I measure it as 0.33amps with everything switched off and doors closed|||I'm not familiar with your particular vehicle but as a general statement I would expect it to be lower than that.|||it depends on what the radio and alarm system needs.|||the old industry standard [still true] is no more than 31/2 volts draw. the new industry standard is 400 milleamps max.regaurdless of voltage read [this allows digital multi-meters to be used, as they will show a draw of 12 volts even at 0.005 amp draw] [move the decimal over on your reading. you have 330 milleamps this is allowable] if battery keeps going dead and charging system is ok .. i would suspect a bad battery, [did it pass load test [1/2 of cold cranking amps for 15 seconds ?]. [a good battery will not drop below 10-1/2 volts during this test. cheap parts store batteries may have trouble maintaining 9-1/2 volts during test, but anything below 9-1/4 volts should be re-charged,allowed to cool down and be re-tested if it fails again replace it.
good luck|||get the new battery
