Radio drains the battery in about 2 days.

[TBgonzo]

Need help folks,2003 TB,just bought it so I am learning things, with the radio fuse installed the battery drains and is dead in 2 days,with the radio fuse out,everything is fine.Next I unplugged the OE radio (UBO) and no battery drain,.Trying to be sure its the radio that is at fault before replacing it. Now today I plugged in a radio from 03 yukon that had bose,of course it lit up and said locked and didnt expect it to work . I guess I will see if it drains the battery in a few days.Any help or direction would be appreciated,

This test with the Yukon radio should confirm if your original radio is the cause of the drain. It does happen. Replacement radios should be plentiful in yards however the VIN will need to be programmed into it. You will be able to test it with key on aux but as soon as you put it to run, it will lock.
