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-, or 80-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).
