SPEEDOMETER INSPECTION
If the speedometer, odometer or tripmeter does not function prop-
erly, inspect the speed sensor and the coupler connections. If the
speed sensor and coupler connections are OK, replace the com-
bination meter with a new one.
SPEED SENSOR INSPECTION
• Remove the frame side cover (left side). (!5-6)
• Disconnect the speed sensor coupler.
• Remove the speed sensor 1.
• Connect a 12 V battery (between B and B/W), 10 kΩ resistor
(Between B/R and B) and pocket tester (tester + probe to B
and tester - probe to B/R) as shown.
B/R : Black with Red tracer
B/W: Black with White tracer
B : Black
# 09900-25008: Multi circuit tester set
' Tester knob indication: Voltage (&
• Move a screwdriver back and forth across the pick-up surface
of the speed sensor. The voltage readings should cycle as fol-
lows (0 V → 12 V or 12 V → 0 V). If the voltage reading does not
change, replace the speed sensor with a new one.
NOTE:
While testing, the highest voltage reading should be the same as
the battery voltage (12 V).
OIL PRESSURE INDICATOR INSPECTION
• Remove the signal generator cover. (!3-13)
• Disconnect the oil pressure Green/Yellow lead wire from the oil
pressure switch.
• Turn the ignition switch to the "ON" position.
• Check if the oil pressure indicator lights up when grounding the
Green/Yellow lead wire.
If the oil pressure indicator does not light up, check the couplers.
If all of the connections are OK, replace the oil pressure indicator
with a new one.
• After checking the oil pressure indicator light, install the signal
generator cover. (!3-48)
