Does the brake light come on, too? If you see the battery light and the brake light on at the same time, you need an alternator.
Mant years ago that was true. A 2004 will have larger electric loads than a 70's car. Probably more like 20 minutes of run time on battery only. And that assumes a very good battery.You wont get stranded. You would have at least an hour to drive after it dies before the engine quits is you don't use headlights or other loads.
Based on what Nissan/Infiniti did with their G35 (VQ35) engines, they were still using screw-type tensioners in those up until 2006. My '08 Nissan (Infiniti) does have a hydraulic tensioner.I thought a 2004 Nissan would have had self adjusting spring loaded tensioners on it.
I am curious why the brake light would come on at the same time.Does the brake light come on, too? If you see the battery light and the brake light on at the same time, you need an alternator.
I saw those u tube videos as well. Looks like a little bit of a pain to remove this alternator. The belt still "seems" tight.Mant years ago that was true.

I looked for some YouTube videos on replacing the belts on that vehicle. Found a 2005. The belts each have there own mechanical tensioner. And 14K miles on new belts could be enough that they have worn in, and now require a slight bit of tightening. Probably still very good belts with a lot of life left on them, but belts do wear in and require taking up slack.
I think automakers just do that to increase the odds of getting your attention. One warning light might get ignored, but two ? Hondas have done that for decades, in my experience.I am curious why the brake light would come on at the same time.
If it does it again, I will look for that.

If the vehicle was used to jump start another vehicle, AND the vehicles engine was running while the vehicle with dead battery was cranking or trying to crank, then under those conditions, the alternator of the good vehicle could have its alternator output diodes damaged when it puts out a lot of current to try to start the dead vehicle. This sometimes but rarely happens, because the starter of the dead vehicle and the dead battery of the bad vehicle, draws too much current.
When does it do it? at idle or anytime?My 2004 Nissan Sentra battery light flashes on and off occasionally.
It is very random and not very often, just blinks on for a brief moment every now and then. The volt meter is reading 14.4 volts at the terminals.
Is it possible the alternator is just staring to go bad, or should I look to diagnose something else?
I don't want to get stranded with a dead alternator...been there, done that...., but also don't want to waste money.
Worn out brushes can cause intermittant failure. Seen it a few times.Alternators usually completely fail, not intermittently like you are describing. If the vehicles Voltage can not stay high enough when the RPMs are low, it usually is that the alternator can not keep up with the demand at those low RPMs because the battery is not doing its share of the work, and even may be draining too much from the alternator.
I used to have a 2004 Altima. The flashing battery and sometimes the brake light also indicates a bad alternator. Easy fix but would not recommend anything Carquest for this.My 2004 Nissan Sentra battery light flashes on and off occasionally.
