BATTERIES
DESCRIPTION
. Two 12-Volt batteries are connected in series, mounted in a
compartment behind the fuel tank compartment door on the
right hand front side. Battery cells may be checked and filled at
this point
IMPORTANT: Observe decal on inside of
battery compartment for proper connec-
tions.
The battery has four (4) major functions to perform on the
coach.
(1) It provides a source of current for starting the engine.
(2) It acts as a stabilizer to the voltage in the electrical
system.
(3) It can, for a limited time, furnish current when electrical
demands of the electrical equipment exceed the output of the
generator.
(4) It provides a limited source of power for connected
accessories. when the engine is not running.
In replacing batteries, ·only batteries of the same spe-
cification should be used. Refer to "Specifications" at the end
of this section.
The electrical system is negative ground, with the negative
battery terminal connected to the coach frame.
