Description
Vehicle Compatibility
Complete alternator rectifier for Hitachi alternator applications where the alternator uses a matching IR/EF rectifier specification with a 9 diode layout and is supplied with diode trio. Listed for Nissan Cabstar diesel applications (commonly referenced as 2.5D) and also used on select Isuzu diesel alternators (noted as 2.8 diesel) where the OE reference matches. Confirm by alternator label and OE number before ordering.
