## Discrepancy

LEFT AND RIGHT ALTERNATOR BELTS WERE REPLACED WITH NEW BELTS AT PROPELLER OVERHAUL.  WITHIN APPROXIMATELY 3 HRS, THE RT BELT FAILED DUE TO UNKNOWN REASONS AND LT BELT WAS SLIPPING DUE TO METEROLOGICAL CONDITIONS WHICH RESULTED IN LOSS OF ELECTRICAL POWER.  RE-ADJUSTED TENSION ON LT BELT AND INSTALLED NEW BELT ON RT SIDE AND ADJUSTED TENSION.  PERFORMED ABOUT A 15-MINUTE RUN-UP AND RE-CHECKED TENSIONS.  RECOMMEND CHECKING BELT ALIGNMENT AND RE-CHECKING BELT TENSION AFTER A GOOD GROUND RUN.
