Sounds like the alternator is bad. Mine started doing the same thing when it died. You're battery isn't holding a charge due to the failing alternator and is running on fumes. Replace the alternator before you're battery life suffers from dying too much.

You can get a free charging system test at most auto parts stores.

Sounds like a dead battery.

But even with the keys not in the ignition? That's strange. Maybe something is drawing power that shouldn't be? Start pulling out the fuses and relays until you pinpoint which one is making the noise.

Waits for KoreaZJ...

I found wich one was making the noise but have no idea what it controls. Couldnt find it in the diagram in Haynes manual. took battery to get tested and its good so is alternator. No more clicking noise now that battery is charged and gauge shows solid 13 now but before it did also then would drop to zero while driving at highway speeds. Would stop and restart gauge would start at ten then drop to nothing.
