Features: This voltage regulator provides a stable output voltage, meaning your battery will get the exact charge rate it needs at both low and high RPMs. Heat is dissipated via the central aluminum heat sink. The rectifier bridge inside is very efficient. However, as with all models, we recommend paying special attention to installing the regulator on a clean surface and securely fastening it with bolts. This will ensure good thermal contact between the regulator and the chassis, which is necessary for heat transfer. Please read the information above carefully to ensure this part is suitable for your vehicle.
