To test the cigar lighter/power outlet receptacle,
first check for continuity to ground at the ground
circuit cavity of the cigar lighter/power outlet connec-
tor. There should be continuity. If OK, check the
operation of the accessory relay and relay circuits . If
the accessory relay and relay circuits check OK,
replace
the accessory switch bezel unit, which
includes the cigar lighter/power outlet receptacle .
ACCESSORY RELAY TEST
The accessory relay is located in a connector
mounted to the 100-way connector bracket under the
driver side of the instrument panel, near the cowl
side panel . Remove the relay from its connector to
perform the following tests :
(1) A relay in the de-energized position should
have continuity between terminals 87A and 30, and
no continuity between terminals 87 and 30 . If OK, go
to Step 2. If not OK, replace the faulty relay.
(2) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 75±5 ohms. If OK, go to Step
3 . If not OK, replace the faulty relay.
(3) Connect a battery to terminals 85 and 86 .
There should now be continuity between terminals
30 and 87, and no continuity between terminals 87A
and 30 . If OK, see the Accessory Relay Circuit Test in
this group. If not OK, replace the faulty relay .

ACCESSORY RELAY CIRCUIT TEST
(1) The relay common feed terminal cavity (30) is
connected to battery voltage and should be hot at all
times . If OK, go to Step 2 . If not OK, repair the
fused B(+) circuit to the fuse in the Power Distribu-
tion Center as required .
(2) The relay normally closed terminal (87A) is
connected to terminal 30 in the de-energized position,
but is not used for this application . Go to Step 3 .
(3) The relay normally open terminal (87) is con-
nected to the common feed terminal (30) in the ener-
gized position . This terminal supplies battery voltage
to the cigar lighter/power outlet when the relay is
energized by the ignition switch. There should be
continuity between the cavity for relay terminal 87
and the accessory relay output circuit cavity of the
cigar lighter/power outlet connector at all times. If
OK, go to Step 4 . If not OK, repair the open circuit to
the cigar lighter/power outlet connector as required .
(4) The coil battery terminal (86) is connected to
the electromagnet in the relay. The connector cavity
for this terminal should have continuity to ground at
all times . If OK, go to Step 5 . If not OK, repair the
open circuit to ground as required .
(5) The coil ground terminal (85) is connected to
the electromagnet in the relay. It receives battery
feed to energize the relay when the ignition switch is
in' the Accessory or On positions . There should be
continuity between the cavity for relay terminal 85
and the ignition switch output (acc/run) cavity of
the ignition switch connector at all times . If OK,
refer to Group 8D - Ignition Systems for diagnosis of
the ignition switch . If not OK, repair the open circuit
as required .

(1) Check the fuse in the fuseblock module . If OK,
go to Step 2 . If not OK, repair the shorted circuit or
component
as
required and replace the faulty fuse .
(2) Turn the park lamps on with the headlamp
switch . Rotate the headlamp switch knob counter-
clockwise to just before the interior lamps detent .
