9-32 ELECTRICAL SYSTEM
• Connect 12 V battery (between O/R and B/W), 10 kΩ resistor
(between O/R and P) and the multi circuit tester (+ probe of
tester to O/R and - to P) as shown right illustration.
O/R : Orange with Red tracer
B/W : Black with White tracer
P : Pink
 09900-25008: Multi circuit tester set
 Tester knob indication: Voltage ()
Under above condition, by rotating the drive lugs of speed sen-
sor slowly, the tester reading voltage relatively changes (0 V →
12 V or 12 V → 0 V). If the tester reading voltage does not
change, replace the speed sensor with a new one.
NOTE:
The highest tester reading voltage (12 V) while testing is same
as battery voltage.
OIL PRESSURE INDICATOR
NOTE:
Before inspecting the oil pressure switch, check if the engine oil
level is correct. (2-11)
• Disconnect the oil pressure switch lead wire from the oil pres-
sure switch.
• Turn the ignition switch ON.
• Check if the oil pressure indicator A will light and LCD B will
flicker, when grounding the lead wire.
If any indications are abnormal, replace the speedometer with a
new one after checking connection of couplers.
