Apply a constant voltage of not more than 6 V to the idle speed controller by connecting the positive terminal of the power source to the terminal «1» regulator pads, «mass» source output - to output «2». At the same time, the governor throttle switch stem must fully retract.
Immediately after this, turn off the power supply.
Warning. To avoid damage to the idle speed controller, do not connect a current source with a voltage of more than 6 V to it.
Connect tester (in ohmmeter mode) to conclusions «3» and «4» idle speed control pads.
Insert probe «B» 0.5±0.1 mm thick into the gap between the throttle control lever and the governor idle switch rod. In this case, if the gap is within the specified limits, the resistance value should not change. If the gap does not match, this instrument will display open circuit resistance. In this case, adjust the gap with the screw «IN».
