Description of Change: A new alternator is used in the charging alternator groups on the above engines. The former Delco-Remy alternators were discontinued by the manufacturer.
Adaptable As: The new 8T9700 Alternator (Nippon Denso) replaces the former 6T1194 and 9G6079 Alternators (Delco-Remy) in the charging alternator groups on the above engines. The chart lists the new and former alternators, the charging alternator groups, the engine models, and engine serial number prefixes. When a new 8T9700 Alternator is used to replace a former 6T1194 or 9G6079 Alternator.
...The wire that was connected to terminal 2 of the former alternator (see the illustration) is not used with the new alternator.
...The diode in the line that was connected to terminal 1 of the former alternator (see the illustration) is not required for the new alternator. The new alternator will work with the diode present, but the diode is not needed.
