charger and related circuits as follows (see FO-1):

Start engine (paragraph 2-3). After engine reaches 95% rpm,

set DC POWER switch to ON, check DC POWER ON indicator, set

DC POWER switch to OFF, and shut down engine. If DC POWER ON

tor did not light, see malfunction 42.

Disconnect battery, lower control panel (paragraph 4-24.a).

remove battery charger access cover, and open electrical

trays access door.

Check that battery charger circuit breakers 2CB1 and 2CB2 on

upper tray are closed (pushed in).

Disconnect cable P32A6 (20, figure 4-17) from 50 amp output

terminal J3+ (21). Tape the terminal lug on the wire to

prevent shorting.

Disconnect harness connector P2 (6) from battery charger 20

amp output connector J2 (7).

NOTE

A test wire made from 18 gage wire is required for step f.

Terminate one end of wire with a female connector pin, and the

other end with a clip.

Connect an 18 gage wire between pin B of charger connector J2

and dc ground.
