Battery drains on my 2012 Ford XLT Super Crew. Bought a new battery which went dead after two days. Took truck to a garage and they replaced the alternator. After the alternator was replaced, the battery went dead after 2 days. This is when I noticed the high beams won't stay on. Found a post on Forum on how to reset time delay on Autolamp. After resetting autolamp the truck would run for 2 weeks and then battery goes dead. Took truck to Ford dealership and Canadian Tire hoping they could find problem and both said battery and alternator were fine. This is the third time the battery drained. Ford told me the best way to find draw was to put on machine to where it could take 1-5 hours to find draw. Need advice?

Battery full charged on Friday. Didn't use truck for 2 day and truck started this morning, charge is holding. Now to wait another 2 weeks for battery to go dead. Taking truck back to For dealership on Wednesday.

Parasitic drain? Wonder if you have something that still taps the battery once the key is off and removed. Dome lights?

No dome lights on. I was thinking ignition switch not turn off properly!! Seems like almost every 2 weeks battery goes dead. I went on vacation for 7 days, had truck parked. Truck started after vacation. Used for 2 days for work. I called in sick, didn't use it that day. Next morning, dead battery.

Do you have a back-up camera ?, If so check the connections for moisture. Also check the tail lamps and 3rd brake light for moisture.

No camera. In the off position I juggled key and I heard noise come on. My co- Worker owns 2011 Ford xlt so we did the same thing to ignition and didn't hear anything. Is there away to test ignition?

Ford Tech replace ignition switch. Fuel pump and dash lights turn on when keys is 1/2 in and wiggled. Retest and draws 0.03 amps and charging okay. Hopefully problem fixed! Will see in 2 weeks.
