Clownrock95 Posted February 9, 2016 Report Share Posted February 9, 2016 Maybe look up parasitic draw and how to test/find it it could be something that is not related to the audio stuff but while installing it you might have done something that you didn't realise (bumped/pinched a wire or something) Link to comment Share on other sites More sharing options...
CleanSierra Posted February 9, 2016 Report Share Posted February 9, 2016 7V is unrecoverable likely. You need a new battery. I doubt anything you did caused this dead battery issue. 7V is LOW LOW LOW. You've got a dead cell or two in the battery. Im not the one you want to try to troll. Just a fyi for you.

I doubt anything you did caused this dead battery issue. 7V is LOW LOW LOW. You've got a dead cell or two in the battery. Ok yeah it was at 7.3 when I went to bed. Got up this morning and it's back to 8.5!? So I jumped it and drove the truck to work, voltage held steady at 14.4 as long as I kept the rpms at 1500 or greater. At idle it never dropped below 13 once. My fear is buying a new battery on credit and it draining as well. Really can't afford to kill another battery.

afrakes Posted February 9, 2016 Author Report Share Posted February 9, 2016 How old is the battery? I would check the water level in it then put it on charge overnight. Then let it sit for a day disconnected. Then measure voltage. It should stay over 12v at rest. Double check your connections from the battery to the alt. I appreciate the advice, need to purchase a charger. This is a lead cell battery as well, not agm. And the battery is old. It expired 3 years ago, which is y it didn't surprise me that it died. What doesn't make sense to me is the timing. I checked the alt run again, everything is tight, and the run in total is only about 14" including the fuse holder/fuse. Fuse is still good as well (250a) Vehicle: 2014 GMC Sierra 2500HD WT Head Unit: Pioneer DEH- Mids/Highs: Focal Integration ISC 165’s (front) Subs/Amps: TBD Link to comment Share on other sites More sharing options...
afrakes Posted February 9, 2016 Author Report Share Posted February 9, 2016 Also, how do I check the water level in my battery? Never heard of this before.

CleanSierra Posted February 9, 2016 Report Share Posted February 9, 2016 Battery is done dude. Get another one. You won't have to worry about the new battery because it will have a free replacement warranty. So even if you managed to kill it when you got home, which you won't, they'll swap it for free. Even the Wal-Mart batteries they do this with. Then it's pro rated after that for another period of time so if you have to replace it in 3 years, they'll only make you pay partial replacement cost.

CleanSierra Posted February 9, 2016 Report Share Posted February 9, 2016 Also, how do I check the water level in my battery? Never heard of this before. Don't mess with it. The reason you're seeing 14.4V while driving is purely because of the alt. Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
afrakes Posted February 9, 2016 Author Report Share Posted February 9, 2016 Ok that's what I thought. Do u have any sort of idea why the battery discharged when the only thing that had changed to that point was an upgraded power run from batt to alt? It's just weird to me that the battery would suddenly die from upgrading a run.

Skullz Posted February 9, 2016 Report Share Posted February 9, 2016 Your putting a draw on the battery, something is syphoning the battery dead, it could be that the amp is not turning off from a stray wire into the remote wire hole or something else is drawing power, but you need to trace that down regardless of a new battery or not. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

Agreed. However right now the amp isn't installed. The run to the back isn't fused. It's dead wire. So the ONLY things that have changed is an upgraded big 3 in 1/0, and new rcas /remote turn on wire and volt meter . Volt meter has been ruled out as the cause because it doesn't draw enough power to do this to the battery, meter was on all night the other day with the car off and voltage never dipped below 12.2 I believe. so it has to be losing voltage through either my upgraded power wire to the alt, which I have checked, or somehow with my new turn on wire for the amp (again the amp isn't even installed so there's no power to be drawn there. I just don't know where to start. As clean said, a new battery will be warrantied, but if my new battery is just going to drain again anyways I need to find a solution to his issue.
