Trouble shoot a charging system problem. Car tested with alternator out of car both battery and alternator tested as okay however the system is not charging. Dash meter shows volts low no charging when engine runs. And no fluctuation when lights are turned on with engine running. Other test performed with engine running positive post loosened. Which means if engine stays running generator is working instead engine stops. How can alternator test as working but installed it isn't charging? My voltage regulator is built into alternator.
