INTRODUCTION
As an Army maintenance provider, you have the responsibility of
giving the M1A1 series tank the best possible maintenance. The tank
uses a 24-volt direct current electrical system supplied by six 12-
volt batteries connected in a series-parallel arrangement. The power
distribution system has a power distribution box, hull networks box,
hull/turret slip ring assembly, and turret networks box.
As a Track Vehicle Repairer (63H20), you are responsible for
maintaining, servicing, and repairing the electrical systems of the
tank. To perform these critical tasks correctly, you must understand
and use the electrical schematics as described in this lesson.
PART A - OVERVIEW
