DisassemblyNJSC0021REAR COVERNJSC0021S01CAUTION:
Rear cover may be hard to remove because a ring is used to
lock outer race of rear bearing. To facilitate removal of rear
cover, heat just bearing box section with a 200W soldering
iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARINGNJSC0021S02CAUTION:
+Do not reuse rear bearing after removal. Replace with a
new one.
+Do not lubricate rear bearing outer race.

InspectionNJEL0007FUSENJEL0007S01+If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
+Use fuse of specified rating. Never use fuse of more than
specified rating.
+Do not partially install fuse; always insert it into fuse
holder properly.
+Remove fuse for ªELECTRICAL PARTS (BAT)º if vehicle is
not used for a long period of time.

FUSIBLE LINKNJEL0007S02A melted fusible link can be detected either by visual inspection or
by feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
+If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of
problem.
+Never wrap outside of fusible link with vinyl tape. Impor-
tant: Never let fusible link touch any other wiring harness,
vinyl or rubber parts.

CIRCUIT BREAKERNJEL0007S03For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
SEL109W
CIRCUIT BREAKER (PTC THERMISTOR TYPE)NJEL0007S04The PTC thermister generates heat in response to current flow. The
temperature (and resistance) of the thermister element varies with
current flow. Excessive current flow will cause the element's tem-
perature to rise. When the temperature reaches a specified level,
the electrical resistance will rise sharply to control the circuit cur-
rent.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.

WATER TEMPERATURE GAUGENJEL0442S04The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable
ground is supplied to terminal 20 of the combination meter for the water temperature gauge. The needle on
the gauge moves from ªCº to ªHº.
TACHOMETERNJEL0442S05The tachometer indicates engine speed in revolutions per minute (rpm).
The tachometer is regulated by a signal
+from terminal 32 (Gasoline engine models) or 439 (Diesel engine models) of the ECM
+to combination meter terminal 22 for the tachometer.
FUEL GAUGENJEL0442S06The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
+from body grounds M28 and M67
+through terminals 9 and 10 of combination meter,
+through terminal 1 of the fuel level sensor unit and
+through terminal 4 of the fuel level sensor unit
+to combination meter terminal 24 for the fuel gauge.
SPEEDOMETERNJEL0442S07The combination meter provides a voltage signal to the vehicle speed sensor for the speedometer.
The voltage is supplied
+from combination meter terminal 5 for the speedometer
+to terminal 1 of the vehicle speed sensor.
Ground is supplied
+from body grounds M28 and M67
+through terminals 10 and 11 of combination meter
+to teminal 2 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
