"Phantom" Buzzer
Ok, so for awhile now I've had a "phantom" error. At seemingly random intervals, the error buzzer will go off. It usually happens after the car warms up and been driven, and not any time during a cold start, or idling in the garage.
The problem shows itself sometimes as a "ding ding..... ding-a-ding-ding" meaning that its not a constant ding'ing. Othertimes, it'll be "d-d-d-ing d-d-d-d-ing .. ding... ding" meaning that it will go off CRAZY for a few seconds, then just stop.
Now of course during all of this no error lights are on.
I know I could just unhook it, but I'd like to keep it there just in case the wife takes it out and a problem DOES occur .
Any ideas as to where to start or what to look for?

Ok, I'll bet on the oscillator, assuming your "ding-ding" is more like an "eerrnt-eerrnt" or something like that (different oscillators make different sounds, a nasty warning-like sound that eminates from some mysterious place behind the dash).
Up by the left front headlight there is a little black box with some wires and a connector going to it and the letters "Oscillator" printed on it (although these are sometimes hard to discern).
Unplug the oscillator, it will do no harm and if you don't here the buzzing anymore, it was the oscillator. Usually you can just plug it back in and the noise won't come back, so it's an all around pretty easy fix.
If not the oscillator (which you will determine by unplugging it), there must be a problem with one of the warning buzzers. But I've had three oscillator events and no problems with warning buzzers over the years.
Good luck!

NotveryHappyJack: not like that. It's clearly a mechanical buzzer sound, similar to , if not the same as, the low coolant buzzer.
The times my low coolant went off, the buzzer did not always buzz. It would stutter with like a ding, light comes on... light was on for a second or two, goes away and another ding when the light went out. There were a few times were it would ding during the process, but I've fixed the coolant problem now .
For what its worth, this is on a 82.
Doc: yeah, no lights during the process, but the light self-test at ignition on does show all lamps working.
