Psych0matt Posted December 11, 2010 Report Share Posted December 11, 2010 So, my cd player that I had in the Blazer I finally decided to put into the sedan so I can plug my phone into it. Keep in mind I threw it in the GTP temporarily for kicks, and in both it worked perfectly (like it should). I put it into the sedan with the same wiring harness, and it just kinda flickered a few lights, and wouldnt power on. I kinda shoved it back in a little and it worked. Moved it again and it didn't. I figured out that when the antenna end was touching the housing it would work. I wasn't going to plug in the antenna because I don't listen to the radio, but I plugged it in and viola! It now works perfectly. I guess I just don't get why it would do this short of having a bad ground, but the factory deck worked perfectly Also, the GTP was being screwy with the new one, but I think that's to do with the wiring harness before I fixed some crappy connections.

slick Posted December 12, 2010 Report Share Posted December 12, 2010 Bad ground. Deck was grounding through the chassis and screws. I'm willing to bet your dash kit is plastic. Quote Link to comment Share on other sites More sharing options...
alec_b Posted December 19, 2010 Report Share Posted December 19, 2010 Yup it was grounding through the antenna. Happened to me in my Aurora once, I put in a new stereo (factory one worked fine) and it wouldn't power up without the antenna plugged in. An installer friend of mine said that's pretty common actually. Quote Link to comment Share on other sites More sharing options...
GP1138 Posted December 23, 2010 Report Share Posted December 23, 2010 I almost always run the ground wire to something on the chassis, rather than using the built-in ground on the plug. Quote Link to comment Share on other sites More sharing options...

Well on the GTP I'm going to anyways. I started her up tonight just to let her run and was playing with the stereo in there, and theres a lot of hum, mostly from which I'm assuming is a bad ground.
