Your voltage regulator is inside the alternator. Check the page below for a troubleshooting guide.

If you don't know how to perform those steps, take it into your mechanic because the best case is that you will spend unnecessary money on a new alternator. The worst case is that you will burn up your alternator, battery, cables, and other sensitive electronics in your Volvo.
