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

Unless you get a big enough relay you'll burn it out. Running all of the car through a single relay might not be a good idea anyway. If you just want to disconnect the battery you can get a connector that goes on your battery that has a big knob on the top you just unscrew to disconnect it. Look where the battery cables are at your local NAPA/Autozone/Big Earl's Car-o-Rama.
