So I have been having this battery drain which I originally thought was because of an old battery. After replacing that with a new one I realized I was only getting 13.3v at the battery when charging, so I replaced with a new Alternator. I now get 14v at the battery and about 14.4 direct from the alternator. Problem is now if the truck sits for 3 or so days the battery is dead. Like wont even click the solenoid. So I tried to measure the draw on the battery. Disconnected the negative terminal and put a mutimeter in line between negative terminal and negative post. Set the multimeter to DCA and only get a reading on 200u of .2. Which is a super low draw I would think. So what is killing the battery?
