## Discrepancy

PILOT REPORTED WILD AND ERRATIC READINGS ON THE GRAPHIC ENGINE ANALYZER (EIUBG-16( AND LOUD STATIC IN THE HEADSETS THROUGH THE RADIOS.  TROUBLESHOOTING REVEALED THE CAPACITOR IN THE LT MAGNETO HAD FAILED CREATING ARCING AT THE POINTS AND SUBSEQUENT RF NOISE AFFECTING THE UBG-16 AND RADIOS.  REPLACEMENT OF THE FAILED CAPACITOR FIXED THE PROBLEM.
