12.Start switch
• Check the start switch for continuity.
Refer to "CHECKING THE SWITCHES".
• Is the start switch OK?
YES
13.Decompression solenoid
• Disconnect the decompression solenoid
couplers from the wire harness.
• Connect the pocket tester (Ω × 10) to the
decompression solenoid
shown.
Positive tester probe → green 1
Negative tester probe → green 2
• Measure the decompression solenoid
resistance.
Decompression solenoid
resistance (thermistor)
70 Ω at 25 °C (77 °F)
NOTE:
_
The resistance value for the thermistor
changes when the temperature changes;
therefore, measure the decompression sole-
noid resistance at the specified temperature.
• Connect the pocket tester (Ω × 1) to the
decompression solenoid
shown.
Positive tester prove → black 3
Negative tester probe → black 4
