You might want to start by checking for damage to a) the fuse box and b) any of the "fusible links" that are inline from the + on the battery post.

With this type of electrical fire, there's no way to pinpoint the damage until you start digging into it---starting with the simplest things first--fuses, melted wires under the fuse box, fusible link failures, condition of the battery.

You may need to take it to a specialist who has wiring diagrams and scan tools and can diagnose this step by step and inch by inch in the wiring.
