They do their job by activating electromagnets that pull the entire set of contacts to open or close circuits. Relays also enable you to perform your Mercedes-Benz 420SEL logical car functions and inputs. If your Mercedes-Benz 420SEL fails to start when you activate the ignition, and if the engine light is unable to switch "ON" and "OFF", it indicates that the main relay is broken. You can repair it, or buy a new one for a faster solution.
