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 | Fig. |
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.
