1987 NISSAN PULSAR fuse

216 Electrical System

NOTE: While checking the operation of the
fusible link, loosely connect the battery-
terminal only, to safeguard against damage
to the wiring harness.

(5) If the circuit is still inoperative or the fusible
link burns out again, refer the problem to an auto-
motive electrician.

RELAY LOCATIONS
The various relays employed in the vehicle elec-
trical system are located behind the fusible links
adjacent to the washer bottle in the engine compart-
ment, on the engine compartment bulkhead, under
the windscreen wiper motor and in the fuse box at the
lower right hand side of the dashboard.

The engine compartment relays power the radia-
tor fan, horn, condenser fan, bulb check, automatic
transaxle neutral safety switch, air conditioner and
condenser motor.


Installed view of the fuse box relays.
The fuse box relays power the fuel pump, ignition,
some accessories and the el ectronic control module.

18. TRAILER WIRING
There are several brands of trailer wiring connec-
tors available with a variet y of pin configurations. The
most common is the seven pin type which provides
for two auxiliary circuits, usually used for reverse
lamps and electric trailer brakes.
