You simply dial the proper function and scale touch the two test leads to the wiring or device in question and check the meter reading. Find the two connections where wires connect to your part. Even if you don t have an electrical schematic of the circuit board which would identify components and give you the voltage and resistor values that should be present many circuit boards have test points that are clearly labeled. Use a multimeter on these test points to see if the voltage measured matches the labeled test point voltage. Using your multimeter you can determine if a bulb has blown or a fuse is bad or ensure that any other number of components has good electrical connectivity.
