3. Engine stop solenoid
1) Check if dimension A for the solenoid is from 25.5 to 26.4mm. If it is not within this range, replace the solenoid.
2)
Apply a voltage of 12V to the solenoid, and then check if dimension B is from 11.5 to 14.5mm. If it is not within this
range, replace the solenoid.
(Also check that these conditions are maintained when the rod is retracted.)

4. Glow plug
Measure the continuity between the center
electrode and the body. Replace the glow plug if it
does not show the standard resistance value.
5. Thermo sensor
Connect the thermo sensor to a tester and
measure the resistance value. Replace the thermo
sensor if it does not show the standard resistance
value.
