What role do relays play in electrical systems, and how can faulty relays be tested and replaced on Chrysler PT Cruiser?

Some of the electrical accesses in the vehicle are the fuel injection system, horns, starter and fog lamps, and relays are used in their functioning as circuits in which low current control circuit opens and closes the high current power circuit. A defective relay will stop the intended component from working correctly; most of the relays are in the engine bay fuse/relay box with a few small ones above the interior fuse box in the dashboard. If a faulty relay is thought to be present, it is removed and checked, and where required, the relay as a sub-assembly is replaced. Practically all relays installed in these cars are ISO relays that feature terminals that are numbered with reference to the circuit connections and application, and they tend to come with two types of terminal arrangements. One set of the terminal of the control circuit is connected to the relay coil, the other set being part of the power circuit; when the coil is energized it forms a magnetic circuit which closes the larger contact to allow the supply. Terminals 85 and 86 are usually used to fulfill the role of the control circuit, and particular connections may be necessary if a diode or resistor is provided. Terminal 30 is associated with the battery voltage side for circuit loads and Terminal 87 is associated with the ground side, with other terminal numbers for other connections. In order to check continuity through the relay control coil, an ohmmeter should be used with proper polarity and the resistance value should be checked and is indicates the relay status. The relay power circuit terminals should have no continuity when the circuit is de-energized, Upon connecting a fused jumper wire to terminal 86 and the positive battery terminal there should be a clicking sound from the relay. If continuity is present between terminals 30 and 87 with the relay energized it passes the test; if not the relay should be replaced.
