Locating short - A1286 2.3GHz i7-3615QM - 820-3330-B

[xalu]

Hello, I have a macbook pro 820-3330-B logic board that's giving me some issues. I had it post with chime without the display connected. When I tried to connect the display the board stopped going to post (no chime).

Now when I plug it in it starts itself (w/ or without the display connected) and it slowly spins the fans. They spin up then spin down. I am getting a 12v reading at the fuse near the lsdv connector that jumps up and down. I believe the connector on the display was damaged causing the issues.

I was wondering if I could get some help locating the short? Also, can someone supply me with the board view (and schematic but board views more important).

Other issue it's having is it won't charge the battery. I can't shut it down, I tried doing the SMC reset but it turns itself back on when the plug is attached. It will not start without the plug even with fully charged battery.

Thanks!

So I realized I put the battery plug in backwards. The battery is from a 20120 and this board has the plug tilted 90 degrees and the plug goes in the other way around.

Now, when I plug in the battery and cable I just get a green light. Won't start and no reaction from keyboard. The battery check button flashes.

Looking at the board view of the board that the battery came from I am seeing that the wiring order is different. Is this true? Will a battery from an 820-2850 work in the 820-3330?

Did I fry the board by doing this? Or do I just need the right battery? (If no one knows/answers I'll try to remember to update here when I try it out with a battery for this board.
