ELECTRICAL SYSTEM 14-55
Sensors
•
Rotate the waterwheel by hand slowly.
•
Measure the output voltage of the speed sensor.
G/R (+), BK/W (–) → 0 ∼ battery voltage; twice a rotation
(Rotate it slowly.)
If the voltage does not rise from zero to battery voltage
twice a rotation, replace the sensor.
•
Measure the output voltage of the sensor at higher
speeds.
○
Rotate the waterwheel in a fair speed by air.
G/R (+), BK/W (–) → approx. 5 V
If the sensor voltage does not reach 5 volts when spun
with compressed air, replace the sensor.
Fuel Level Sensor Inspection
•
Open the front storage compartment cover.
•
Disconnect the fuel level sensor 2-pin connector.
•
Loosen the clamp, and remove the fuel level sensor out
of the fuel tank.
•
Set the hand tester (ohmmeter) to the × 1 kΩ range.
Special Tool - Hand Tester: 57001-1394
•
Connect the tester leads the W/R and BK/W leads to
check the switching operation of the float.
Meter Reading
When sensor is held upright [A]: approx. 8.03 kΩ
When sensor is held upside down [B]: approx. 0 Ω
The meter should read as specified. If it does not, replace
the fuel level sensor.
Throttle Sensor Removal/Installation
•
Refer to Throttle Sensor Removal/Installation in the Fuel
System chapter.
