Left it connected for 15 this morning to my other car, same thing, turn the ignition to start and everything dies. Accessory position is fine, dash lights up, etc.

The Battery is 2 years old, but shows a 12.5v charge on the multimeter. I left the lights on for about 5 minutes before testing it, and they never got dim.

Hi all, My ford edge has an unusual issue. It first happened about 3 months ago, was at the neighborhood store, came out to the car, and when I turned the ignition, I lost all power. No door locks, no dash/headlights, nothing. Went home, brought another car up, and the second I hooked up the jumper cables, the headlights turned on, and then the car started. Ran / started fine for the past 90 or so days. Yesterday, the same thing happened, but in my driveway. This time however, the jump doesnt work. I disconnected the battery, cleaned the terminals, and when I re-connect the battery, the lights turn on. I can turn the key to the first position and the dash lights, and radio all work. But if I continue and turn the key to start, everything goes dead again, and i need to disconnect/reconnect the battery to get the dash lights/etc to come back on. The only icon that is on when the power is completely dead, is the little security lock in the lower left corner- it flashes about every 3 secs. Not sure if that's the culprit, or if it's something else. I tried both keys I have for the car. Both have the same effect, - turn the car to start and lose all power? Any ideas, or has anyone seen this behavior before? Thanks in advance Pike
