Electrical Problems, I have a short somewhere, Possible Solutions Options

[Cutrara]

Since Monday, a short somewhere in my wiring has been draining my battery (No, it's not the battery or alternator, I had them both checked) I took my car to get inspection/emissions and had them check it. He said the alarm was draining more power than it should. I pulled the alarm brain and disconnected the constant 12+, and ground wires from the alarm harness, and it's still draining. I have work all weekend and school all next week. I've designed a battery kill switch to cut off the battery as a temporary solution until I can diagnose the wiring problem over Christmas break.

Here is the kill switch I've designed:


Does this look OK for the application I'm using it for?
Would you improve anything?
Do you think something is shorting out?
Where do you think the short is?

Thanks,
Alex Cutrara

Ok, I was wrong about the EFI fuse. I pulled it and let the car sit overnight. The next morning my battery was dead. The battery is good. I did some more testing and found that the drain goes away when I pull the following things:

Disconnect Alternator Ground (The plastic case was broken on the fuse, and I didn't want to risk breaking it the fuse) If the alternator gets ground from anywhere, my test light turns on.
Pull 60A Main fuse under the hood
Pull EFI fuse 15A under the hood
Disconnect Alternator +
Pull Door 30A fuse inside car

My guess is that the short is in one of those circuits and the others are creating a false-positive by bridging a circuit.

Additionally, when I turn my car to "ON" now, my wipers are activated on the low speed.

Your help is greatly appreciated. Thanks.
