at first - remove the alternator voltage regulator. Your carbon brushes maybe shot, check the idling voltage too. it should be 14.4V - not higher not lower.

when the alternator fails it illuminates the battery lamp, that battery lamp also illuminates all the panel as a precheck when you start the engine, so if it fails whilst operating you get all lamps lit again.
