2.16. ELECTRICAL SYSTEM

The aircraft is equipped with a 12-volt, direct-current electrical system with grounded negative
pole.
The primary source of electrical energy is provided by the engine mounted interior alternator/ge-
nerator with total power of 750 W.
The internal alternator located at the rear of the engine block will charge the battery up to 13.5
VDC.
Power is supplied to the electrical and avionics circuits through a main bus bar located behind
instrument panel, this bus bar is energized anytime the Main switch is ON.
Each system is protected by circuit breaker which is permanently on. If some circuit is overloaded,
then the circuit breaker disconnects that circuit.

Adjustment of engine control
The engine-control lever must move with a right effort. In case of effort's weakening, in flight the
lever could move ahead spontaneously and the engine's power setting would increase. In this
case, adjust the engine choke lever. Loosen the M8 nut, lock it with a proper spanner and secure;
consequently, the friction increases and the engine's control lever remain in a more appropriate
position.
