That should be easier on the Sonett vs. new cars with computers all over the place.
Take your multi-meter, set to measure current (amps). Go to the fusebox, put one meter-lead on the spring-terminal on each side of a fuse. When you remove the fuse, any current that was flowing through that fuse is now flowing through the meter and being measured. Do this for all your fuses one at a time.
Each fuse should pretty much read zero amps as long as everything is switched off. If any fuse reads anything, try to explain it. Your clock should draw a very small current. Anything like 0.1 amps (100 mA) might be a small light bulb that isn't turning off (glovebox?).
This way you narrow down your search to the stuff that's powered through that fuse.
A large lamp like a headlight is 55 watts or about 4.5 amps. If some flaky cross-connection with poor contact sends 0.2 amps through a headlamp, it won't even glow dim orange. But it'll drain the battery.
I don't know if you're a audio-guy, but if you have component stereo stuff in the Sonett, make sure that all the modules are actually turning off. Some amplifier that doesn't switch off might be the culprit.
