TWIN COMANCHE C/R
Electrical switches for the various systems are located primarily in the lower left sub-panel. Rheostat
II
switches control the interior lighting: the instrument post light switch is on the left sub-panel just below the
parking brake handle. the map light switch is just to the right of the brake handle and the switch for back
lighting of the radio selector panel is centrally located at the top of the radio stack. The instrument panel
II
can be illuminated from the cabin ceiling by turning the switch in the. center of the overhead light panel.
The alternator shunt fuses and spare fuses are located under the floor panel access door aft of the nose
wheel well. The circuit breakers are located on the lower right sub-panel and automatically break the I
electrical circuit if an overload occurs. It may be necessary to allow approximately two minutes for the
7
circuit breakers to cool before resetting them if an overload occurs. Corrective action should be taken in
event of continual circuit breaker popping. It is possible to trip the breaker manually by pulling out the
reset button. Do not open alternator switches in flight unless an emergency arises. If power loss occurs,
I
reduce electrical load to a minimum and terminate flight as soon as practical.
