17 The digital volt/ohm meter (DVOM) is a more accurate way to measure current, resistance, or voltage. The typical DVOM has a dial to choose the proper scale for measuring each, along with a selection of test lead ports to connect the leads to. To check for voltage, use the VDC scale, while resistance is measured on the ohm scale (Ω). You use a different lead port and scale (mA or A) for checking current draw. You also want to make sure there’s no voltage present in the circuit when checking resistance. Sure, the test light is lit in the previous caption, but what’s the amount of current passing through it? The current flow could be normal, like a memory circuit, or it could be an actual problem. Connect the DVOM in the same manner as the test light (ensure you have the test leads plugged into the proper ports on the meter!) and then read the actual amperage of the current flow, which is 3.308 amps in this case because we have the parking lights turned on.
