Alternator Rectifier 120mm 35A 8 Diode 12V VW Jetta GTI Audi Seat Skoda Bosch Type RCT1016
Vehicle Compatibility
Complete alternator rectifier for 12V Bosch-type alternator applications where the alternator uses a matching 120mm outer diameter rectifier plate and the same diode configuration. Listed for VW applications including Jetta and GTI, and also used across Audi, SEAT and Skoda alternator builds where the VAG OE references match. Specified with 8 diodes and a 35A rating for compatible alternator rebuild work. Also cross-referenced to multiple BMW, Mercedes-Benz, Opel, Saab, Volvo and Fiat-group numbers where the rectifier specification matches. Confirm by alternator label, rectifier OD and OE reference before ordering.

- Common VW Jetta and GTI coverage where VAG OE references match the rectifier specification
- Supports alternator overhaul where failed diodes cause low charge, battery drain, or excessive AC ripple
- Best practice is to confirm rectifier diameter and OE reference to avoid incorrect fitment on similar-looking rectifiers
Why Buy From Us
- Local South African stock with nationwide courier delivery
- 12-month warranty subject to correct application and installation
- Fitment support using alternator labels and clear photos of the existing rectifier and terminal layout
- Trusted by workshops and fleet operators for dependable charging system components
Trusted by thousands of South African drivers for quality and durability.
Installation & Maintenance Tips
- Disconnect the battery before alternator removal or rectifier replacement
- Confirm rectifier outer diameter (120mm) and diode layout (8 diodes) before fitting
- Inspect stator windings, solder joints and insulation while the alternator is open
- Replace worn brushes and check slip rings during the rebuild to prevent repeat failures
- After installation, verify charging voltage under load and test for abnormal AC ripple
- If you are unsure about alternator repairs, have the unit fitted and tested by a qualified auto electrician
