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

Are you saying that the only way the battery won't drain is if all those circuits are disconnected?

OK, it seems like the battery won't drain if the Door 30A fuse and EFI 15A fuse are disconnected. I charged my battery (almost to full) with a clamp on battery charger, and pulled those two fuses. I tested the battery periodically with my multimeter. In 9 hours, the voltage dropped .7V.

I will try cleaning the switch for the wiper switch.
