2011 Transit Connect, 70,000 miles. Battery completely dead if truck not used for 3 days or more. Battery is 2 years old and healthy. Will start instantly when jump started. Nothing left on such as lights, nothing left in cig lighter. Thinking a parasitic drain of some sort. Thoughts,suggestions?

G B L is right. You need a ammeter in series with the battery that reads millivolts (mV). Anything over 50 mV is too high. The fuse pull trick will tell you which circuit is affected, and you can go from there. Aftermarket accessories are a common cause, like  a LoJack or something like that. Good luck.

Thanks Don a good catch, as english is not my strongest skill.

The computers in the tc all require some power to matain memory.  There  is always some draw.  You need an accurate ammeter with a low enough scale to see what the actual draw is and is it enough to kill the battery.
