kickass audio Posted April 1, 2011 Report Share Posted April 1, 2011 Heres how i would approach this... If your battery is "good" as the shop tested it, then try to remove some fuses from your fuse box for accessories such as the playstation, your tv's, headunit, and other add-ons that would not be there if the vehicle came off the show-room floor. Also what i would try to do is take your voltage meter and use it to test your remote voltage just to be sure that you have no voltage lingering through the line on that which can cause your amps to turn on and stay on with everything off. To do this, shut off the entire vehicle and take your multimeters positive probe and put that onto the amplifiers remote wire connection, then take the negative and touch a part of the body/chassis on the vehicle that is free from paint. It should read 0 volts or n/a or something like that depending on the meter. If this still doesnt work, verify your power, remote, and ground wires are in the amp all the way, chances are you may have one of your remote lead wires touching a positive wire in your vehicle which will cause the amps to constantly stay on. If the wires are in all the way, try to remove the remote wires from your amps and put electrical tape over them and leave the vehicle sit. See if this has any affect on your starting abilities. If this fixes the problem then you have an issue where your amps are not turning off when the vehicle is off. I would highly recommend starting with the fuse box first then work your way down the list. And just because i dont want to hear anybody bitch and moan on here, make sure you write down your settings on your radio just to make sure you dont lose any settings/presets when you pull the fuse for it. I noticed that it is an alpine and my alpine unit doesnt lose a single setting, not even the time when i pull the power for an entire day but i dont want to see you cry because you lost your settings. Let me know how this goes and if it helps or not, i can give you a few other things to check out.

Cashville Posted April 6, 2011 Author Report Share Posted April 6, 2011 The roof monitor was the problem. With the car off, you could turn the monitor on. Although it wasn't on whith the engine off, it using battery still. I had it fixed. Everything should be fixed now.. Let's wait and see. Thanks for all the help.

Cashville Posted April 13, 2011 Author Report Share Posted April 13, 2011 The same problem is still happening, so I guess it wasn't the roof monitor that was causing the battery discharge overnight... Quote Link to comment Share on other sites More sharing options...
Cashville Posted May 2, 2011 Author Report Share Posted May 2, 2011 I think I've found out what the problem was. After having talked to someone here in Portugal, who was having the same problem, he said he found out the problem came from the Onstar device. Since we don't have that here, I googled how to disconnect it (which I saw many people complaining from battery drain associated to onstar also), and I found a sheet, saying what fuse to take out. I took it out, and it's now disconnected. I've left my car off for 48h, and when I started the engine, it started just fine, usually it had a little difficult turning on the engine, due to low battery, so I think I finally found the problem. Just leaving it here, for other people who might find this topic, and have this same problem. Regards Quote Link to comment Share on other sites More sharing options...
