First time, battery connected, then I went to disconnect it (thinking maybe the battery is fked). Both times, HUGE sparks went flying and shit started to glow 🥲 I'm planning to do that next, unplug the alternator. Just a bit of a pain in the arse due to the plenum and DBW, but needs to be done. Threw sparks even when I just touched the +VE jump point, even before letting go of the clamps. Good point about the amps, there's a 8 gauge going to a fuse block that splits into 2x 12 gauge. Going to be a fun process of elimination -
Random thoughts, is it possible positive jumper lead was touching either that metal box, or the oil line beside it? And just double check with battery disconnected there cables/connections aren't touching/resting on car body/other conductive material. It could even be an amp cable has come lose and is shorting, however I suspect you have fuses close to the battery for amp power supply and they would have popped (though if one only have melted, it could be why you have a higher resistance to earth now and it's not popping, so I'd double check amp wires/fuses) -

Thanks for the kind words! Feel free to ask anything, anytime. Cheers. -

Haha thanks! Our 4 seasons here are a great motivator to get things running for the summer season. -
When they started to glow and crazy sparks, was the battery still in the car and connected to POS and negative? What sort of battery is it? (Lithium, lead acid, etc?) Is it possible you stuffed up the jump start and managed to get both POS and neg cables on a dead short through the skyline? Check the resistance again, then disconnect the power cable on the alternator, and then measure that same resistance from POS pole to earth. Then measure alternators POS pole to alternator body (with cable disconnected). Do the same on / with the starter motor.
