Nonsence my good man.... Anyone with a CD player can tell you that
Aerosmith, Sabbath, or Zepplin played **loud enough** can keep that pesky
voltage down just fine.

I had an old merc with the unregulated charging system. It will fry an
automotive battery. You need an old style marine battery to hold that
voltage
down or get the new style regulator/rectifier. Light bulbs take a beating
at
16v and I actually melted my running light lenses.
