Flickering or pulstating Headlights

Must just be the old style regulator causing the flickering. I installed a voltmeter instead of using the ammeter. It gives you a better idea of what is happening with your charging system.

I have a voltmeter, it bounces between 13 and 14 volts, the Mad bypass does away with the Ammeter. I can try another regulator if you think it will fix it. Do you have any recommendations? Thanks again
