The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
its at the top of the fuse panel under the dash. its realy at the very top 180 not 109. 109 is the load reduction relay for the ecm and cluster.
A relay is basically a controllable switch that connects a supply voltage to a load. If the relay is switch such that the load is not connected, that could be considered an open load. If it is switched the other way the load will be connected to its supply voltage. A defect in a relay would be something that caused it not to function correctly. It could be in the switch portion of the supply portion of the relay. Hence you are referring to different things and a defect may or may not cause the load to be open.
how to test over load relay in power panels
A reduction in load
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
overload relay is used only to protect motor or any connecting device from overload and glass relay is used for signaling.
Load Inc. was created in 2003.
Undervoltage protection is provided for A circuit bars,motors, generators, transformers, rectifiers, etc.. Such protection is given by means of undervoltage relay. Undervoltage relay are necessary for voltage control and reactive power control of network buses and load buses. These type of relays have inverse time characteristics and their operating time reduces twith the reduction in operating voltage.

Reduction of transient load and lightining strikes
If the relay contacts are in series with a connected load, then the load will energize.
The use of over load relays in circuits is to protect the circuit against over heating .
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.
The timer will have terminals associated with it. They may be on a relay socket that the relay plugs into. There will be two terminals used to bring the supply voltage to the relay timer. The load will be connected in series to either an open or closed set of contacts on the relay. The load voltage is controlled by the timer relay.The operation is, when the timer relay coil is energized the timing circuit in the relay is energized. This starts counting down until the time set point is reached and then the contacts either open or close depending on what set of contacts that you connected the load to.Some timer relays need to have the timer coil circuit de energized to reset the timing relay, others use a separate input voltage terminal on the relay to reset it without having to de energize the whole relay.
You need a double pole relay, that is a relay with 4 connection places. [screws, etc.]. Place your 2 hot wires on the screws marked line, makes no difference which wire on which screw. The 2 wires being energized by the relay action go on the load screws of the relay. Square D makes a good quiet relay. Also make sure you buy a relay large enough to carry the load. The amperage on the device the relay is to control will determine the relay size. See View Discussion for more information.
I think that would have to be some relay or contactor coil for a fan, compressor or relay contacts.

full motor load plus 5% -full motor load on name plate of motor
30 and 87 are the load connections. 85 and 86 are the trigger connections. 30, battery power. 87, load (component). 86, to switch that turns on the relay. 85, to ground.
according motor which we use suppose if it is 2.2kw then the range of OLR(over load relay) is 2-3.2
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.
A small light bulb is often used to test a solid state relay (SSR). That is because a SSR needs a minimum load of at least 0.1 amps in order to operate. Using a meter does not provide a sufficient load.
