chart (page 3-13).
You must now locate the circuit point 2W1P4-20.
It is found in the middle of page 3-14. You will find that the WFOV
CMD travels from circuit point 2W1P4-20 to 2W1J1->D.
b. Since 2W1J1 is an external connection (see page 3-11), it is
necessary to refer to the interface diagram (page 3-4).
You will
find that J1 of the gunner's display meets with the interface cable
at 3W4P4.
c. To locate the connecting circuit point on the tank interface
cable, you use the tank interface cable chart beginning on page 3-5.
The WFOV CMD meets with 3W4P4 at 3W4P4->D (page 3-7). The WFOV CMD
signal travels from 3W4P4->D to 3W4P3-Y.
d. Since 3W4P3 connects to the head assembly at head assembly J1,
you will need to refer to the head assembly wire harness (page 3-27).
You will find that the WFOV CMD meets 1W1J1 at the circuit point
1W1J1-Y (page 3-27).
From 1W1J1-Y, the WFOV CMD signal travels to
1W1XA4-8, the terminal location of this signal.
e. The above wire tracing sequence is represented as indicated
below:
(1)
2W1P4-20.
(2)
2W1J1->D.
(3)
3W4P4->D.
(4)
3W4P3-Y.
(5)
1W1J1-Y.
(6)
1W1XA4-8.
5. In order to ensure that you understand the method of wire tracing
in the TTS, AN/VSG-2, trace the following signals as indicated. Fill
in the missing circuit point designators.
a. Trace the CMDR CABLE BITE signal from 3W1P1-3 to 4W1XA6-24.
(1) 3W1P1-3
(2)
(3)
(4)
(5)
(6) 4W1XA6-24
