k3n12ock Posted July 9, 2010 Report Share Posted July 9, 2010 So I've been having voltage issues as of late. After selling my KInetik HC800, I was lent an Optima YT. Now, my voltage WAS normal, cold starting in the morning was about 14.6 then dropped to 14.1. This is NOT playing music. Now, when I cold start my car, my starting voltage is only 13.2. Even after 20 or so minutes of driving, it still sits at 13.2. Now that I don't have the YT, voltage with the car on is still at 13.2. I thought maybe my volt meter was off but my brothers' fluke DMM confirmed it's not the voltmeter and is something else. I have since resoldered all terminals, reran all power wires, checked and redid all grounds, redid my big 3, checked all fuses, went to advanced autoparts to get my battery checked (in good shape), and gotten my alternator checked (in good shape, although I think they only checked my started). In short, WTF IS WRONG WITH MY VOLTAGE!!!!!!! I can not for the life of me figure out what's wrong. Also, according to the Advanced print out, my battery is good and holding at 12.83V 05 xB - (2) EVIL 18s - (2) BC3500s - NO WALL Channel 1: http://www.youtube.com/k3n12ock Channel 2: http://www.youtube.com/MrK3n12ock2 Link to comment Share on other sites More sharing options...

k3n12ock Posted July 9, 2010 Author Report Share Posted July 9, 2010 OK, so I went out with my DMM. Battery voltage cold was 12.5. After starting the car, voltage was 14.8 at the battery. Turned on my highbeams and ac on full blast, went down to about 14.2 and stayed steady. Checked voltage at the alternator and seems to be putting out 13.6. Went to check voltage at the amp, reading is only 13.2. So basically this, I read that if an alternator isn't putting out over 14 it's bad. Is that true or could it be a bad fuse between the front battery & 0/1? put it on a charger for a while and see what happens. what car is this in? 01 Impala 05 xB - (2) EVIL 18s - (2) BC3500s - NO WALL Channel 1: http://www.youtube.com/k3n12ock Channel 2: http://www.youtube.com/MrK3n12ock2 Link to comment Share on other sites More sharing options...

kirill007 Posted July 9, 2010 Report Share Posted July 9, 2010 I think it's the alt, that is dieing. Advanced autoparts can't test alternators correctly, look at Dominic's vids. Thinking is the root of all problems... You ALWAYS get what you pay for. Link to comment Share on other sites More sharing options...

I didn't see anything about that in there... 3... open up your amp look at that thing... 4... hope you fix it. | S-10 | 4.5^3 ft | 33Hz | SAE-1000D @ 1 Ohm | 2 SA-12s | SPL: 143.7 Sealed | 153.4 Port Wars Link to comment Share on other sites More sharing options...
