Check the Positive battery cable down to the STARTER. Check for a loose connection and/or break in the cable.

I had a Positive battery cable break down near the starter and lost ALL electrical power to the vehicle just like yours.

 

To give a quick update, was able to jump-start the truck this morning. Wasn't able to get the battery out last week, but am going to do that today for load testing, and replace if necessary (otherwise, will get it towed).

Thanks all for input and help! If battery takes car of the issue now, I will then start working trough some of the wiring as the weather lifts (possitive cable to starter, ground cable and connections, splicing to PDC, etc.).

 

I wouldn't be surprised if the battery was the problem. They can just fail.

 

Bit of an overdue catch-up, but it was the battery--thanks for the input and guidance all!

I also have found that the cigarette lighter is only powered when the truck is on or in accessory mode. My speculation on this is that the previous owner installed an aftermarket radio, and something got changed around in the installation process.

One thing that has happened since switching the battery is the RKE doesn't work--I replaced the batteries in the fob, but it is not interacting with the truck at all. Going to check the connection in the driverside kick panel tonight, but is it possible that it needs to be reprogrammed to the truck after not having a battery for a day?

 

I had this exact issue happen yesterday I thought it was the battery at first and tried to jump it but I noticed after a while the cables weren't sparking when I adjusted the cables. So I went to take out the battery to get it tested when I noticed I had a loose connection on my negitive terminal after tightening it my truck is working again. Hope this helps

 

Omg so happy to find y'all topic I'm having the same exact issue with my ram battery is good everything's in good looking order tight connections for my grounds it seems truck will run fine for a few days then all of a sudden one day get in Kia click all the way to the end lights will come on soon as I go to start it just clicks then all the lights flicker on my dome light and my ctm I can hear clicking it doesn't seem like I have any loose connections I'll double check though I do know I have a couple breaks in my negative wire one on the bend to the alternator and the other on the bench going into the fuse box they're not huge but you think that could cause an issue

 

Having the same issue on my 2000 dodge dakota slt 3.9l was working fine yesterday than went to start it up to head to work and it cranked over but didn't stay running so I tried again and that's when I lost all power

 

How's the battery? Battery cables? Do you get ANY power at all when you turn the key to Run?

 

Battery is somewhat new, the cables have a little corrosion on them, and there's no power like at all. The dome lights don't come on when u open the door and there's no binging when u put the key in the ignition when the doors open. But I did a little more digging into wires and found that one of my 12 volt battery wires for my radio was grounded out pretty bad for the wiring harness

 

Yep, verify your battery has good voltage. (north of 12 volts at rest) Check/clean both battery cables at the battery. See what happens.
