The FAASV Automatic Fire Extinguishing System (AFES) Troubleshooting Aid is a test box and set of seven
connecting cables, developed by HTL, to assist the FAASV user in troubleshooting the FAASV AFES. Using
the troubleshooting aid allows testing of both the crew and engine subsystems individually without the fear of
accidental discharge of fire extinguishers. This is accomplished by disconnecting the FAASV's installed fire
extinguishers from the AFES and substituting ‘dummy” simulation fire extinguishers contained within the test
box. Use of the troubleshooting aid speeds faultfinding and helps achieve a more accurate fault diagnosis by
allowing maintenance personnel to take measurements at the test box. The troubleshooting aid allows the user
to isolate an AFES problem without moving the projectile racks, saving considerable time and effort. The
troubleshooting aid should be used in conjunction with TM 9-2350-287-20-1 and TM 9-2350-287-20-2 as the
technical manual is used for reference in the following troubleshooting procedure.
