What was found
ALTERNATOR LOWER ATTACH BOLT PULLED FROM BRACKET CAUSING LOSS OF BELT TENSION AND SUBSEQUENT BATTERY DRAIN AND INTERRUPTION OF RADIO CONTACT. BOLT HAD ONLY ENGAGED TWO OR THREE THREADS IN MOUNTING BRACKET BECAUSE OF TOO MANY WASHERS UNDER BOLT HEAD. WITHOUT WASHERS, THE BOLT WOULD NOT THREAD ALL THE WAY INTO THE BRACKET UNTIL DIRT WAS REMOVED. WHEN DIRT IN BRACKET WAS REMOVED AND STACK OF WASHERS REMOVED, ALTERNATOR COULD THEN BE MOUNTED SECURELY WITH ADEQUATE ENGAGEMENT OF BOLT.
