You're going to have to do a "Parasitic Drain Test" and try to narrow this down.

Good luck. Hopefully the cross-cable business didn't damage anything serious.

may i ask like what? i am not car savvy at all.

Maybe the PCM. I'm not sure on that model if the PCM controls battery charging....or...possibly created a short circuit somewhere in the wiring.
