I replaced my old battery less than 2 months ago in my 2008 Honda Ridgeline. After sitting idle for 3 days over xmas, truck would not turn over. Jumped it and drove it for a few errands that day. Next morning, truck did start but turnover was quite weak. Did not drive truck for another day or 2 and was dead again on next attempt to start. I made certain nothing was left on (dome lite, etc.). I tried jumping it this morning (100% dead, fob would not even unlock doors) and as soon as I hooked up jumper cables for a boost, horn / alarm started going off (have read several forums and believe I know how to prevent / stop this now). I was not able to get the truck started with the boost (??) at this time and have not had an opportunity to try again yet. Short of a defective battery, How / where do I start to try and find out what is draining the battery?
