## Discrepancy

(CAN) PILOT REPORTED LOST GLIDESCOPE ON APPROACH AFTER LANDING GEAR WOULD NOT RETRACT.  GEAR SWUNG, ELECTRICAL WIRING INSPECTED, BATTERY REPLACED, VOLTAGE REGULATOR ADJUSTED (MAIN).   AIRCRAFT RELEASED AND TEST FLOWN - NO FAULTS FOUND.  COULD NOT DETERMINE CAUSE OF ELECTRICAL FAILURE EXCEPT  SUSPECT VOLTAGE REGULATOR WAS ADJUSTED TOO HIGH AND OVERVOLTAGE RELAY KICKED SYSTEM OFF.  IT WAS A COLD DAY, BATTERY WAS WEAK AND AIRCRAFT COLD-SOAKED.
