Have you tried jumping it? If space is really tight a jump box might do the trick.
I have not but I’ll now based on the responses here. I really didn’t think it was the battery but it sounds like I may be wrong.Have you tried jumping it? If space is really tight a jump box might do the trick.
Pardon my ignorance, but what should I be looking for on the fusible links? Would it visually look broken/melted or I need to test it for continuity? Also, how do I check the battery ground? There is nothing obviously visible so far, everything looks brand new, no corrosion.Check the fusible links on the positive terminal for a blown fuse, the battery ground, and terminal connections. If something looks corroded to shit, clean it up and apply some dieletric grease acter you recconect them. Let us know if you find anything.
Ok, thanks - I’ll try testing it and jumping it as well.Another thing I'd like to add: don't be so quick to rule out a dead battery. Even though it's new, you might have a parasitic draw, or a faulty battery. Batteries usually have warranties with them, so you shoyld be covered if that's the case. Get a multimeter and start probing.
This is a really good comment. When I got my truck new, the battery terminals were already corroding. I got replacement cables under warranty and also greased them.Check the fusible links on the positive terminal for a blown fuse, the battery ground, and terminal connections.

I had to clean mine every six months or so on my '16.This is a really good comment. When I got my truck new, the battery terminals were already corroding. I got replacement cables under warranty and also greased them.
The exhaust from my 5.0 Cummins can set off alarms…Update: it was the battery after all. I tested the battery and it was reading only 4 volts - never seen one this low!
Jump started it using a jump battery pack, drove for half an hour and let idle for another hour - shut down and it read 12.7 V with the engine off. Tried restarting the engine and it fired up just fine - so it doesn’t seem like the battery is faulty.
Not sure what could have possibly drained it a new battery like that, any ideas? My only theory is that perhaps one of many strong thunderstorms that went through the area last week set off the alarm which then drained the battery - but that still seems pretty far fetched.
I cleaned and greased my terminals/connections several months ago, and they still look great. I'm thinking about greasing the large connector on the frame, passenger side. It sits in a vunerable spot.I had to clean mine every six months or so on my '16.
Even though you fixed it, for future reference: fusible links have some clear plastic sections with a zig-zag piece of metal behind them. It's just a really big fuse. So what you'd look for is blown fuses, which are usually accompanied by burn marks. If there's a small gap in that metal path, your fuse is blown.Pardon my ignorance, but what should I be looking for on the fusible links?
