Cadillac 13500114 RELAY ASM,ACSRY TIME DELAY CUTOFF *GRAY

Several electrical accessories in a vehicle, such as the fuel injection system, horns, starter, and fog lamps, use relays to transmit the electrical signal to the component. Relays have a control circuit and a power circuit, with the control circuit opening and closing the power circuit. If a relay is defective, the component will not function. Most are found in the engine compartment or fuse boxes. To test, remove and check it for continuity using an ohmmeter. The terminals of ISO relays are numbered to indicate their circuit connections and functions.

A number of components in the vehicle employ the use of relays to switch electrical signals to the parts and the following are some of them, the fuel injection systems, horns, starters and the fog lamps. A relay works on the principle of switching on and off of a low current path called the control circuit to switch on and off a high current path called the power circuit. Any malfunction or failure in the relay will mean that the pertinent component will also not function as it is supposed to. Generally, relays are affixed in the engine compartment and in the interior fuse and relay boxes.

Some of the electrical accessories in the car the fuel injection system, horns, starter and fog lamps utilize relays to relay the electrical signals to the concerned part. A relay works by having a control circuit, a low current in this case, to switch on or off a power circuit which is high current. If we have a defective relay, the associated component will not operate as it is suppose to or not at all. As a rule, relays are installed in the engine compartment and in interior fuse and relay boxes.

Some of the electrical accessories found in a car include the fuel injection system horn-starter fog lamps and much more that use relays to pass electrical signals to them. Relays are devices which have a low current control circuit to switch a high current power circuit. A defective relay will cause the associated component not to work as it is supposed to work. Almost all the relays are fixed in the engine compartment fuse/relay box, but a few select relays are in the interior fuse box well above the dashboard. If a faulty relay is believed to exist, it must be removed, and tested by following some procedure or taken directly to a dealer service department or a repair shop and any faulty relay must be replaced in its entirety. In these vehicles, most relays are ISO relays; they have numbered terminals, giving information about typically used circuits and their functions, and two terminal configurations. The wiring diagram of the circuit might assist in pointing the right connections that have to be made for testing purposes. Two terminals of the relay are used in the control side of the coil while the other two terminals are found in the power side of the relay. Whenever it is energised, the coil produces a magnetic field to make the larger contacts of the power circuit close to supply power to the loads. The control circuit is usually formed by the terminals 85 and 86; if a diode is provided, the terminal 86 goes to the battery positive voltage, and the terminal 85 - to the ground, and the resistor enables the terminals 85 and 86 are interchangeable. There is also another terminal to handle the rest of battery voltage for circuit loads identified as terminal 30 while terminal 87 is to where a component that is to be energized is to be connected while the other terminals that may be 87A, 87B and so on are the backup terminals. To confirm continuity through the relay control coil there is always the use of an ohmmeter which should ideally be checked with both polarities. But if a resistor is used, the resistance should be the same in each direction of operation while a diode Normally a diode will offer higher resistance in the forward polarity direction. Coil resistance of both first and second relays to zero and infinite indicating the relays should be replaced. When the relay is unscrewed and disconnected, continuity should be found between the power circuit terminals and at the same time, there should be no continuity found between terminal 30 and 87 when the circuit power connection is disconnected. By connecting a fused jumper wire to terminal 86 and the positive battery terminal, and another jumper wire between terminal 85 and the negative terminal of the battery the relay should make a clicking sound. With these connections, it should now be possible to establish continuity between terminals '30 and '87. In the case that the relay does not pass any of these tests, it is advised that it is replaced.

Many electrical devices in the vehicle, including the fuel injection system, horns, starter as well as the fog lamps, use relays in switching circuits where a low current control circuit is used to control a high current power circuit. If there is something wrong with the relay then this will not allow the component that is connected to it to work properly; most of these relays are in the engine compartment fuse /relay box while other specialized ones are above the interior fuse box in the dashboard. If there is suspicion that the relay is bad, the faulty relay can be pulled and examined, whether a special test procedure, dealer service or a repair facility or bad relays have to be replaced in their entirety. In most of these cars, you will find ISO relays, which have numbers on their terminals to show the positions of different circuits and their roles of operation and these have two typical terminal arrangements. The one end of the control circuit is connected to the relay coil while the other ends of the terminals are incorporated in to the power circuit where the coil has the capability to develop a magnetic field which tends to clamp the larger contacts for power. Terminals 85 and 86 virtually function as the control circuit; special connection may be needed if a diode or resistor is inserted. Terminal 30 connects to the positive side of the battery voltage while terminal 87 connects to the component being energised and there are other terminals numbered for other connection points. Thus the relay can be tested using an ohmmeter, it is possible to measure the continuity through the control coil and resistance values will and the behavior will be normal depending upon the position of the resistor and diode. There should be no continuity from terminal 30 to 87 when the relay is non - energized. To test it, link a fused jumper wire to terminal 86 and the positive battery terminal, and another fused jumper wire to terminal 85 and ground: the relay should click and energise, and there should be continuity between terminals 30 and 87. However, if there is any failure that is pointed out by any of the tests then the relay should be replaced.

If the relay fails the tests, shows infinite resistance, or if any of the tests indicate a failure, the relay should be replaced. It can also be taken to a dealer service department or repair shop for evaluation.

To examine continuity through the relay control coil, follow the polarity indicated in the illustration during testing and reverse the ohmmeter leads to check continuity in the other direction. A relay with a resistor should yield consistent resistance values in both directions, while a diode should exhibit higher resistance in the forward polarity direction.

Most relays are located in the engine compartment fuse/relay box, with some specialized relays found above the interior fuse box in the dash.

Relays function by using a low-current circuit (the control circuit) to open and close a high-current circuit (the power circuit). When energized, the relay's coil generates a magnetic field that closes the larger contacts of the power circuit, supplying power to the associated component.
