Flickering or pulstating Headlights

Faulty voltage regulator will cause that. The condition suddenly appeared in my volt gauge needle a few days after I switched from amp gauge to volt gauge. I suppose I would have seen it in headlights, etc., also if I hadn't replaced the regulator right away.

I have been fighting this for a long time. I have every modification from this forum that I know of. It has improved, but I just can't get rid of the pulsation altogether. I could try another regulator, I have the old style, maybe there is one out there better than the others. Thanks a lot for reply...
