Disconnect the connector from the load control valve.
Pic. 14.27. Wire connection «masses» to contact «BrY» load control valve connector
Connect wire «masses» to contact «BrY» (pic. 14.27). If all electrical consumers are turned off, the engine idle speed should be 950–1000 min-1. Otherwise, adjust the valve by turning the adjusting screw.
Stop the engine and remove the tachometer.
Before connecting the ohmmeter connector, measure the resistance between the valve connector pins. The resistance should be around 30 ohms.
