Questions with Automotive Relays

  • Ask: What does a relay do?

    Answer: Automotive relays are the common type of electromechanical relay that are used in all types of vehicles, like car, trucks, vans and trailers. They enable a small current flow circuit to control and operate a higher current circuit in vehicular applications.


  • Ask: What are the symptoms of a bad relay?

    Answer: Relays are often used in circuits to reduce the current that flows through the primary control switch. A relatively low amperage switch, timer, or sensor can be used to turn a much higher capacity relay on and off. Another primary use for relays is when upgrading to halogen headlights on an older car.

  • Ask: How do you wire an automotive relay?

    Answer: Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized.

  • Ask: How does a 5 pin automotive relay work?

    Answer: 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. They have both normally open and normally closed connection pins. When the coil is activated, power will be switched from the normally closed pin to the normally open pin.
