Gun Service
The subsections that follow describe steps for testing and replacing the gun components.
The gun body contains micro switches for the trigger, grenade button, and flamethrower button,
and a coil and plunger assembly that creates the force-feedback recoil effect when the gun is
fired. To service these parts, you need to open the gun case. See Figure 23 for a view of the
open gun assembly.
The base of the gun contains pots that relay the gun position to the computer. If the gun position
is not being read properly, refer to the gun pot service steps on page 27. You
do not
need to
open the gun case to test or replace the pots.
Important:
If the guns are connected to the PCI USB ports, connect them according to the label
above the ports. The ports used may vary depending on the brand of PCI USB card used. Guns
can also be connected to the motherboard USB ports. See Figure 38 on page 53 for more
information.
Gun Power Harness Fuses
The gun power harness has two fuses, one for each gun. If a gun has no power, check the fuse
and replace if necessary. Spare fuses are taped to the harness near the fuse holder. Replace with
MDL 2A Slo Blo fuses.
