Take a look in the battery junction box - the fuse box under the hood. If you had battery leakage, it could have corroded or damaged wiring in or around that box, which could be causing a short. In my experience, always go to the variable. The area where problems once were. Sure you could trace all the wiring on each circuit, but in the end, most of the time you find the issues are close to where you previously had a problem. Good luck.
