Optima dead, trying to find problem, help!

[Zedzag]

I have the DC FK35 running my dual LS1 fans and my battery went dead within two weeks right after the DC controller was installed. I'm not good with electronics so I had a friend of mine who's quite good (has his own electronics repair business) wire it up for me. I don't drive the car often so now I just unhook the battery. I haven't tried to troubleshoot the problem yet but my buddy does know what he's doing,the instructions were simple to read and well laid out, and the car has had no history of killing the battery in two weeks time(I've had the car for 14yrs). I rule out the DC controller as it is new but after seeing this post, it makes me wonder......
