I remove the negative battery wire, put my multimeter inline with the battery and said wire, and place it on DCV 20 and see if there is a draw with all the lights and components turned off. Then start removing fuses until the draw drops?Additional Details98 ford mustang v6 3.8L manual trans
it would be rather hard with a multimeter because many components may add resistance that will potentially confuse the multimeter into thinking there is a closed circuit I would remove the negative battery wire, and install a 12 volt light bulb between the negative terminal and the negative wire. If it lights up then go through the fuses like before
I would use the meter in current mode, not voltage. Look for the DCA range. You might have to switch the positive lead to another port for testing current depending on the range. Like you said, hook the meter up in series with a battery terminal and start pulling fuses until the current draw suddenly drops. Then you know which circuit to investigate.
