In both the single and dual systems, an emergency bus is provided. This
bus is controlled by a double acting emergency bus solenoid and by an
emergency bus switch. A combination volt/ammeter is provided in both
systems. presenting system voltage and/or alternator output current. The
standard electrical power system is powered by a 28 V.D.C. negative ground,
Teledyne Critten - 60 amp alternator. The optional electrical power system
adds a Ford 60 amp alternator providing alternator paralleling.
The standard single alternator feeds its positive output to the single main
power distribution bus via the shunt resistor and the 80 amp main bus
current limiter. The shunt resistor taps feed the ammeter, therefore ammeter
indications represent total system current now.
The optional electrical power system feeds its positive output to the
main power distribution bus via separate shunt resistors and 80 amp main
bus current limiters. These shunt resistors feed a single volt/amp meter
through a switching circuit, therefore meter readings represent the output
from each alternator.
