My 1985 corvette runs but the voltage is high then low and if you use the headlights it takes the voltage down
Please help me out with finding what is wrong with it

We'd be more likely to be able to help you if you'd post some actual measurements.

Live well,

I would check my battery. A cell or two could be failing. The altenator could also be
starting to fail. Time to start checking things out.
Good luck
