100 series LC, battery is dead after 4 days. (1 Viewer)

[hold over]

Battery is dead after 4 days (new battery). There is a humming sound under the hood (not in the cab), sounds like a motor running. Only stops when the battery cable is disconnected. Ignition off, key out, Still hums. The sound comes from around the rear of the engine, perhaps from under the cover. I removed the cover and found nothing. I'm stumped.

Check around the right front fender near the windshield. There's a motor for the antenna inside the fender. I had an antenna switch on the dash that got stuck and wouldn't turn off. It tried to kill my battery.
