6-8-2 CONSTRUCTION AND OPERATION
Disconnect wires coming from the sensor. The
oil sensor is composed of the float, permanent
magnet incorporated into the float and the oil
sensor.
In accordance with the oil level, the float moves
up and down.
When the oil level is upper level, the float
moves up.
When the oil level is lower level, the float
moves down.
The premanent magnet is close to the lead
switch, and the lead switch is activated by the
magnetic force.
