ELECTRICAL
The Electrical Group uses vertical bar indicators to display currents for the alternator, battery, standby
alternator or battery (optional), and voltages for the main and essential buses for 14- or 28-V systems. The
ammeter scale(s) are dependent on the installed alternator (60-, 70-, 80-, 100-A).
The Auxiliary Ammeter scale is dependent upon the type of optional standby power installed: 0 to 70 A
(alternator) or -30 to 70 A (battery).
