Battery change somehow caused IOD fuse to blow
I changed my battery today in my 2006 dodge ram 1500. I'm not sure if one of the cables hit some metal or what, but my IOD(ignition off draw) fuse blew. I didn't even know what this was prior to reading this thread. So thank you all for posting. It was very helpful.
My locks, radio, and some of my lights would not work after replacing the battery. When I started the truck, the dashboard displayed a "No Fuse" message.
I wasn't sure what that meant. After searching this forum I found out.
It was the IOD fuse located in the fuse box, near the battery. The fuse box is a black case about 6" wide and 10" long. Once you open it up by pressing down on the top and pulling out, you will see the fuses and a diagram on the inside of the top of the box. It will denote what each fuse is responsible for.
When replacing the IOD fuse, you'll want to pull up the casing until it won't pull up anymore. Don't force it. Then take a small screwdriver and pry open the top part of the casing. Once open, remove the fuse and replace it with a new one. Make sure not to get the "low profile" fuses. The relays won't be long enough to plug in the way they need to.
Once replaced, put the small plastic casing back on, push the larger plastic casing back into its regular position and that should be it.
Everything was functioning after I replaced the IOD fuse.
Thanks again guys!
