Installation & Maintenance Tips

  • Disconnect the battery before alternator removal or regulator replacement
  • Confirm the alternator is Iskra AAK and uses an A-circuit IR/EF regulator configuration before fitting
  • Inspect brushes, slip rings and internal connections while the alternator is open and replace worn parts as required
  • Ensure all charging circuit connections are clean and tight to prevent voltage drop and repeat failures
  • After installation, verify charging voltage under load and confirm charging light behaviour is correct for the application
  • If you are unsure about alternator repairs, have the unit fitted and tested by a qualified auto electrician
