . If you look closely at the holder you will see
that there is a positive and negative terminal on it . These need to be
inserted into the gun with the terminals located at the top as shown
in Figure 3 .5 .
