Narrative:

During cruise at FL330; at night; an electrical malfunction occurred resulting in multiple bus failures; flickering of lights; loss of both pfd's and nd's; loss of flight guidance; loss of gfms; erratic/pulsating CSD needles; erratic and inappropriate CAWS alerts (too low gear; for example); loss of both navs; loss of VHF1; multiple flickering caution lights and a fail light on the transponder. Partial use of VHF2 was available.the captain had me declare an emergency immediately; which after several tries; I did with ATC on VHF2. We requested and received vectors to the nearest suitable airport. Emergency power was selected; to no avail; until the captain turned the left generator off. The APU was started and we landed safely although overweight at 136;400 pounds. No known ATC deviations occurred; and a normal approach and landing were made. Crash fire rescue equipment scanned our east&east compartment and confirmed no fire or hot spots.
