* Checking table for digital circuit tester.
NOTE 1 : Because of the difference of measuring method between the analogue circuit tester and the
digital circuit tester, polarity of tester needles should be reversed.
NOTE 2 : ”Continuity” means forward direction characteristics of the diode, and different from short
circuit condition (in which a pointer of the tester goes out of its normal scale), shows resistance
to some extent. When results of the checking indicates failure even in one section, replace
with a new one.
NOTE 3 : Simpson brand analogue testers have the characteristics as same as the digital circuit tester.
9-8 OIL SENSOR
(1) Disconnect two (2) wires comming from the
sensor at the connection.
(2) Loosen the sensor to remove it from the en-
gine.
(3) Plug the opening of oil filler hole (created after
sensor is removed) with suitable means such
as oil gauge.
(4) Connect the removed wires again with the oil
sensor.
(5) Start the engine with the oil sensor removed
and confirm if ;
a. Engine stops after 5 seconds which is normal, or
b. Engine does not stop after more than 10 seconds which is unusual.
NOTE : The sensor will not operate properly when wire is broken or poorly connected. Check the wires
for correct connection. If it fails to stop within 5 seconds after the wirings have checked, the
sensor is wrong. Replace the sensor with new one.
