Chevrolet Express Relay Parts Questions & Experts Answers
Q: How do relays function in electrical systems, and what steps should be taken to test and replace a defective relay on Chevrolet Express?
A: Quite a number of electrical accessories in the vehicle use relays to pass current to the component, and if the relay is faulty, then the specified component will not function as expected. That fuse is more often found in the engine compartment fuse and relay box, while some are found in the several wiring harnesses underneath the instrument panel. The suspected faulty relay can be readily withdrawn and checked using a certain procedure or may be referred to a dealer service department or a competent repair shop and since the relays come as assemblies or assemblies of required relays that have become faulty, they must be replaced as a whole. Many of the relays utilized in these automobiles are termed as "ISO" relays and bear numerical suffixes referring to their typical circuit connections/uses; the ISO relays essentially have two classic types of terminal arrangements. In order to find out which wires are connected in which manner, the wiring diagram for the circuit in question must be consulted, and in the absence of this information the following facts may be helpful. The two terminals on the right are for the relay control circuit and connected to the relay coil while the other two are of the power circuit. In the energised state of the coil, the larger contacts of the power circuit are closed to allow energy to flow to the circuit loads. The control circuit is usually terminals 85 and 86; if the diode is present the 86 must go to battery positive and 85 to ground if the resistor is present either end of terminal 85 or 86 can be connected. Terminal 30 is used to link the unit to the battery voltage to the circuit loads while terminal 87 connects to the ground side of circuits. Continuity checks can be done on relay control coil using an ohmmeter by placing leads on the meter in correct polarity then switch the sides of lead to check for continuity in the other direction. If a resistor is present, the resistance should be equal whether in forward or reverse polarity, if a diode is present then resistance should be higher in forward polarity. Thus if there is an infinite resistance in normal as well as in the auxiliary circuit, it call for replacement of the relay. Once the relay is removed continuity should be tested between the power circuit terminals, there should be no continuity from terminal 30 to 87 when the circuit is de-energized. If a fused jumper wire is connected to terminal 86 and the positive battery terminal and another end of the relay to pin 85 to ground the relay should click. When the jumper wires are connected, there should be continuity between terminal number 30 and 87. Where any of the above tests fail, the relay should be replaced.
