## Discrepancy

WHILE TROUBLESHOOTING AN ALTERNATOR PROBLEM, FOUND THE OIL RETURN LINE ON NR 1 CYLINDER HAD ALTERNATOR WIRE HARNESS TY-WRAP TO IT.  REMOVED TY-WRAP TO INSPECT THE WIRE HARNESS, AND THE LINE WAS FOUND CHAFED MORE THAN 75 PERCENT THROUGH THE WALL THICKNESS.  SUBMITTER STATED TY-WRAPPING WIRES DIRECTLY TO THESE ALUMINUM LINES IS COMMON, BUT SHOULD HAVE SOME KIND OF PROTECTION FROM CHAFING.
