The black on the battery should go to the black on the gun. If they don' match up then you motor will be trying to turn inreverse against the antireversal latch. The more resistance a DC motor has against turning he more current it sucks. Hence the fuse to protect the gun from this among other things. So basically your gun is trying to firebackwards and is being stopped, but you motor is still trying to do it, sucking more and more current (higher then normal) and draining you battery at an increased rate hence he heat build up from leaving the battery in the gun after trying to fire it. Usually the fuse would blow to protect the gun, but only if the current is over 15 A. If it is under 15 A the fuse won't blow. But under 15 A is still a hard discharge for you battery, hence the heat build up.
