GENERAL
Repair of gauges and sending units are limited to the
replacement of faulty components or wiring. Before
replacing a gauge that is not working make sure to
perform a voltage check at the gauge wire. If voltage
checks okay, a gauge that does not work is faulty
except for a water temperature gauge which can be
tested as described below.
NOTE
See Section 10N for the location of all instru-
ments and gauges.
WATER TEMPERATURE GAUGE TEST
(See Figure 10K-1)
Test the water temperature gauge as follows:
1. Turn ignition switch to RUN (ON).
2. Disconnect lead wire to sending unit on engine
and ground it.
•
The gauge indicator should go all the way up. If
not, gauge or wiring is defective and must be
replaced. If gauge needle does go to upper limit
but does not work during operation, sending unit
is faulty.
