Installation & Maintenance Tips
- Disconnect the battery before alternator removal or regulator replacement
- Confirm the alternator is Bosch and the regulator uses a round plug with 3 pin S L IG layout before fitting
- Inspect brushes, slip rings and rotor condition while the alternator is open and replace worn parts where required
- Ensure battery terminals and earth connections are clean and tight to prevent voltage drop and repeat failures
- After installation, verify charging voltage at idle and under load and confirm warning lamp behaviour
- If you are unsure about alternator repairs, have the regulator fitted and tested by a qualified auto electrician
