A relay will have a control circuit and a function circuitcould be the same feed line.
One set of terminals (Hot and Load) can be activated at all times, but will not function until the control circuit is closed.
The control circuit has a Hot and a Ground--when activated either by supply hot or ground by switch. The internal coil closes allowing the function circuit to operate.
The purpose of this relay is to reduce the spike to the alternator.
It takes less current (voltage) to close the coil on the relay than it would to operate the accessory that it controls
What else can I help you with?
How do you check the under voltage relay?
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
Can you define the term OCR in electrical terminology?
OverCurrent Recloser, or OverCurrent Relay.
What is difference between reverse power relay and directional relay in electrical protection?
A reverse power relay is a directional overcurrent relay. Directional relays are relays that sense power flow in one direction, and include (directional) overcurrent relays, reverse power, and impedance based relays. So a reverse power relay is a directional relay, but a directional relay is not necessarily a reverse power relay.
What is over load relay?
to be protect the motor and electrical equipments.some circuit provide to protect the motor.for exm.DOL starter, OLR to protect the motors....
What is an electrical switch that opens and closes under the control of another electrical circuit?
If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
Internal circuit of an electrical relay?
basic circuit of electrical protective relay
Do nerves relay messages?
Nerves relay messages by transmitting an electrical impulse.
Where can I find a electrical relay for my Berkline lift recliner?
An electrical relay for a Berkline lift recliner can be found online at Allied Electronics (www.alliedelec.com)
What is the purpose of an automotive relay?
The Purpose of a Relay is to control multiple electrical components at once.
What is work of relay?
A relay is an electrical device that opens or closes in response to a small electrical current or voltage. This makes or breaks the connection in another device.
How do I know if I have a bad Fuel pump or fuel relay?
Bypass the relay and if the pump works the relay is bad.
How do you check the under voltage relay?
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
Is the starter relay and horn relays the same?
No, the starter relay and horn relay are not the same. The starter relay is responsible for activating the starter motor to crank the engine, while the horn relay controls the electrical circuit for the horn. Each relay serves a distinct function in the vehicle's electrical system, and they are typically located in different areas of the fuse box or relay panel.
Why would nothing happen when you turn the key on a 2001 Blazer if everything electrical works?
Starter relay, neutral/park safety switch, ingition switch in the column, ignition fuse.
What does the starter relay do in Chevy Malibu?
Starter relay protects the ignition switch from excessive electrical draw.
Can the fuel pump relay be bad if pump works?
If the pump is running the relay is good.
How can you tell if a power window relay is bad on a 1974 corvette?
put in a new relay... if the window works it was a bad relay
