WHY IS MY CAR BATTERY GOING DEAD FROM HUMMING UNDER DASH ON PASSENGER SIDE?

I am trying to figure out why my car hums when I hook a battery charger up to it even when the ignition is completely off. I can charge the battery fine. The alternator is good because I can disconnect the battery when started, but when I let it set it goes dead really fast. The humming is coming from the passenger side in between the dash and under the hood. So I cant get to it. The idle sensor is also bad and was wondering if that might be causing it? Any help would be appreciated. Thank you.
ps. I hooked up to diagnostics and no codes came up?
