What are the symptoms of a faulty alt. on an fd?

 

Your "charge" light will come on. Letting you know there is a problem, be it overcharging or under.Then follow the FSM procedures for checking it.

Dead battery, charginging rate under 14 Volts DC( or in the near range)

 

More importantly, what are your symptoms?
