Solenoid Valve Coils - Toro Greensmaster 3250-D 04383 Service Manual

Solenoid Valve Coils

Note: Prior to taking small resistance readings with a
digital multimeter, short the test leads together. The me-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
from from the measured value of the component you are
testing.
1. Make sure engine is off. Disconnect solenoid valve
electrical connector.
2. Apply 12VDC source directly to the solenoid. Listen
for solenoid to switch on. Remove voltage source from
solenoid.
3. Measure resistance between the two solenoid coil
connector terminals. The coil resistance for machines
with serial numbers under 260999999 is identified in
Figure 29. The coil resistance for machines with serial
numbers above 270000000 is identified in Figure 30.
4. Replace solenoid if necessary. Reconnect solenoid
valve electrical connector.
