Electrical Issue After Battery Relocation

Electrical Issue After Battery Relocation

So I've relocated my battery and everything seemed fine key on engine off. Interior systems function with no issues. I attempted to move the car but after about 10 seconds of running my wipers started going crazy (not even switched on) and a cloud of smoke emitted from behind my radio into the cabin. To immediately rule out and prevent wasting anyone time this doesn't appear to be an issue between the battery and distribution block i.e. Short in the long power cable running from the trunk to the front of the car. But where the distribution begins and the power is distributed seems to be the cause. So this is the setup (see pic). I literally cut the three wires off the positive terminal, a 2 gauge, 8 gauge and a 16 gauge (approx) (see pic). The only difference is I cut out the 16 to 8 gauge connector that came from the terminal (see pic). Now this happens to also be the power to all the interior items and looking at the first picture the fuse that's blown. So in conclusion looking at the distribution block (pic 1) this is the only circuit of those three that blows causes my wipers to go crazy and burnt my radio up. Is there a resistor in that connector (see pic 3 again) or could this distribution block be crap? I'll take any and all suggestions please.

I replied to you on a different post... i didnt notice thar you werent the OP. Here's my teo cents from the info in the other post.

Based on your description above all of the power in your circuit is going through that one fuse. Is it possible that the circuits are bridged elsewhere in the car?

Also if you have a normal car battery you shouldnt be seeing a voltage increase while cranking. If anything it may drop to the maximum power of the battery (less volts but more amps). Is it possible you have the batteries in series not parallel?

If it were me, i would draw my circuit, then confirm each point on the circuit you imagine, vs what you have in the car. For me drawing my circuit always brings clarity.

Not judging, just trying to assist.

I would also stop testing the system live, you might be damaging your wire as it will be heating the wiring up until the resistance reaches a point where your battery requires 60A to over come it to make the circuit. Yiu may start a fire.
