2002 540 completely dead, electrically

I unlocked the car with the key, which worked normally, got in, put
the key in the ignition and NOTHING happens. Nothing works. No
lights, no started click, nothing.

All suggestions appreciated.

Possibly a main, central fuse has burnt. I guess you have checked the battery.

The problem was the battery. It was down to about 3 volts. If it will
take a charge tonight, the next question will be why it went down. It's
only 2 1/2 years old.

Thanks for the input.

Sorry for the very slow reply. I actually fixed it the day I started
this thread. My kids and grandkids were around and I didn't have
a chance to get back here.

Even though the battery terminal wires seemed just fine the negative
terminal wasn't. I took it off, brushed off the terminal and connector
and things worked fine. I put di-electric silicon grease on it and
everything is fine. Apparently when the battery was replaced a
couple of years ago they didn't put on the "grease".
