b. Measure from fuel solenoid housing (17, Figure 2-25) to nut (18) and note measurement.
c.
Tag, disconnect, and insulate wire 113B from starter solenoid and connect negative battery cable.
d. Move generator set MASTER SWITCH to START position and observe that fuel solenoid linkage retracts.
e.
Release MASTER SWITCH to RUN position, ensure fuel solenoid linkage remains retracted, and measure
from solenoid housing (17) to nut (18) again. Difference in measurement from step b should be 1 in. (2.54 cm).
f.
Position MASTER SWITCH to OFF.
g.
Repeat test several times to ensure proper performance of solenoid.
h.
If fuel solenoid does not travel its full 1 in. (2.54 cm), the solenoid is defective and must be replaced.
