Diamondss Posted February 5, 2016 Report Share Posted February 5, 2016 So I went to start up my 03 SS the other day and the battery was dead. I tried to charge up the battery but even after an hour I couldn't get the truck to even turn over. Seemed like it didn't have enough juice even though the battery charger said 14 volts. Also, the CD player was going crazy and the speakers were making weird sounds. Anyone had this before? I haven't had time to really look into it but was looking for a direction to start, I'm thinking a bad ground somewhere? Quote Link to comment Share on other sites More sharing options...
Blue2003SS Posted February 5, 2016 Report Share Posted February 5, 2016 How old is the battery? Even though it may say 14v it depends on how much charge it will take and how much it has in it. Put it on a good charge hopefully that is all you need. A bad ground could be the cause as well or even a short. Make sure the leads are clean and tight on the battery. Check the connector ends on the wire. They do loosen up sometimes under extreme vibraitions. Look at the grounding connections themselves where they terminate. Make sure those two spots are clean and tight. I am pretty sure the small one is the front right side of the forward crossmember and the larger one is on the right motor mount. These trucks are very finicky and sensitive to loose ground wires and terminals.

1BAD2K Posted February 5, 2016 Report Share Posted February 5, 2016 Take the battery up to an auto parts store and they can probably load test it to see if it has gone bad. Quote Link to comment Share on other sites More sharing options...
jddmj Posted February 5, 2016 Report Share Posted February 5, 2016 Had a friend with a similar problem in his suburban. It ended up being his factory bose amp. Switched it, and it has worked like a charm. Quote Link to comment Share on other sites More sharing options...
Diamondss Posted February 6, 2016 Author Report Share Posted February 6, 2016 When I bought the truck back 2 years ago the battery was junk. I replaced it with a cheaper alternative and after a year it failed too. At the start of this year I put a better quality battery in thinking I had bought a bad battery but now seem to be having the same problem again. I can't imagine 2 bad batteries back to back, seems unlikely but not impossible. I was thinking it was a bad ground of something draining the battery...

EXGM Posted February 6, 2016 Report Share Posted February 6, 2016 Yeah you have something that is causing a draw. Do you have any after market add ons? If not you may have a module not going to sleep causing the drain. Quote Link to comment Share on other sites More sharing options...
Diamondss Posted February 6, 2016 Author Report Share Posted February 6, 2016 There is a Connection on the back of the stereo head unit to hook up my iPod but other than that there is nothing. If I could get the truck started would it possibly reset the module? Quote Link to comment Share on other sites More sharing options...
EXGM Posted February 7, 2016 Report Share Posted February 7, 2016 No. I wonder how the I pod interface is wired in. If they taped into a wrong wire it could be keeping modules awake. That or you have another issue. Think of a computer system and a network. If something is wired in wrong and back feeds power it "may" be your problem. Hard to diagnose electrical issues through a computer. Your going to need to get the battery charged up and then start looking for your draw. You don't have anything like a aftermarket alarm or remote start? Easiest way may be to start systematically pulling fuses to isolate the circuit with the draw then start working to find problem like a broken or worn wire etc. Quote Link to comment Share on other sites More sharing options...
Diamondss Posted February 8, 2016 Author Report Share Posted February 8, 2016 Thank you for the advice. The iPod hookup has been on the truck for probably 5 years now. Thanks and I'll let you know what it was once I find the problem Quote Link to comment Share on other sites More sharing options...
