7 Electrical system
Electrical energy is supplied by a 12-volt direct-current system. Energy is supplied by an engine-driven
generator and by a buffer battery.
The 18 Ah capacity battery, is located in a distinct compartment on the right side of the tail cone. The
compartment is suitably drained and vented, and access is through a small hatch secured by a screw.
Every 50 hours, or more often during summer, add distilled water to keep electrolyte at correct level. Battery
elements must be completely submerged.
Before installing battery, accurately clean support removing any trace of electrolyte and insure that drain tube is
free from obstructions. Use sodium bicarbonate solution for cleaning purposes.
Make sure battery terminals are in proper condition and apply Vaseline. Insure Master switch is OFF before
connecting cables. Also insure that no sulfuric acid comes into contact with the aircraft
‟
s structure. In case this
should occur, rinse accurately using soap and water.
Generator is permanent magnet type. DC conversion is via an electronic regulator with integrated rectifier.
