systems in M915 thru
ENGINE RUN SWITCH. Supplies 12-volt power from batteries through switch, circuit
breaker, to voltmeter.
VOLTMETER. 10- to 16-volt gage indicates voltage provided by battery pack, and
alternator.
ClRCUIT BREAKER (CB-6). Protects electrical components of volt meter circuit by
opening when load exceeds 20 amps. Automatically recycles until overload is removed.
BATTERY PACK. Comprised of four 12-volt, maintenance-free batteries. Two batteries
wired in paralIel in each set. Each set connected in series for 24-volt output. Battery
pack is used for both 1.2- and 24-volt output.
AC GENERATOR (ALTERNATOR). Generates voltage for recharging battery pack.
Has external 24-volt transformer rectifier.
