While driving home tonight, all but three of the instrument warning lights came on, and won't go off. The only ones NOT on are the SRS, Check Engine, and ABS lights. The car starts and runs fine... for now. Any ideas as to what might be wrong. 
 
Thanks in advance.

Keith, My .02 worth would include a check of your OVP(over voltage protection)relay. Most circuits are tied to that. I recently had everything shut down because the 10a fuse(in the relay)had vibrated loose. Tightened the contacts and the car('85 500SEC euro)is running like new again. Good luck, John F.

It was the alternator belt. It snapped. $14 for a new one, put it in myself !!
