Using Resistsnce testing method
Set multimeter to resistance checking.Resistor has no polarity. Check the resistance by connecting +ve end of multimeter to one end of resistor and -ve wire to other end. Also calculate the resistance of resistor by using color code.Compare both reading and replace resistor if the readings are different. Checking open circuited resistors If a resistor is reading a very high resistance, above its rated value, it is open. It is defective and, thus, should be replaced. Checking shorted resistors Shorted means zero resistance.If multimeter reading is zero or very low,the resistor is shorted. Another method to check short by circuit continuity test in diode mode
