Specs At A Glance

Good To Know

Q: How do I know my regulator needs replacing? A: Common signs include a battery that will not hold charge, dim or flickering lights, and voltage readings outside the normal range while the engine runs.

Q: Do I need to replace the stator at the same time? A: Not always, but if the stator shows signs of damage or the charging output stays low after fitting a new regulator, testing the stator is the next step.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
