Have you measured the current draw with everything switched off? you should see some consumption if your battery is draining that quick. I'd pull fuses out one by one whilst watching the reading until it drops... Then investigate the circuit that fuse is related to... Something will be shorting somewhere. There may be a better way to do it but id start with that.

Could you please post your finding. I've a similar issue which was initially resolved by replacing the pink ignition relay which was causing the starter motor to fail to engage. You could test this by swapping the two pink relays in the fuse box area. However that did not fix my problem as my battery has dropped from fully charged to 11.8 overnight and the starter won't fire again.

Im told it's a connection problem between the relay and the starter motor.
