HelloCustomer if you have no power inside the vehicle, I would start by focusing on the battery cables at both the battery and the starter post. Disassemble the bolt in the center of the battery cable and make sure the inside of the side post is clean and corrosion free. Also check for loose connections where the battery cable connects to the underhood fuse box. Let me know what you find and we'll conduct further testing if those items show OK.
Your JA Expert,
ok, give me a second and i will check that, thanks
You are very welcome, have a great night.
