Battery replacement leads to IOD and seatbelt fuse blowing, dying battery
Hey guys, I've been reading over the site the past couple days, but I'm not very car savvy.
I recently bought a 1999 Ram 5.9 v8, only has 55,000 miles from one owner. When I bought it, the interior lights and radio didint work. No problem, its a work truck. All worked just fine until one day I pulled it out of the driveway to blow the driveway off after cutting grass. When I went to pull it back in, it was comepletely dead. Went from perfectly fine to absolutely dead in less than 20 minutes. I bought a new battery and it cranked again, but the seatbelts were locked up which they weren't before the battery swap. I looked in the fuse compartment and the number 16 seatbelt fuse pops instantly, same thing with the number 12 IOD fuse.
I drove it for about a week with no seatbelts while trying to research the issue. I went out a few days ago and the battery was comepltely dead again. Trying to jump it with my car and even putting a 120v battery charger on it wouldnt do a thing to it. I swapped the battery out, and it cranks again, but the fuse issues remain. I tried to plug an OBD2 reader in, but of course that doesn't get power.
Any ideas on what to do and where to start?
