Car Not Starting... Battery or Alternator???

I'm having a similar problem in my '04 TL. I've read through this whole thread and am leaning towards the problem being a drain on the battery. I just replaced the battery yesterday for the same issue and it worked fine for the rest of yesterday and the first part of today. Now it's back to not starting again. The lights and everything come on when I get into the car and turn the key to the idle position but when I turn it to start the car everything goes dim and I just get a click or clicks. I don't think it is the coding of my key because I tried both keys and neither worked.
Could someone explain a little more about the possible HFL drain or whatever else the problem could possibly be?
Thanks for any input!

I had my 04 HFL unit replaced per that TSB ( http://www.box.net/shared/ahv7hm987a ) when it was still under warranty.
Also, there is another thread where someone took his HFL apart and replaced a capacitor for $1.50. Do another search for "capacitor" and you should find the thread. The unit itself is over $400 new.
edit: here's the repair thread, starts about the middle of the thread:

When you had the old battery tested (it tested bad and you replaced it), did you also have the charging system tested?
Have you checked for parasitic drain (bad HFL unit not shutting off, 200 mAmp drain)?
If your battery tested good one day and then bad only a few days later, I'd suspect faulty alternator or parasitic drain....
How long has your car sat between the problematic starts?
I assume starter replacement included the solenoid?
New starter or rebuilt. Brand?
Could also be faulty ignition switch.

sounds like a starter selenoid to me

the car sometimes starts in the morning but sometimes it takes me like 5 tries to get it to fire up it just clicks sometimes, itll start then turn off quick as well, ive replaced the battery and the starter (brand new, from autozone) i am going to get the alternator checked today and i orderd the HFL capaciter for $1.12 to have replaced incase that is what it is. Also it does it even when i shut the car off and the try to start it maybe a half hr later. Doesnt the starter solenoid come on the new starter when bought?

just got alternator checked, its cranking at 10 volts and i believe it is supposed to be cranking at 12 volts so i have a drainage somewhere battery and alternator checked out good. Any ideas, HFL?

With the car off for an hour you need to measure current draw at the battery and compare against factory spec to see if there is too much residual drain.

i had it tested at autozone they checked with car off then with car on idleing and with car running and idleing also with high beams and blower on battery tested at 12.56volts measured at 670 rated 600 temp at 83degress, cranking at normail with 10.99 volt 183.5A amps 843mS, no load at 14.27V w/ 4.0A and load at 14.07V w/ 2.4A and drain test at 0.93A

A bad alternator can cause the battery to drain till its dead. My suggestion would be to have the alternator and battery checked. I would personally check the alternator first, then if that is the problem, its causing your battery to die. Normally batteries have warranties, hopefully yours is in the year range. You can also fix the alternator yourself, its not too hard. I think there is a post somewhere on the website on how to fix it yourself, but that's up to you. Make sure you fix the alternator before you get a new battery or the dying will continue to happen from the alternator draining it. Hope this somewhat helps.

Voltage should stay at 14v no matter what you have running..
I'm not meaning to be rude but it's really hard to read your posts without punctuation and sentences. I'm not really sure what the rest of that means.

Hey people, I just thought I would update you guys on what happened with my battery issue.......
For me, the positive battery cable had to be replaced. It turns out that the guy who had the car before me replaced the positive connector terminal with an after market piece but didn't do a good job of taping up the end of the cable. When I first looked at the battery I noticed some corrosion around the positive terminal and cleaned it off. What I didn't realize was that the corrosion actually went all the way down the cable, the entire cable had been corroded. I had to cut away some of the plastic that wrapped the cable to see that the corrosion had continued down the cable. So I just replaced the cable and my TL is back to starting up like a champ!
I got the cable from an Acura dealership for about $49.00. Simple fix!
Thanks for the suggestions!

I myself have this issue with the starting and clicking noises. So stressful, when it first started to happen I replaced the battery immediately because I thought it was a dead cell, ok problem solved.....for a month and a half and now the same problem again. I believe the culprit is the starter simply because the battery is just to new. Will also be cleaning the terminal connectors with a wire brush. Sometimes those auto parts store test are BS(some, not all).
