Lights won't stop flashing on 96 Camry

I bought a 1996 Toyota Camry this summer. While I was away, my parents would start it every once in a while, and the last time they did the lights would not stop flashing. The hazard lights, glove box, clock are all flashing. I have the battery disconnected until I can figure it out. Any ideas? Thanks.

The trouble might be with the alternator. Disconnect the small wire connection on the back side of the alternator. Then start the car and see if the lights still flash. If they don’t then the alternator has some bad diodes inside it.
