You can use the reference number assigned to a wire as another

way to make sure you have found the correct point where the

circuit continues. Look at wire harness 2W104 again and note

the reference numbers (45, 46, and 47) assigned to the wires

leading to connector P1. Now locate the find number on sheet

5 again.

Just below the find number you find the correct

reference number (45, 46, and 47).

Using the find and sheet circles, you know that wire harness

2W104 connects to the driver's master panel and this part of

the circuit you traced now provides power for other tank

circuits. However, to continue this lesson you must go back

to sheet 4, where wire harness 2W107-9 connects to J1 of the

hull networks box.

When you continue to trace the circuit from this point, it

leads to more find circles. However, note that wire harness

2W107-9 connects to wire harness 2W106-9, and the wire

reference numbers changed prior to the find circles. Use the

find circles to locate where the circuit continues on sheet 5.

On sheet 5, you see this part of the circuit goes to the

driver's instrument panel.

At this point, the circuit

provides power for the other tank circuits.

On sheet 4, look at the find circles given for connections E1

and E2 of the terminal boards. All four of the find numbers

in the circles refer you to sheet 6 (the number in the bottom

half of the find circle), with find numbers (the numbers in

the top half of the circles) 1, 2, 5, and 6.

Locate these

find numbers on sheet 6.

Sheet 6. When you locate the find numbers (1, 2, 5, and 6) on

sheet 6, you see the circuit now provides power to the starter

pilot relay circuit.

Before going any further, review this

sheet.

After reviewing this sheet, you know this sheet uses two other types

of find symbols, a circle and a square.

--

Find symbol for the same sheet. This circular find symbol

has a letter in the top half and has diagonal lines in the

bottom half. This symbol indicates the circuit continues

on the same sheet. Locate where 2W109-9 connects to J7 on

the hull networks box at one end (P3) and the other end of

the wiring harness has find symbols with the letters B, C,

and D in the top half and diagonal lines in the bottom

half.
