An automotive relay is a device that uses a small amount of current to control a large current-drawing device. For example; using a small switch on your dashboard to run the starter motor on your car. The starter motor on your car is probably the largest draw of electricity from your battery. When you need the electricity from your battery to start your car, you have to control that flow of electricity somehow. In the early days of electricity (automotive-related), the designers used a large wire or cable to allow that high flow of energy from the battery to your starter-motor. This became very impractical because of the excessive size of the wiring and switches needed to run that motor. Also, the longer the wire needed to run that device, the more drop in current and voltage would occur. Hence, another source of starting problems could surface. As technology improved, so did the devices to control the flow of electricity. The relay was born! Inside the relay is a small electromagnetic coil which again, uses the small amount of electricity from that small ignition switch on you dashboard or steering column to close a set of electrical contacts inside the relay. These contacts close allowing the large amount of electrical current to flow from your battery to the starter motor, without having to have the large wires inside the car, avoids the unnecessary length of those wires and provides the shortest path of that high-current electrical power to flow from your fingers to the starter! This is just one example of a relay's use, you can substitute any large electrical device for the starter motor, automobiles can have dozens of electronic and electro-mechanical relays!

Can you use a 50 amp automotive relay with a 12V dc coil to control 12V ac 500 watt halogen lighting?
There are two ways to interpret this question. 1. No you can not use a 12 VDC coil on a 12 VAC source. 2. Check the voltage rating on the automotive relay. If it is approved for AC use then the relay will handle the 42 amps that the halogen lighting will draw. If the relay is not rated for AC use don't use it as the contact surfaces are not rated to handle the current.
What does EEC stand for in Automotive speak?

What to do when your blinkers stop working on your 1995 Saturn sl?
Replace the blinker relay, located on the fuse panel. Buy it at any automotive parts dealer.
What is the function of automotive relay?
An automotive relay is an electromechanical switch that controls a high-power circuit using a low-power signal. Its primary function is to enable or disable electrical devices, such as lights, fuel pumps, and starters, while protecting the vehicle's wiring from high current loads. By using a relay, the vehicle's electronic components can operate efficiently and safely without requiring heavy-duty switches. This enhances reliability and reduces the risk of overheating or electrical failures.
Where do i find AC relay for a 1993 Chevy Suburban?
The AC relay for a 1993 Chevy Suburban is typically located in the under-hood fuse and relay box. You can find this box near the battery on the driver's side of the engine compartment. Consult your owner's manual for the exact position of the AC relay within the fuse box, as it may be labeled. If you're having trouble, you can also check an automotive parts store or online for a replacement relay.
What relay switch is in the trunk of a Ford Thunderbird?
In the trunk of a Ford Thunderbird, the relay switch typically controls the trunk release mechanism or other electrical components related to the trunk. The specific type of relay can vary by model year, but it is generally a standard automotive relay that manages power distribution. For precise identification and specifications, it's best to consult the vehicle's service manual or wiring diagram for the particular model and year.
What type of relay for 12 volt?
For a 12-volt application, a common type of relay is a automotive relay, typically rated for 30 amps and designed to switch high-current loads. These relays usually have a coil voltage of 12 volts and can be activated by low-power signals. Another option is a solid-state relay for applications requiring faster switching and longer lifespan, although they may be more expensive. Always ensure the relay's specifications match your specific load requirements.
WHAT IS THE POSITIVE STUD AND NEGATIVE STUD OF A GLOW RELAY 12496472?
A typical automotive relay has numbered connections. Connection number 30 is the fused power supply to feed the load. In this case the load would be the glow plug(s). Number 87 is the load to the glow plug(s). Number 86 is the power supply that operates the relay, usually comes from an ignition or accessory switch. Number 85 provides the ground for the relay to operate.
1995 mercury tracer fuel pump relay wiring diagram?
To find the fuel pump relay wiring diagram for a 1995 Mercury Tracer, you can refer to the vehicle's service manual, which provides detailed wiring diagrams and relay locations. Typically, the fuel pump relay is located in the power distribution box under the hood. The diagram will show the connections between the relay, fuel pump, ignition switch, and other related components. Online resources and automotive forums may also have scanned diagrams available for reference.
