Erratic Voltage ?

High guys,
Its been a while sense my last post. I just went through a lot of scambling to get my 89 911 to pass its inspection in TX.

Thankfully this forum exsist to help many diy guys. Had I read enough here I could have helped the guys working to fix my problem. Long story and not enough time tell tonight. However my voltage seems to be a prob. My lights get brighter and my A/C fan blows harder. In TX I don't mind the A/C blowing harder but, I'm afraid it might damage somthing. I plugged in a volt meter in the cigarette and at low rpms it reads 12-13 volts as I drive down the highway it reads between 16-18 volts. This can't be good. Might it be the brushes or the regulator. I have not pulled the alternator yet. Just asking for wisdom before I get into it.
