The battery equalizer is located on the left rear wall of the
cab. The primary function of the battery equalizer is to
maintain battery balance or equalization charge in a
predominately 24-volt system which requires regulated
12-volt power. The battery equalizer can deliver up to
100 amps of continuous 12-volt current for practically any
12-volt or 24-volt load such as two way radios, navigations
or the 24-volt batteries.
