Description
Vehicle Compatibility
Complete alternator rectifier for 12V alternator applications where the alternator uses a matching 117mm outer diameter rectifier plate and the same diode configuration. Specified with a 50A rating and 7 avalanche diodes for compatible alternator rebuild work. Listed for select Ford applications including Fiesta and Focus (including TDCi) and also referenced for certain Volvo alternator applications where the rectifier specification matches. Confirm by alternator label, rectifier OD and terminal layout before ordering.
- Ford: Fiesta; Focus; Fiesta / Focus TDCi (applications using matching 117mm rectifier specification)
- Volvo: Alternator applications where the rectifier specification matches
