Remove the fan belt and run the engine. If they flash OK now, then the alternator or higher voltage must be the problem. If they still don't work, then the ignition system noise must be the problem.

Have you tried another flasher?

Tom, I have another flasher coming, but I was wondering if I could go to Advanced Auto, etc, and get a 3 prong flasher for a modern car equipped with LED signal lights at 12v.

I checked my grounds and they are good. Car is a new total retoration so lots of clean metal.

I tried adding a 1000 ohm resistance to the power input to decrease the voltage but it had little effect.

I will try the fan belt thing.
