Hidden electrical draw

I have an 06 SI with no mods - stock radio. I bought the car a month ago and when it sits unused for 2-3 days the battery dies. When I drive it daily it is fine. The car has a new battery and my mechanic checked all the obvious solutions (battery, alternator, wiring).
He has found an electrical draw coming from the fuse compartment but he says he does not have the expertise to take it further suggesting I should take it to a dealer.
My questions:
- Has anyone had a similar issue and is there a DIY solution?
- I have an OBD reader, would that give me any info to go by?
- If I have to take it to a dealer what do you think should be their proper testing sequence? I do not want to be charged for non-necessary tests.
Any advise would be highly appreciated, I think I may be looking at a major expense here.
Thank you.

if you have a multi meter. disconnect the negative battery cable. Connect the multi meter in series with the negative cable, set on amps. pull one fuse at a time until the amps drop. You can narrow it down to the circuit that way.

EDIT: Approximately what amperage should I be looking for for a small leak that take a few days to drain the battery?
Also, where do I find a guide for my fuse box (06 Civic SI)?
Thanks.

If you have no experience in using a DMM, just bring it to a dealer and make sure that no kid touches your car. Make sure its a journeyman that knows his electrical stuff.

The AC relay does not need to buzz in order to be deemed faulty. If it's stuck on, there will draw of 100+mA (max or 60 for honda). Your mechanic told you that he does not have enough experience to diagnose it and he's right because, not only experience, but also he probably does have access to the complete electrical schematic of your vehicle. Best bet is take it to the dealer that has access to it (obviously). Stop taking guesses. Fix it right the first time.

Also, if you have an aftermarket remote starter, the remote starter command module can stay awake and cause draw of 60-100mA depending on the remote starter.

I can give you a full power distribution of every single fuse in there but that will take 10 months to do so don't waste your time and go the dealer. lol

Just pull a fuse at a time and replace it until you see a significant drop. Try to narrow it down that way. Don't do it right after driving because there are certain systems that take take a few minutes to go to their low power state. Also, if you have the door open and dome light on, when you pull that fuse the draw will drop. Just be aware of those kinds of things. I had a parasitic draw on one blazer I had that I narrowed down to an after market cd player pretty quick. If you have any after market ee1uipment, it could likely be the issue, not a guarantee though. Give it a try before getting charged a couple hundred dollars at a dealer.

Does your car have hands free link? Those control units can pull a draw of ~ .250A when they're failing. Actually sometimes they will cause a draw and still operate. I see this on some Acuras. When you get an amprobe to measure draw, take your key out of the car, use a pry bar or long flathead screwdriver to push the hood latch into the closed position (keeping the hood raised), lock the car and arm the security, wait about 15 minutes and measure the amperage draw on the negative battery cable. If you have ~ .225-.250A, unplug the HFL unit and repeat the process.

Forgot to say, normal would be ~ 0.042A or less.
