## Discrepancy

APU WILL NOT START.  STARTER APPEARS TO WORK BUT NO EGT OR RPM RISE.  FOUND APU START/GEN GROUND CABLE MELTED DUE TO ARCING BETWEEN GENERATOR TERMINALS.  ALSO FOUND TERMINAL ON START/GEN TO BE MELTED.  REMOVED START/GEN AND GROUND CABLE AND REPLACED WITH SERVICEABLE UNITS.  REMOVED AND REPLACED APU GCU WITH A SERVICEABLE UNIT.  OPS CHECK GOOD.
