Voltage and RPM drops

In my 89 rs whenever i do anything electrical like tap the brake or especially the power windows my RPMS drop about 200 and the voltmeter drops from 13 to about 11-12. Also whenever my blinker is on my voltage gauge twiches a little. Any body know why cause i sure dont.

It's normal for the voltage guage to dip a LITTLE but not a lot like from 14-13 volts. A full volt drop is usually a sign of a faulty voltage regulator. I replaced my alternator and problem went away.
