CHASSIS ELECTRICAL
8-5 3
If lamp does not illuminate, replace sensor. If lamp remains
illuminated, connect electrical lead and go to step 3.
3. Check for short circuit from sensor to module. If a
short is found, repair. If no short is found, replace module.
INDICATOR LAMP FLICKERS ON AND OFF
If a problem of a flickering low-coolant light is
encountered, it may be necessary to remove trapped air from
the radiator. To remove the air, perform the following steps.
1. With engine cold, remove the radiator cap.
2. Start engine and let run until it reaches normal
operating temperature (approximately 5 to 10 minutes).
C AUTI 0 N : When running the engine for longer
than 5 minutes, make certain that the choke is
open and fast idle speed is reduced to a normal idle
speed.
3. Fill the radiator with coolant until it is completely full
and install the radiator cap.
FUEL GAGE
Use the following procedure to diagnose an inoperative
fuel gage:
1.
Locate fuel gage sender wire (tan) in rear
compartment. With igntion "off', disconnect the wire. The
gage should read past "FULL" with ignition"on".
2. Use a jumper wire to short the connector to ground.
The gage should now read past "EMPTY".
3. If Steps 1 and 2 are OK, the trouble is in the fuel tank
sending unit, or the wiring connector at the tank.
4. If Steps 1 and 2 are not OK, remove the gage as shown
in On-Car Service and reconnect the wire in the rear
compartment. Then check the gage terminal connectors in
the instrument cluster. The three signals with ignition "on"
should be 12 volts, ground, and a signal. Use an ohmmeter
to check the signal. It should read somewhere between 0 and
90 ohms. If all three signals are OK, replace the gage. If not,
repair the wiring problem between the rear compartment
connector and the gage.
5.
A
variable resistance load may also be used in Steps
1 and 2.
A
load of 0 ohms should read "EMPTY", and 90
ohms should read "FULL".
ON-CAR SERVICE
SPEEDOMETER
On all series except X, the speedometer can be removed
as follows:
1. Remove upper trimplate.
2. Remove cluster lens (will require removal of knob for
clock or trip odometer).
3. Remove shift indicator pointer if necessary.
4. Remove speedometer head. It is NOT necessary to
disconnect the speedometer cable.
5. Replace by reversing above procedure.
To replace the X Series speedometer, the cluster must
be
removed, as described in Speedo Cluster Replacement.
The speedometer can
be
repaired at authorized repair
stations.
WARNING LAMPS
B, A, F and G Series
-
The lamps should be replaced
by removing the cluster and removing the socket on the back
of the cluster. On G and
AG
Series, removing the cluster will
provide access to the bulbs, which are mounted on the back
of the camer assembly.
X Series
-
The bulbs can
be
replaced by loosening the
carrier assembly and pulling forward to gain access to the rear
of the assembly, and removing the lamp socket.
H and H M Series
-
Indicator lamps can be replaced
by removing the upper trimplate, removing the cluster lens,
removing necessary instruments and/or coverplates, and
replacing the bulb.
FUEL GAGE
The fuel gage is replaced in the same manner as the
speedometer.
LOW-COOLANT INDICATOR LAMP
The lamp is replaced as shown for other indicator lamps.
The module replacement is shown in the I.P. Wire Harness
illustrations.
SPEEDOMETER CABLE
Speedometer cable connection at speedometer cluster is
of quick disconnect design. Fig. 8-77 shows detail. Fig. 8-78
shows attachment at trahsmission.
Remove and Replace
1. Remove lower
A/C
duct if equipped on A and
G
Series or lower I P trimplates (except X Series).
2.
Disconnect
speedometer
cable casing
from
speedometer head (Fig. 8-77).
3. Slide old cable out from upper end of casing or, if
broken, from both ends of casing.
4. Take short piece of speedometer cable with a tip to
fit speedometer and insert it in speedometer socket. Spin short
cable between fingers in direction that higher speed is
indicated on speedometer dial and note if there is any
tendency to bind. If binding is noted, there is trouble inside
