Status: offline My 2002 Deville radio will kill the battery overnight. If I use the radio this happens. after a jumpstart, if I do not turn the radio on, the car will operate normally for days (until I use the radio). Does anyone have a suggestion as to whether it's the radio or maybe some associated circuitry? The local dealer agrees that the problem exists but his only suggestion is to replace the radio.

Status: offline The radio is wired thru a relay called a RAP relay( retained accessory power). This is to power the radio, windows, wipers for approx 10 min. after shutting off car and times out if you open a door. I've heard if the RAP relay sticks then there is a constant 12 volt source to draw down the battery. I doubt if the radio alone could kill a good battery.

Status: offline The radio can kill a battery, it happens to a lot of people. Someone probably found a good constant power source for the radio and it drains power when it's on. I turn off my radio and take the faceplate off everytime I turn off my car so I don't have this problem, if you do the same you probably wouldn't either.

Status: offline Thats assuming this person has an aftermarket radio and assuming it was wired incorrectly!

Status: offline Carnut, I could never find the RAP relay for the radio. I bought a radio on Ebay as a replacement and replaced the battery..twice. The first battery was bad.Replacing the radio cured the problem. I''ll never know why the radio caused such a drain as the Theft Lock radios are not repairable by normal repair shops. Thank you for the reply.
