I was driving my 2013 Ram 1500 SLT home last night and all of a sudden all electrical power went out. Nothing worked. I coasted to stop and tried to restart engine. Nothing at all. The headlights work only on manual, and the interior dome light worked. Nothing at all on any other electrical component when the key is engaged. No lights in when doors open or anything. I tested the battery and it read 12.7. Can anyone give me a clue as to what might be happening?

 

Broke this out, and moved it to the correct section for you.

 

ThadTurner,

Welcome to the forum. Sorry that you’re experiencing this concern. If you would like to PM me your VIN, I can look into this further for you.

 

Not certain in your instance but encountered a similarly weird situation a couple of yrs back. The boss and I had come out of the grocery store, loaded the grub, buckled up, turned the fobik and... nothing. No dash lights, no click, no fuel pump, no door locks, no interior lights... nothing! Played with fobik for a few minutes to no effect and just as I'm contemplating calling someone, I recalled some interesting discussions I'd run across about a year prior and related to some of the more recent auto electrical systems and specifically about some issues with seat belt and door open/close sequencing. What the heck - worth a try. I had the boss unbuckle her seat belt, then I unbuckled mine. Next I had her open the door, then I opened mine. Next we reversed that procedure and... well I'll be damned! Gremlins? Dunno but there is some anecdotal stuff out there that suggests that seat belt/door close sequencing can give the system a gun jam.

Cheers
