NOTE: Solenoid coil resistance should be measured
with solenoidat approximately 68
o
F(20
o
C). Resistance
may be slightly different than listed at different tempera-
tures. Typically, a failed solenoid coil will either be
shorted (very low or no resistance) or open (infinite re-
sistance).
4. Using a multimeter (ohms setting), measure resis-
tance between the two (2) connector terminals on the
solenoid valve coil. The resistance for the solenoid coils
is identified below:
Solenoid Valve Coil
Resistance
S1, S3 and S4 (lift) 8.8 ohms
S2 (lift) 7.1 ohms
Leak Detector 7.2 ohms
5. If solenoid coil resistance is incorrect, replace sole-
noid (refer to appropriate control manifold service pro-
cedures in the Service and Repairs section of Chapter
5 -- Hydraulic System).
NOTE: The lift manifold S1, S3 and S4 coils are identi-
cal. To assistin troubleshooting,identical solenoid valve
coils can be exchanged. If the problem follows the ex-
changed coil, an electrical problem likely exists with the
coil. If the problem remains unchanged, something oth-
er than the solenoid coil is the problem source (e.g.
switch, circuit wiring, hydraulic problem).
6. After c oil testing is completed, connect wire harness
electrical connector to the solenoid valve coil.
7. Secure all machine components that were removed
to access hydraulic manifold.
