4.6.16.3.3 Co-axial machine gun firing circuit. To determine conformance to 3.4.15.3.3, a
13 A load shall be connected at the output of the machine gun firing circuit and the voltage
across the load shall be tested for the presence of vehicle voltage as each respective firing trigger
is actuated.
4.6.16.3.4 Main gun and machine gun circuit controls. To determine conformance to
3.4.15.3.4, the commander's controls and the gunner's controls shall be checked for ability to fire
the weapons specified. Verify that the firing circuits from the commander's and gunner's
stations to the main gun are open when the loader's safety switch is in the SAFE position and
closed when in the FIRE position.
4.6.16.3.5 Searchlight power circuits. To determine conformance to 3.4.15.3.5, the
searchlight control circuits at the external connector shall be checked by inserting appropriate
switching leads at the internal control point.
4.6.16.3.6 Smoke grenade discharge circuits.
4.6.16.3.6.1 Arming. To determine conformance 3.4.15.3.6.1, operate the master battery
switch to ON, the turret power switch to ON, and the grenade system power switch to ON, and
verify the power-on (ready) lamp in the grenade power box illuminates. Operate the grenade
system power switch to OFF and verify the power-on (ready) lamp is extinguished.
4.6.16.3.6.2 Circuit voltage (complete installation). To determine conformance to
3.4.15.3.6.2, arm the circuit as specified in 4.6.16.3.6.1 and verify that the power-on (ready)
lamp is illuminated. Activate the RIGHT firing pushbutton and verify the voltage on the smoke
grenade discharger pins shown in figure 10 is as specified in 3.4.15.3.6.2. Activate the LEFT
firing pushbutton and verify that the voltage on the smoke grenade discharger pins is as
specified. Return the power-on (ready) switch to OFF and verify that voltage is not present on
any of the firing pins.
4.6.16.3.6.3 Circuit voltage (incomplete installation). When the smoke grenade dischargers
and pushbutton unit are not installed on the vehicle, the external firing circuits at the external
connector shall be checked on each vehicle by inserting appropriate switching leads at the
internal control point (see 3.4.15.3.6.2).
4.6.17 Performance. To determine conformance to 3.5, except as otherwise specified herein,
testing shall be performed on a hard flat level surface.
4.6.17.1 Durability. To determine conformance to 3.5.1, durability shall be demonstrated
when the vehicle is performing the 4000 mile operation as specified.
