(4) Disconnection of the Electrical Harness (Ref. Fig. 402/TASK 49-11-11-991-012)
(a)
Disconnect the electrical connections (50) P1 , (51) P2 and (55) P3 from the front fire-wall of the APU compartment.
(b)
Put blanking plugs on all electrical connectors.
(c)
Remove the bolts (54) from the brackets at the APU compartment front fire-wall.
NOTE : Hold the spacers (52) in position when the bolts (54) are
____
removed.
(d)
Move the clamps (53) away from the brackets and temporarily install the bolts (54) and the spacers (52).
(e)
Remove the bolt (56) and the washer (57) from the bracket (59) at the RH side of the APU compartment.
(f)
Move the clamp (58) away from the bracket (59) and temporarily install the bolt (56) and the washer (57) to the bracket (59).
(g)
Remove the bolt (61) and the nut (62) from the clamp (60) and
(63) at FWD RH tie-rod.
(h)
Move the clamp (63) away from clamp (60) and temporarily install the bolt (61) and nut (62) to the clamp (60).
(i)
Attach the electrical connectors (50) P1, (51) P2 and (55) P3 with cable ties to the APU. This prevents damage to the harness when the APU is removed.
(5) Disonnection of the Electrical Cables from the Starter Motor (Ref. Fig. 403/TASK 49-11-11-991-009)
CAUTION : MAKE MATCH MARKS ON ALL THE ELECTRICAL WIRES BEFORE YOU
_______ DISCONNECT THEM. INCORRECT CONNECTION OF WIRES WILL CAUSE DAMAGE TO EQUIPMENT.
(a)
Carefully remove the rubber cover (86) to get access to the starter motor electrical connections.
(b)
Remove the nuts (72) and (75), the washers (73) and (76) and disconnect the starter motor cables (74), (77) and (78).

(c)
Temporarly attach the nuts (72) and (75), the washers (73) and
(76) to the studs of the starter motor.
(d)
Put blanking caps on the disconnected ring terminals of the starter motor cables (74), (77) and (78).
(e)
Temporarily attach the starter cables (74), (77) and (78) to the FWD LH tie rod with cable ties. This prevents damage to the starter cables when the APU is removed.
(6) Disconnection of the Generator Cables (Ref. Fig. 403/TASK 49-11-11-991-009)
(a)
Remove the bolts (70), the washers (84) and remove the phase lead cover (71).
(b)
Remove the nuts (83), the washers (85) and the phase leads (82) from the generator.
NOTE : Make sure that the phase leads are identified correctly.
____ Identify the phase leads if necessary. The washers on the terminal studs are held captive on the lower non threaded portion of the studs. Do not remove them.
(c)
Put blanking caps on the ring terminals of the disconnected phase leads (82).
(d)
Temporarily install the nuts (83) to the terminal studs.
(e)
Temporarily attach the phase leads (82) to the FWD RH tie rod with cable-ties. This prevents damage to the phase leads when APU is removed.
(f)
Temporarily install the cover (71) with the washers (84) and the bolts (70).
NOTE : Because the electrical harness is removed together with
____ the APU. It is not necessary to disconnect the electrical connector (81) P4 from the generator.
