Customer Question

I added a after market radio to my 2001 buick lesabre.after adding it my car who need a jump after sitting idle for over 10 hours. I replace the battery with a new one. I took the car back to another car stereo shop and the said the radio had a short in
it. well i purchase a new after market radio from them. After the car radio was installed the car ran find, after sitting idle for 12 hours it would not start. I jump the car and it started right up and would run all day with no problem. This problem did not
start until i had them to install the first radio, What can be causing this problem. The battery will drain but all i have to is just touch the jumping cabkes to my battery and the car will turn over with no problem.

HI there, I am Cam. Can I get your first name please?

My first thought is the radio is installed incorrectly and what should be an ignition feed is being draw upon as a battery feed. With that in mind, did they check out the install again? Verify wire colours and such?

Expert:  Gm Tech (Cam) replied 1 year ago.

On your system there is no ignition feed from the car so a device called a Chime module would need to be used, this would use network signals to turn the radio on like the factory system. If not then an ignition feed would need to be added. I suspect the ignition feed and battery feeds are both connected to the orange battery feed wire.

Ok, as I mentioned Robert, it sounds like its being powered up all the time and killing it. I think they are missing something in the install.

ok i will let you know when i ask them about a Chime module
Expert:  Gm Tech (Cam) replied 1 year ago.

IF not a chime module then hijack an ignition feed from the heater system or something like that.

Very strange. I am wondering then if the actions simply installing it, they may have bumped something and caused the drain in the system.
