Please help, I have an 05 and for some time now the battery does not hold a charge over night. I have replaced the alt. and battery. When the car is running everything is working fine, the batt. is getting a charge from the alt.

A link to a link...

 

I know.... both threads have good info though so he has two sources to read from

 

Have you done any mods to the car at all? Added a aftermarket sub/amp? I remember seeing a thing in the past about amp/xm radio staying hot after car is shut off. Take a test light and check the fuse panels on driver side, passenger side, and under the hood.

Go to this link and download service manual https://acurazine.com/forums/2g-rl-2005-2012-76/service-manual-1-download-856199/

That should help you diagnose which circuit is staying active

 

check if the trunk light or dome lights are not go off... something is draining the battery!!

 

I hoped as much. I just went straight to post five.

 

thanks all, this is bull its been 8 years now and acura does not have a fix

 

you are telling me that in 8 years no one has taken the time to track down the draw on the battery?

 

Ive noticed a lot of owners are not exactly diy people and leave it to dealers

 

You can't teach an old dog new tricks....

 

right on...

 

I though Acura had a fix for both potential battery drain issues. You can't blame them because they didn't come out to your house and fix it on your time.

 

I had this same problem last year (also an 05) and my car was at the dealership for 3 weeks while they looked for the problem. And while it was there I had them figure out why my sub stopped working. Turns out that my radio had an internal short, fried my sub and was draining my batt. with a 5 amp parasitic drain while my car was off. So anyway new head unit and new sub and some wire repair and haven't had the problem again.

 

5A!!! I wonder if that's what killed the subwoofer that melted the other day.

 

I was thinking the same thing, if he posts up his battery is draining we will know why.
