## Discrepancy

IN CRUISE, FUEL BOOST PUMP LIGHT ILLUMINATED WITH CORRESPONDING DROP IN FUEL PRESSURE.  LIGHTS AND RADIOS THEN BEGAN FAILING.  AS THE LIGHTS WERE DIMMING, FIRE WARNING LIGHT ILLUMINATED.  THE AIRCRAFT LANDED AT AIRPORT WITHOUT FURTHER INCIDENT.  GENERATOR FAIL LIGHT DID NOT ILLUMINATE.  THE STARTER/GENERATOR BRUSHES WERE REPLACED AND A FUNCTIONAL TEST OF THE STARTER/GENERATOR SYSTEM WAS SATISFACTORILY PERFORMED.
