## Discrepancy

THE 2-6050-27 HOSE CONNECTS THE ALTERNATOR COOLING PORT TO THE FLEXIBLE DUCT (SCAT HOSE) THAT BRINGS AIR FROM ABOVE ENGINE TO THE ALTERNATOR.  THIS NON-CONDUCTIVE HOSE HAD BEEN OMITTED (AFTER ENGINE CHANGE) WHICH ALLOWED THE WIRE IN THE FLEX DUCT TO CHAFE ON AND MAKE CONTACT WITH THE ALTERNATOR FIELD TERMINAL CAUSING ALTERNATOR/REGULATOR FAILURE.
