Fuel Indicator Line Inspection; Resistor Line Inspection; Resistor Inspection - Honda 2003 NPS50 Ruckus Service Manual

2. Fuel Indicator Line Inspection

Ground the Blue/white wire terminal of the 6P
Black connector with a jumper wire.
Measure the voltage between the Light green (+)
and Green/white (-) wire terminals of the fuel
reserve indicator 2P connector.
Is there approx. 3V7
NO Faulty LED drive unit.
-
YES Faulty LED.
-
When the indicator always lights during a operation

1 . Resistor Line Inspection (1)

Turn the ignition switch to ON.
Measure the voltage between the Black wire ter­
minal of the resistor 2P connector and Ground.
Does the voltage exist?
NO - Open circuit in the Black wire between
the resistor 2P connector and main wire
harness.
GO TO STEP 3.
YES
-
2. Resistor Line Inspection (2)
Check the continuity of Blue/white wire between
the resistor and LED drive u nit.
Is there continuity?
NO - Open circuit in wire harness
- GO TO STEP 3.
YES

3. Resistor Inspection

Disconnect the resistor 2P connector.
Measure the resistance between the Black and
Green wire terminals of the resistor 2P connec­
tor.
STANDARD: 64 - 72 lill (20'C/68'F)
•
•
Is the resistance within the standard?
NO
Faulty resistor
-
YES
Short circuit in the Blue/white wire.
-
Faulty fuel reserve sensor.
