PART I-DESCRIPTIVE

	   (iii)Generator control
	        (a) A three-position switch (82) on the right forward
	            console, controls the operation of the generator. The
	            switch is guarded in the ON position and is spring-
	            loaded from RESET to OFF.  The reset position is
	            used in the event of generator failure, see para.78.

	        (b) With engine r.p.m. above 45 per cent., the voltmeter
	            readings shown on the voltmeter (36) should be
	            approximately 28 volts.

	        (c) The generator power failure warning light (35) on
	            the lower left-hand side of the instrument panel
	            indicates any time the generator is inoperative
	            (except when the external power supply is plugged
	            in).  At the same time, the equipment in the third
	            column of sub-para. (ii) ceases to function.

	    (iv)Battery control and external power supply
	        (a) The three-position battery-starter switch (80) is on the
	            right forward console.  The STARTER position is
	            spring-loaded back to OFF, which is a maintained
	            position, as is the BATTERY position.  When the
	            switch is held at STARTER the starter is actuated
	            (see para. 13).  With the switch at BATTERY, the
	            battery will supply the services in the second column
	            of the table in (ii) above in the absence of any other
	            power source.  When the switch is OFF battery
	            power is supplied only to those services in column
	            one of the table.

	        (b) Two external plugs, No. 1 and No. 2, are located on
	            the port side of the fuselage.  An external power
	            supply must be connected to No. 1 to make power
	            available to all services.  If No. 2 only is connected
	            power is not supplied to the services in the third
	            column of the table in (ii).  For starting the engine,
	            external power must be applied to both No. 1 and
	            No. 2 plugs.

	    (v) Circuit-breakers and fuses
	        Most of the D.C. circuits are protected by push-to-reset
	        circuit breakers or circuit-breaker switches.  Panels
	        mounting the circuit-breakers are located on each side
	        of the cockpit (see Figs. 7 and 8 in Part VI) and in the
	        nose compartment.  Most A.C. circuits are protected by
	        fuses which are not replaceable in flight.

	    (vi)Control of A.C. supply
	        (a) The single-phase inverter supplies A.C. to the gun-
	            sight, IFF, the fuel flowmeter and the cockpit air
