Ross Posted December 4, 2013 Report Share Posted December 4, 2013 UPDATE: Replaced the GMOS-04 with the new one - Of course they changed the harnesses so i had to re-wire the entire thing. But 3 days later with all fuses intact the battery seems fine. Looks like this was in fact the issue with my truck Sending the unit back to Metra/Axxess for their feedback.

Ross Posted December 8, 2013 Report Share Posted December 8, 2013 Correct. I think my optima is bad at this point so I'm getting it tested tomorrow but so far no issues with the draw. *fingers crossed Quote Link to comment Share on other sites More sharing options...

Bigtoyz97 Posted December 18, 2013 Report Share Posted December 18, 2013 I was having the same problem. A buddy of mine who is pretty sharp on that stuff says if you put a volt meter on and test the battery you should see .20 draw or less. Anything more than that something is on. After the computer kills the current I was still getting same thing .20. So had to go through and check all the electronics I put on and found out it was the MSD box. Even though one wire goes to batt. and they have a remote wire that gets put on a switched lead. It was not working correctly. So to fix the problem I just put a relay in and problem solved. As far as the guy who had car audio..... I would relay all the amps, DSP's, EQ's...... it just makes sure that the head unit has to be on for that stuff to really draw current no matter what.

crawlinss Posted December 24, 2013 Report Share Posted December 24, 2013 i just read that a bad DIC or gauge cluster can do this. ive been having the same issues with my 03, i found two fuses, that when removed, brought the parasitic loss to within spec. i brought to a dealer (tech specified by my tool dealer) for a pcm reprogram, had him look into it, and he didnt even find anything.
