Anyone experienceing their battery slowly draining over a period of time ? I noticed this after I would leave it sit without starting it for awhile. At first i just thought it was the stock battery going bad. Then I Installed a brand new Oddyssey PC925L and its doing the same. I have disconnected all of accessarys I have Installed and i stll get a light spark when I connect the Battery Ground cable. I will continue to isolate circuits starting with the dash and ECM as I suspect they may have on board memory that needs a constant +12vdc.
