The ball park you are looking for is in the area of 25 milliamps. The old 240's routinely would draw less that 10, as the cars became more sophisticated we saw higher and higher parasitic load values. That number really jumped when we got to the 850's. It used to be you could back feed the system with a 9 volt battery wired into the cigarette lighter while you changed the cars battery and you would not loose radio codes or presets. When the 850 came along that went out the window as it will suck a 9 volt inside out before you can change out the battery. However if you can keep the load down to 25 milliamps or less and you do not leave the vehicle parked for weeks on end then you should be ok. Like the other reply said, take a look at your glove box light first and if that does not work then like the other guy said, start pulling your fuses one at a time and when you get to the one that drops the meter down to an acceptable level then go ahead and trouble shoot that circuit.
