## Discrepancy

AFTER TAKE-OFF, PILOT SMELLED SMOKE AND LOOKED AT GAGES AND ENGINE OIL TEMP SHOWED "0". PILOT TURNED AROUND AND LANDED. MECHANICS FOUND A LOOSE WIRE ON MAIN BUSS, BROKEN 10 AMP CIRCUIT BREAKER AND BROKEN WIRE AT VOLTAGE REGULATOR. MECHANICS TIGHTENED LOOSE WIRE, REPLACED CIRCUIT BREAKER AND INSTALLED NEW RING TERMINAL AND REPLACED VOLTAGE REGULATOR.  OPS CHECKS WERE GOOD AFTER REPAIRS.
