1991 240 volvo battery problem

Standard alternator voltage output depending on temperature and load should be between 12.4vDC and 14.1vDC. What you are reading is battery voltage. A good battery with decent charge should show ~12.4-12.7vDC. It's likely the alternator brushes/regulator are very near the end of useful life and need replaced.

check the earths and wiring harness for that circuit. Pay attention to the + which runs under the engine and is known (on early 240's) to degrade and cause issue.
