What would cause all the lights to pulsate on a when engine is running on a 1985 corvette?

Generally this is due to corroded/ old/ poor ground connections.

Your engine, frame, battery, and electrical grounds must have good

clean connections especially on a fiberglass car. I suggest you

purchase some grounding straps and attach them to clean points

between these areas( You can't have too many). Sand off and rust or

old paint; this should solve the problem. A defective alternator

can do the same.
