I own a 200l Mustang 3.8 convertible and have what may be an excess parasitic battery drain attributable to the circuit served by the 5 amp fuse located in fuse slot 39 of the under-dash fuse box. In the Owner’s Manual this fuse is listed as servicing a “GEM”, which I understand is Ford’s acronym for “generic electronic module”. Does anyone know what device or process is controlled by this particular “generic electronic module” , where this module is physically located within the car, and whether a parasitic battery drain of 80 milliamps would be excessive or within limits for this module?
