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 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.
Where is flasher relay on 1996 gmc sonoma?
The flasher relays are in the back of the glove compartment. They are behind a piece of plastic labeled "Relay Access" You will need to use a screwdriver to pry the bottom tabs of the plastic to pull it out. You will see three small black cubes. Those are your flasher relays. They are a standard-type relay that should only cost a few dollars at an automotive parts store.
How do you wire a 12 volt automotive relay?
there should be a diagram on the side of the relay with the pin numbers and some symbols. the pins that are on the coil or control side can be wired power and ground. this generally goes through a switch. the load side has a small gate looking symbol these can be wired power and ground either way and this is the side that you connect to whatever you are powering on. make sure to use a fuse on this circuit on the power lead.
