Alternator Problem, please help...

[duce_n_135]

Hello, I just recently bought a 93' 240sx shell. It has an sr swap previously and now when i put the ka24de back in it, it drains the battery like no other. I did a check, and found out that when i plug in the alternator plug, it shorted out the whole car. There's continuity when i test the plug. It's weird. Any idea of where this short could be or what cause this problem? i literally rip out every wire trying to track it out.
Thanks in advance for the reply.

check under the terminal on the alt, there should be a plastic washer. if its gone or broken, it will short the main fuse. good luck.
