clamp and wrap it with protective tape. This will prevent accidental arcing when removing the battery.
(5) Loosen the connecting cable clamp nuts (14). Remove the connecting cable (15) from the battery terminals
(5 and 11).
(6) Remove the batteries.
f. Cleaning. Wash the top of the batteries and the battery cases with a warm solution of baking soda and water. Be
extremely careful not to let any of the solution enter the batteries Inspect the battery case for cracks and leaks. Clean the
battery terminals and remove the accumulated copper sulphate from the terminals and battery cables. See that the filler
caps are in place, fitting properly, and that the vent holes in the filler caps are open. Clean the terminals and battery
cables and apply a light coat of petroleum jelly to prevent corrosion.
g. Servicing. See that the water level in the battery case is about three-eights of an inch above the plates. Use only
distilled water if available. Do not fill the battery with water containing high percentages of lime, alkali, or other minerals.
Do not add water in freezing temperatures unless the battery can be charged long enough to mix the electrolyte and
prevent the battery from freezing. Replace leaky or cracked batteries.
h. Installation (fig. 26).
(1) Position both batteries between the cross members (9) of the frame.
(2) Install the battery cable clamp (10) on the battery terminal (11) and tighten the clamp nut securely.
(3) Install the connecting cable (15) on the battery terminals (5 and 11) and tighten the clamp nuts (14)
securely.
(4) Install the ground cable (6) on the battery terminal (5) and tighten the clamp nut.
(5) Connect the ground cable (6) with the ground cable bolt (8) and tighten the mounting nut (7).
(6) Install the battery cover.
112. Battery Generator
a. Description (fig. 27). The battery charging generator supplies all of the electricity needed for the starting circuit of
the engine. The armature (7) rotates between the field coils (11) and produces voltage. Due to the rotating action of the
armature, the armature conductors cut through the magnetic field first in one direction and then in the other to produce an
alternating current in the armature conductors. A commutator (12), consisting of copper segments insulated from each
other and from the armature core and shaft, reverses the connections of each field coil (11) as the generated voltages
reverses in each revolution. This results in a direct current which is carried away by the brushes (4). The generator is
cooled
