M1A1 Electrical Schematics and Wiring Diagrams.
The electrical schematics used to trace the tank's electrical
circuits show only the components used in a given circuit; in
addition, the schematic shows all the components of the electrical
assembly of that circuit on the same sheet.
Because of this
arrangement, you can use these schematics for point-to-point
electrical connections. For example, the hull power distribution box
has more than four circuit breakers; however, the schematic for the
hull electrical system - power distribution and master power control
circuit schematic shows only four circuit breakers, because the
circuit shown has only four circuit breaker in it.
This lesson
traces this circuit in part C.
On the other hand, the electrical wiring diagrams used to trace the
tank's electrical circuits show all the components used in all
circuits; consequently, the components cannot be shown on the same
sheet. For this reason, you cannot use the wiring diagrams to make
point-to-point electrical connections.
For example, the wiring
diagram shows the hull power distribution box on two different sheets
(4 and 6).
Each time the wiring diagram shows the hull power
distribution box, it does not show all the components. You have to
examine both sheets of the wiring diagram to find all the components
in the hull power distribution box. This lesson traces this circuit
in part C.
This completes part A.
This lesson continues with a description of
the components of the M1A1 schematic diagrams.
PART B - IDENTIFYING COMPONENTS OF THE M1A1 SCHEMATIC DIAGRAMS
1.
Schematic Identification and Sheet Numbering.
The schematics and wiring diagrams show their title and level of
maintenance in the extreme lower right-hand corner. When a complete
wiring diagram consists of more than one sheet, the sheet number
appears there also. The sheet number tells you which sheet you have
and the total number of sheets that make up the diagram.
