Horn circuit check
-Check that battery voltage is normal.
-Set the multimeter to the 20Y DC range, and connect
the meter to the leads that were disconnected from the
The + meter lead goes to the brown lead

-Disconnect the leads to the horn
and connect a multi

range to the horn terminals to
check for continuity (close to zero ohms)
reading is several ohms or if there is no reading at all,
replace the horn
A. Check the resistance across the horn terminals.
WATER TEMPERATURE GAUGE
Both the fuel and water temperature gauges are
As shown in the diagram, two
gauges are powered by the battery through the 7-volt
Each gauge is of the bimetal type,
and the indicator needle swings according to the amount
of current flowing through the gauge. The amount of
current is controlled by the fuel level sender and the
Fuel Gauge and Water Temperature
Fuel Level Gauge
Level gauge circuit check
-Remove the fuel tank (Pg. 46).
-Disconnect the 2-pin connector to the
on the ignition switch
At this time the g<luge should
-Short-circuit together the black/yellow and
yellow leads on the gauge side of the 2-pin
At this time the gauge should read
