I think I'm having some overall electrical issue, but need some input.
2012 Ford F150 XLT
I don't drive it a whole lot, but been running fine. Made a two-hour road trip over the weekend and ran fine, but when I went to start it back up to head home, nothing. Engine didn't turn over, no clicking, no dash display, no headlights, no interior lights, totally dead. I got a jump and managed to get it started so thought a dead battery. Drove out of the parking lot and for a split second felt like the power steering went out. Got back on the road and everything was fine. Stopped to get gas (left it running) and when leaving the gas station power steering went out for a split second, ABS and traction control lights blinked on, dash lights blinked off. Got on the road and everything was fine for the two-hour drive back home. Got home and shut it off, tried to start back up and the whole thing was dead. Wouldn't turn over, no clicking, no interior lights, no headlights, no dash display, and had to manually unlock the doors (key fob didn't work). I had the starter and ignition tumbler replaced less than a year ago. Any thoughts from anyone out there?

 

Have you had the electrical system tested? How old is the battery?

 

I'm not a mechanic, but I do own an '11 Ford F150 Lariat Supercrew 4x4, LOL. A lot of research in these bones. My truck sits a lot these days. That has to do with the price of gas, politics, being on disability and a Lack of funds. A Car/Truck should be driven. Besides Rust, when a vehicle sits, it does a lot of unseen damage, especially with todays electronics... Do you have a Multimeter? If you do, check the overnight resting voltage of the battery. In the morning, after letting the truck sit over night, Open the truck up, pop the hood latch, shut the door, open the hood, and let the truck sit for about 10 minutes before you check the battery voltage. The Electronic nanny's need a few minutes to settle. Voltage of a fully charged battery should be 12.7V or above. If you're down to about 12.2V you're at about 60%. At that level you'll definitely have starting issues. First time mine was dead nothing worked. I tried to use the remote start one cold morning and nothing. Went out and had to use the key to open the door, and even didn't click trying to start it with the key. Put it on charge for four hours before it would start. Had no warning. Common for a "Sudden" dead issue.
