Neutral Indicator System Inspection; Fuel Pump Side Level Sensor - Honda GL1800 Service Manual

LIGHTS/METERS/SWITCHES

FUEL PUMP SIDE LEVEL SENSOR

Remove the fuel pump assembly (page 5-60).
Measure the resistance between the fuel level sen-
sor terminals of the fuel pump connector with the
float at the top (FULL) and bottom (EMPTY)
positions.
RESISTANCE (20° C/68° F):
1.5 – 2.5Ω with the float at FULL position
28.6 – 30.6Ω with the float at EMPTY position
Install the fuel pump assembly (page 5-62).
NEUTRAL INDICATOR
SYSTEM INSPECTION
1. Shift the transmission into neutral and turn the
ignition switch to "ON."
The neutral indicator should come on.
• If the indicator comes on, the system is OK.
• If the indicator does not come on, go to
step 2.
2. Remove the combination meter (page 20-17).
Turn the ignition switch to "ON."
Measure the voltage between the Black/white
wire terminal (+) of the combination meter 20P
black connector and ground (–).
There should be battery voltage.
• If there is no battery voltage, go to step 3.
• If there is voltage, check for:
– reverse position switch (page 19-30)
– reverse shift switch (page 20-35)
– open circuit in the Black/white, Black/red
– loose or poor contact of related connectors
3. Check for continuity between the Light green
wire terminal of the combination meter 20P black
connector and ground.
There should be continuity.
• If there is continuity, replace the meter/gauge
assembly (page 20-19).
• If there is no continuity, check for:
– faulty gear position switch (page 20-38)
– faulty diode (D6) (page 19-28)
– open circuit in the Light green and Light
20-26
and Black/brown wires between the combi-
nation meter and reverse position switch
green/red wires between the combination
meter and gear position switch
