Dodge Magnum Relay
The Dodge Magnum Relay is an electrical switch that allows little control signals to switch on large A/C parts to maintain steady cabin temperature. The Relay drives the fan motor, blower motor, and compressor clutch by opening or closing contacts fed by low current, not by sending heavy draw through dashboard controls. Due to a bad Relay, the blower can go dead, and modern Dodge owners benefit. Some of the early models of the Magnum applied electromechanical versions. These relied on an electromagnet to pull the contacts together. It gave reliable service but did make a faint click on each cycle. The Magnum editions that came out later switched to solid state designs that do exactly the same with semiconductor circuits, eliminating moving parts for faster response and longer life. This upgrade enables Dodge electronics to run cooler. For energy retention after shutdown, magnetic latching styles are available in some Magnum climate setups, keeping the circuit in its chosen state until a reverse pulse arrives. By testing the Relay before changing out large components, the shop saves time and money, and each Relay ensures there won't be any costly comfort failures in every Dodge cabin.

Dodge Magnum Relay Parts Questions & Experts Answers
- Q: How to test and replace a faulty relay in a Dodge Magnum?A:Relays transmit current from the component to many electrical accessories in a vehicle. Damaged relays hinder efficient operations of components. While most relays are in the engine compartment fuse and relay box, some are located elsewhere on the vehicle or in various wiring harnesses beneath the instrument panel. A suspected faulty relay can be removed and checked. These vehicles mostly use a type of relay referred to as "ISO" relays which stand for International Standards Organization. The ISO relays have numbered terminals which show their normal circuit connections and functions. There are two basic terminal layouts used on the relays in these vehicles. Two of these terminals connect to the control circuit of the relay and are connected to the coil, while other terminals go to the power circuit. Terminal 86 takes battery positive (B+) voltage, while terminal 85 is ground if diode equipped, and normally this is control circuit. The battery voltage (B+) source for this particular circuit loads is connected through terminal 30 while terminal 87 goes to the ground side of this same circuit. In order to test continuity through control coil, an ohmmeter should be utilized; resistance in proper directions has also got to be checked when a resistor or diode is present within that relay. To do this, remove it from its position in the vehicle and try checking continuity between its power circuit terminals. If tested with a relay de-energized, there should be no continuity between terminal 30 and 87. Connect one end of a jumper wire to terminal 86 and positive battery terminal; then connect another jumper wire between terminal 85 and ground such that when all connections are made together, the relay will click. With jumper wires connected check continuity again at these power circuit terminals if any tests fail replace that relay with a good one.
