Dead Edge but Revived?

[tloewenberg]

I have a 3 year old (40K miles) 2008 Edge. About a year ago and just a couple nights ago, the car was fine when I shut it down. Lights off, doors closed, etc. The next morning, it was absolutely power dead. Nothing worked, no starter solenoid, no lights, nothing. In both cases, I got a jump and went straight to a Ford garage. Their diagnostic machine showed nothing wrong and plenty of crank left in the battery despite being discharged to almost nothing. All circuits checked out okay and they shrugged their shoulders, so did I after wring a check for the technician time. Even the car timeout circuitry seemed to work fine. Besides having something like a flakey relay or a sometimes ground, I have no idea and don't really have a good clue as to how to start troubleshooting or what to tell a qualified technician other than what's happened. Has anyone else had a similar experience? I've had no other issues except for a bad coil on one of the cylinders when I first owned it. Any assistance would really be appreciated.

Thx,

TL

I would start with a new battery. We already had to replace the one in our 2008. And we've seen a lot of cases where the battery seems to test ok but replacing it fixed the problem. If nothing else you get a fresh battery that you know is good for at least the next 3 years and you can rule that out of your troubleshooting.
