# Regulator rectifier

> A regulator rectifier converts the stator's AC output to DC and limits the charging voltage to protect the battery and electrics.

- **Also known as:** Regülatör, Redresör, Şarj dinamosu düzenleyici, Voltage regulator
- **Turkish term:** Konjektör (regülatör)

With the engine running, a healthy charging system on most models shows about 13.5–14.8 V across the battery terminals (see the manual for the exact value). The regulator turns surplus energy into heat, which is why its finned body gets hot.

## Symptoms of a problem

- **Not charging:** the battery keeps going flat and voltage does not rise with revs
- **Overcharging:** voltage above 15 V; the battery swells or boils, bulbs blow frequently
- Burnt or melted connectors

Before replacing the regulator, also measure the [stator](https://motorsikletparcasi.com/en/glossary/stator) output and check the wiring.
