DURING INSPECTION, FOUND WIRES FROM TERMINAL A1 OF K310 BATTERY RELAY TO BATTERY SHUNT AND WIRES FROM THE BATTERY SIDE OF REVERSE CURRENT RELAY TO TERMINAL A1 OF K301 START RELAY HAD SEVERELY CRACKED COVERING EXPOSING BARE WIRES.  THESE WIRES ARE CLAMPED TOGETHER AND COULD HAVE STARTED TOUCHING EACH OTHER AT ANY TIME.  ALL OF THESE WIRES SHOW 'NO' SIGNS OF HEAT STRESS OR OVERHEATING.  THE CRACKING APPEARS TO BE FROM OLD AGE.
