lamps, and automatic-reset circuit breakers to control operation of various systems in hull.
Cluster assembly contains engine and transmission oil temperature and pressure indicators,
battery-generator indicator, fuel level indicator, fuel tank level switch, and indicator lights.
Variable resistance type transmitters in engine and transmission oil systems provide electrical
signals to drive oil temperature and pressure indicators.
Mechanically actuated rheostats
connected to fuel level circuit in fuel tanks vary electrical current to fuel tank indicator.
Powerplant warning light is actuated by temperature and pressure-sensitive switches on engine
and transmission when oil pressure falls or temperatures are beyond safe limits.
