2 STROKE OIL RESERVE WARNING LIGHT<br />
The 2 stroke oil reserve warning light comes on every<br />
time the engine is started, to make sure that the bulb<br />
functions correctly.<br />
TROUBLESHOOTING<br />
A. WARNING LIGHT DOESN’T COME ON WHEN OIL<br />
LEVEL IS INSUFFICIENT<br />
– Check the bulb.<br />
– Make sure that there is voltage on the green/red cable<br />
of the 2 stroke oil level sensor.<br />
– Check the cable connections.<br />
– Check the 2 stroke oil level sensor.<br />
B. WARNING LIGHT REMAINS ON EVEN IF OIL<br />
LEVEL IS SUFFICIENT<br />
– Check the cable connections.<br />
– Check the 2 stroke oil level sensor.<br />
CONTROL DATA<br />
CHECKING THE 2 STROKE OIL LEVEL SENSOR<br />
– Disconnect the cables which connect it to the system<br />
and remove it from the tank.<br />
– Using the ohmmeter function of the multimeter, attach<br />
the multimeter leads to the sensor cables.<br />
– When the sensor is in the vertical position, it should<br />
show a short circuit, that is, less than 0.1 Ω.<br />
– In the reverse position, it should show an open, that is,<br />
infinite resistance.<br />
CONTROL DIODE<br />
– Disconnect it from the system.<br />
– Using the diode testing function of the multimeter,<br />
connect it as shown in the figure.<br />
Correct value (measure A): 0 - 1<br />
Correct value (measure B): ∞<br />
If the tester does not include the diode test function, use<br />
a 12V battery and a 12V - 2W bulb, connecting the diode<br />
as indicated in the figure.<br />
WARNING<br />
Do not use bulbs over 2W, since the diode may be<br />
damaged.<br />
Test (C): the bulb does not light up.<br />
Test (D): the bulb lights up.<br />
