Hello My name is ***** ***** I can assist you. A parasitic draw is measured in milliamps or if very large amps. You cant measure volts. Does your multimeter have the capabilities of hooking up an inductive amp probe? If not you can put it on amps and inline with one of the battery cables but if the parasitic draw is too big it will burn your fuse.
