Examination
1. To check the supply voltage, you need to disconnect the switch block (indicated by the arrow).
2. Connect the voltmeter to the middle contact of the connector and to the "ground". Turn on the ignition and measure the voltage. It should be 12 V. If the voltage differs from the specified, check the wiring.
3. To check the idle mode switch, connect an ohmmeter to contacts "1" and "2" of the socket. The ohmmeter should show zero. This means that the contacts are closed.
4. Then turn the throttle so that the switch turns off. The ohmmeter should show infinity. Otherwise, you need to adjust the position of the switch. If this does not help, replace the switch.
5. The full throttle switch is checked in the same way, but the ohmmeter is connected to contacts "2" and "3". It shows infinity. When the throttle is turned all the way, the ohmmeter should show zero.
6. You can check the wiring by connecting an ohmmeter to contacts "1" and "20", and then "3" and "26". In both cases, the ohmmeter should show zero. Otherwise, there is a break in the wiring.
