What is the best way to determine what could be causing a parasitic battery drain?
Admittedly, I only drive my TJ once a week or so, but on repeated occasions I have to use my Jump Box to get the Jeep started. A few weeks ago in trying to diagnose the source of the problem I disconnected my winch from the positive battery terminal, thinking that it was causing the issue, but then again tonight the battery was dead after driving it for an hour or so two days in a row last week. Surely a battery that has been tested by both Auto Zone and O'Reillys and found to be in good shape should be able to hold a charge for a week. That leaves me with the assumption that some other accessory must be drawing just enough current to kill the battery. Thoughts in source and/or a method to track it down.
