h. Battery Installation.
(1) Place the storage batteries (7, fig. 31) in the battery box (18). Make sure that common terminals are in the
same side; the positive (+) terminals should be nearest the fuel tank.
(2) If removed, cement two battery clamp pads (1) to each battery hold-down clamp (2). Mount the clamps with
four hex nuts (3) and lockwashers (4). It may be necessary to adjust the position of the hex nuts (3) under
the clamp to provide positive holding.
(3) Connect the electrical lead assemblies (5, 6, and 20) to the batteries as shown in figure 30.
(4) Install the hood sides (par. 130).
91. Current and Voltage Regulator
a. Removal (fig. 32).
(1) Remove the three regulator terminal screws and disconnect the electrical leads (28 and 29) from the
regulator terminals. Tape together and mark each group of wires so that they can be reinstalled easily.
(2) Remove the ground screw (6) and lockwasher (5) that attach the bond strap (4) to the regulator cover.
(3) Remove the three hex nuts (2), lockwashers (3) and mounting screws (11) that fasten the regulator to the
regulator support (10), and lift off the regulator (1).
b. Installation (fig. 32).
(1) Position the regulator (1) on the regulator support (10) and install the three mounting screws (11),
lockwashers
(3) and hex nuts (2).
(2) Attach the bond strap (4) to the regulator cover with the ground screw (6) and lockwasher (5).
(3) Attach the electrical leads (28 and 29) to the regulator terminals with the terminal screws.
Note. Momentarily connect a jumper lead between the BATTERY and GENERATOR terminals of
the regulator before starting the engine-compressor. This produces a momentary surge of current
from batteries to generator, thus polarizing the generator with respect to the batteries.
92. Generator and Drive Belt
a. Generator Belt Tension Adjustment (fig. 32). Check the tension of the generator drive belt by pressing against the
belt with the thumb at a point midway between the generator pulley and crankshaft pulley. It should be possible to
depress the belt approximately 1/2 inch without too much effort. To adjust belt ten-
