Honda: battery draining, amp meter, milliamp

Question
I recently bought my 1989 Honda accord.  It has been in an accident and the flip light was stuck up.  My battery kept on draining in about half an hour after the car was shut off, and I was assuming that the light was the problem.  I took the light off, and the battery seemed to be lasting longer, but it is still draining after a couple of days.  I went out and bought a brand new battery, so I know that's not the problem. Can you tell me anything that might be the cause of this?

Answer
the easiest way to find the problem is to connect an amp meter between the battery and the disconnected battery cable.with all the lights and accessories off there should be vary little draw somewhere in the 2 milliamp range.if you see more ,disconnect one fuse at a time until the draw drops.find out what is on that fuse and thats your problem.
