Installation and Maintenance Tips

Before installation, check the drive belt condition and tension; a loose belt reduces charging efficiency. When connecting, ensure correct wire polarity and solid ground connections. Given the significant weight (12.32 kg) and compact dimensions (34 × 24.5 × 25 cm), professional installation in a workshop is recommended. After mounting, test the engine and measure charging voltage at idle and high RPM. Regularly check alternator cleanliness and ventilation to ensure long, trouble-free operation.
