3-13. Storage Batteries, Cables, and Terminals (fig.

Fig. 3-10)

a. Inspection. Inspect batteries for leaks, corrosion,

proper electrolyte level, and breaks or cracks. Inspect

cables and terminals for corrosion and for broken cables

or terminals.

b Servicing and Testing.

(1) Clean batteries and terminals with a solution

of water and baking soda and wipe dry.

Keep batteries filled to proper level with electrolyte.

(2) Test the specific gravity of each cell with a

hydrometer. If the specific gravity reading is below 1.225

on the hydrometer, charge the battery. Specific gravity

readings of 1.260-to1.270 on the hydrometer indicate a

fully charged battery.

c. Removal.

(1) Disconnect and remove the negative lead,

then disconnect and remove the positive lead at the

battery.

(2) Remove battery.

d. Installation. Reverse procedure in c above, using

a fully-charged battery.

3-14. Hydraulic Steering System Filter

Observe the filter condition indicator (fig. 230) daily. The

filter element must be changed when the needle moves

into the red danger zone. If filter requires changing,

report to higher authority.
