2006 TL battery will die if sitting for a couple days. Using test light, found the draw to be coming from the fuse #15 under the hood, because the negative terminal ceases to have current pass through it when I pull that fuse. I found online that this fuse powers the driver's side door panel fuses 5, 6, 7, 8, & 9. However, when I pull each of these out individually (with #15 still in) there is still a draw in my test light. So I'm not sure where to go from here. I also replaced the AC relay under the hood, still have a draw.
Any ideas on how to diagnose further and solve this issue? Thanks!
Have you tried disconnecting the HFL? This is a very common issue with the 3G TL. HFL doesn't shut down after ignition is turned off and will continue to draw down your battery and will kill the battery if left sitting for a few days. There are many threads here on Acurazine about it. Not sure off the top of my head it the fuse/relay you have replaced are tied to the HFL or not.

I should have mentioned, the HFL has been disconnected ever since I bought the car. So I know it has nothing to do with that, but I appreciate the feedback!
Pull each fuse that under-hood #15 feeds. There are couple relays as well but I doubt it's any of the lights relay. Don't use test light to measure current!!! There is no way to accurately measure anything with it. Either use voltmeter to check voltage drop across each fuse or amp clamp to measure total current.

Agree with peter6. I would strongly recommend using a amp clamp or the ammeter function of a DMM.
I HAVE A 2006 mdx and the battery dies often if i dont drive it for a week..its weird..i have replaced the battery 3x from costco on warranty replacements but still happens like something is draining it..but its parked in the garage and never use the alarm/locks when just stilling there....I have yet to figure pout whats draining it.
Of course I'm just guessing. No way to know for sure without checking. Also I guess I was thinking about next generation of MDX to yours. Seems '06 have it around dome lights.
