求翻译：3, check the Aerial magnetic relay. In turn the ignition switch, the magnetic field should make the normally open relay contacts close, and hear the "clicks" of sound. If contact can not be closed (not hear the "clicks" sound), you should check the connection guide magnetic field of the relay is open or off Victoria. If the lead-dimensional good contact, you should check whether the magnetic field of the relay contact gap is too large, contact with or without oil, ablation; then check the relay-dimensional magnetic ring is burned, open circuit or short circuit; check the contact spring can not wear contacts are leaving the contact.是什么意思？
