Answer
# 1
Some times the exciter will we discharge due to the leakage or reverse supply at this condition we excite the exciter of the alternator, from 24 volt DC external supply for few time than start the DG it will generate the full voltage.

Answer
# 2
There is AVR i.e Automatic Voltage Regulator in Alternator. You need to check its settings. There are two knobs provided V+ to increase voltage & V- to decrease voltage of alternator.

If after increasing V+ there is no change in voltage at alternator terminal then check excitaion system.
 
Is This Answer Correct ?    2 Yes 1 No

# 3
Unless a proper load is connected to the set, the system will not work.
Consider the load to be current and then check the output.
