2004 tsx battery not charging
Just replaced the alternator. Car would start and run just fine with a fully charged battery, but dies after about 15 -20 mins because the battery wasn't being charged. Pull the alternator and have it checked at autozone and they said it was good.
Charged the battery full and the car starts and run just fine. Just as I unplugged the battery, the engine dies right away, so that means the alternator is not providing any powers at all. Checked all cables and fuses looks good.
Replaced the under the hood fuse box, still having the same problem of no powers coming from the alternator.
I don't know what else to replace, beside the damn car now

Could still be a bad alternator. A DOA alternator is not unheard of

I've had their crappy machines pass bad alternators and batteries so I don't put much faith in them. Get a new one

I agree with thoiboi. It was many years ago, but had an alternator issue and parts store bench tested it twice and told me it was still good. Finally replaced it and problem solved.

Dont' trust the machines. If you want to be certain on the alternator, get an Ohm meter and see what your voltage goes to when you start your car. Then test with a load such as turning lights on and heater etc.
Eric the car guy has a great video on this.
I had a starter that was shot, tested it with a batter and it would run but I never seen a good working starter. Go to Autozone to get it tested and it passed. I was certain this was the issue. Replaced the started and the car runs fine now.

Exchanged the remanufactured alternator for a new one, didn't fix the problem. I check with my multimeter with engine off shows 12.6v. With engine running it's shows 12.3v to 12.4v. So the alternator is not charging the battery at all. Replaced the fuse box, nothing changes.
Also just found a sensor that is broken. Its located just to the right of the fuel rail on the top right of the head. Not sure what that sensor is. Hopefully replacing that sensor will cure the not charging issue.
I may just have to take the car in for a diagnostic. Or trade in this pos. I have a 2002 honda CRV with the motor from the same family as this with over 200k miles, zero problems so far.

Finally took the car into a honda dealership to have an electrical diagnosis. And just as I was expecting, they said the alternator is no good.
what a waste of time and $150 for diagnostic.
I even pulled the alternator out and have Autozone and Oreillys checked it and they both confirmed it was good.
so who do I trust?
honda dealer wants $650 to swap in their own alternator.
the one I bought from autozone was $180 and it takes me no more than 15 mins to do it myself, I've done it about 8 times now...
I freaking hate dealershits... and I beginning to hate hondas...
