Installation & Maintenance Tips
- Disconnect the battery before alternator removal or regulator replacement
- Match the regulator by Nippon Denso manufacturer, A Circuit design, and the 3 pin S IG L round plug connection
- Confirm the mounting footprint, including the 63.5mm mounting points diameter, matches the original regulator
- Inspect brushes and slip rings while the alternator is open and replace worn components 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 to confirm stable regulation
