7 - ELECTRICAL SYSTEM
Electrical energy is supplied by a 12-volt direct-current system. Energy is sup-
plied 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 elec-
trolyte at correct level. Battery elements must be completely submerged.
Before installing battery, accurately clean support removing any trace of electro-
lyte 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 regula-
tor with integrated rectifier. Generator servicing and repair must be carried out
by specialized personnel.
Circuit protection is through fuses located on right lower side of dashboard. The
drawing below shows position and capacity of fuses used.
