Question about Electrical Supplies
At first you should have nominal (rated) speed (1500 rpm or the written in your specification).
If you have it you should find your AVR (may be inside the alternator terminal box, or somewhere inside the alternator box), the voltage control trimmer and adjust to what you want the voltage to be. If not possible the AVR may be damaged.
The adjustment depends on your type of control system for the set as a whole.
If it is digital (computerized) the adjustment may also be digital.
If your system is too old it may have no AVR, but only transformed rectifier field supply. In this case you should check the transformer, choke (if any), rectifier and the condensers.
