Too high voltage (above 15v or so) is very bad, and can burn out a whole list of stuff.

I just replaced the alternator in one of my cars. It was putting out about 19v. The lights would really dim when I popped into neutral while driving.
After burning out a few headlights I finally got smart and got another one.

Generally, the system voltage on most vehicles while running should be 13.5-14.5 volts. More importantly, the difference between the voltage reading with the engine running should be no more than 2 volts or so above the reading with no loads on after the vehicle has sat overnight (that's true open circuit voltage). Since OCV should be 12.5-12.7 on most batteries, charging voltage should be below 15 for sure.

Replace your alt. ASAP before you grenade your battery.

and yeah i blew out both of my high beams already, i just thought it was because they are the same lights that were already in the car that has been sitting for who knows how long

The 18 volts was the straw that broke the camel's back.

And yes, definitely get the regulator fixed before you nuke the battery!
