Figure 74: Electrical Control Panel

1. CIRCUIT BREAKER PANEL. A row of circuit breakers is provided on the Circuit Breaker panel.

Each circuit is designed to pop out if it is overloaded and can be reset by pushing it back in. A master

"bump" plate covers the panel to allow the pilot to reset all of the circuit breakers with one press of

the bump plate.

2. RIGHT-HAND FLUORESCENT LIGHT RHEOSTAT. This switch controls the right fluorescent

instrument panel light. To turn the light on, first set the switch to the START position, then adjust

intensity between the ON and DIM settings. Note, the left fluorescent light is controlled by the Left-

hand Fluorescent Light rheostat located on the Radiator Air Control panel.

3. AMMETER. The Ammeter gauge indicates the amount of current being supplied by the generator.

The gauge is graduated from 0 to 150 amperes and scaled to 10 amperes. Normal maximum current

is 100 amperes and should only be used for a short period of time. Takeoff should not be performed

if a reading of over 50 amperes is present.

4. GENERATOR DISCONNECT SWITCH. The Generator Disconnect switch has two positions: ON

and OFF. When set to ON, the generator provides power to the electrical system when the speed is

above approximately 1200 RPM. When set to OFF, generator power is not provided. All electrical

equipment on the aircraft is powered by the generator, except the Remote-Indicator Compass, which

derives power from the inverter.
