🔧 Installation Tips & Advice
- Inspect Stator Connector: Check the 3-pin connector coming from the stator for corrosion or burn marks (a common cause of failure). Clean or replace if necessary.
- Check Battery Health: A weak battery can stress even a brand new Reg/Rec. Ensure your battery is healthy and fully charged.
- Mounting: Unbolt the old regulator and mount the new one in the same location using original screws. Simple plug & play.
