11-41. BATTERY.
11-42. SERVICING BATTERY. The battery is located in the left forward portion of the nose section. It is
enclosed in a fiberglass box with a vent system and a drain. The vents allow fresh air to enter the box and
draw off fumes that may accumulate due to the charging process of the battery. The drain is clamped off
from the bottom of the fuselage and should be opened occasionally to drain any accumulation of liquid or
during cleaning of the box. The battery should be checked for fluid level but must not be filled above the
baffle plates. A hydrometer check should be performed to determine the percent of charge in the battery.
All connections must be clean and tight.
NOTE
Refer to note under paragraph 11-29 "Maintenance" when replacing
cables in battery circuit.
