OIL INDICATOR LIGHT

S Function
Pulses (travel distance signals) from the speedometer are counted and cause the oil indicator light to
come on at 1,000 km for the first time and thereafter every 3,000 km. In this way, this light indicates the
time for oil change.

S Resetting procedure
Travel distance can be reset if the reset button is held down for 2 to 5 seconds with the main switch
"ON".
1) If the "resetting" is done while the oil light is on, the oil indicator light goes off for resetting con-
firmation.
2) If the "resetting" is done while the oil light is off, the oil indicator light comes on for 1.4 seconds
for resetting confirmation.
S Failure diagnosis
1) Checking oil indicator light for breakage
This oil indicator light is kept on for 1.4 seconds immediately after the main switch is turned on,
thereby checking the bulb for breakage.
2) In case of meter pulse failure
If travel distance signals are not detected during running, the oil indicator light flashes and gives a
warning of meter signal failure.
NOTE:
This circuit may be activated if the engine is accelerated without load with the mainestand put up.
S Battery tending to discharge.
If the starting motor is run with the battery tending to discharge, the oil indicator light may come on (for
1.4 seconds), but this is noting abnormal.
In this case recharge or replace battery.
This light comes on if battery charging becomes poor, thereby causing the engine to run
as low as about 200 rpm against 600 rpm or so,
