INTRODUCTION
One of the essential elements of an effective unit is the ability to
effectively repair malfunctioning equipment and return it to service
quickly. For the fire control systems repairer (MOS 45G), this often
means the adjustment, replacement, or repair of the electrical and
electronic components within the fire control instruments and their
associated test equipment. In order for the technician to understand
the operation of the equipment and the procedures for troubleshooting
and repair, he must be able to identify components and understand how
they function within that particular circuit.
He must also be able
to trace signals through and between circuits.
This lesson identifies typical symbols used in Army technical manuals
for electrical and electronic systems. It describes their functional
operation in circuit application.
It also provides an exercise in
wire tracing, using the procedures specified by TM 9-5855-267-24.
