• With the ignition switch truned on, disconnect the two lead
wires going into the fuel level indicator switch, connect the
lead wires from the main wiring harness with a jumper lead
and check whether the fuel level indicator light is ON. If a
"LIGHT" is indicated, the circuit of fuel level indicator light
is in good condition. If the fuel level indicator light does not
light, replace the indicator bulb or repair the circuit connec-
tion. If the bulb is in good condition, the level indicator
switch may be faulty, replace the indicator switch with a new
one.
• Remove the fuel level indicator switch from the fuel tank.
• Connect 12V battery to the fuel level indicator switch and
ground through a 3.4W bulb. The bulb should light up after
several seconds if the switch is in good condition.
• When the switch is immersed in water under the above
condition, the bulb should go out. If the bulb remains lit,
replace the fuel level indicator switch.
