INSPECTION OF COMPONENTS
Fuel Heater
INSPECT FUEL HEATER
(a)
Apply
a vacuum of 285 t 50 mmHg (1 1.22 It 1.97
in.Hg, 38.0
t 6.7 kPa) or more to the vacuum switch
port.
(b)
Using an ohmmeter, measure the resistance between
terminal 1 and the switch body.
Resistance:
Approx. 0.7
L! at 20°C (68" F)
If the resistance is not as specified, replace the fuel heater
and vacuum switch assembly.
Vacuum Switch
INSPECT SWITCH CONTINUITY
Using an ohmmeter, check that there
is no continuity be-
tween terminal 1 and the switch body.
If continuity is not as specified, replace the fuel heater and
vacuum switch assembly.
INSPECT SWITCH OPERATION
(a)
Apply a vacuum of 285
r 50 mmHg (1 1.22 ? 1.97
in.Hg, 38.0
r 6.7 kPa) or more to the vacuum switch
port.
(b)
Using an ohmmeter, check that there
is continuity
between terminal 1 and the switch body.
If operation
is not as specified, replace the fuel heater and
vacuum switch assembly.
