Testing.
‘Test the float switch (38) as
follows:
(1) Remove connector (10) from float
switch (38).
(2) Remove float switch (38) from day tank
(42).
(3) Connect an ohmmeter between pina C and

the bottom float is placed at its bottom position and
verify open circuit when float is placed at its top
position.
(4) Connect an ohmmeter between pins A
and B of the connector (10) and verify continuity
when the top float is placed at its bottom position and
verify open circuit when float is placed at its top posi-
t ion.
