INSPECTION OF IDLE SWITCH
1.

NOTE:
Verify that the voltmeter is connected as follows:
Negative probe to LgB Positive probe to LgR
*4. Raise the engine speed to 2000 rpm. Slowly decrease the engine speed and take the readings of the voltmeter.
Between 1300-1200 RPM the voltmeter readings should increase from less than 1.5V to about 12V.
If the readings do not agree with the specification, turn the adjusting screw in 1/4 increments:
Clockwise if the reading is too low. Counter clockwise if the reading is too high.
