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.
