   • Bearings are pressed into place, and the pulley is attached to the rotor shaft.
   • Critical connections are soldered or crimped using automated systems to ensure reliability.
4. Testing and Validation:
   • Functional Testing: Each alternator undergoes comprehensive testing on a dynamometer to verify output voltage, current at various RPMs (idle to maximum), and regulation stability.
   • Environmental Testing: Sample units are subjected to vibration, thermal cycling (-40°C to +150°C), salt spray, and humidity tests to simulate extreme operational conditions.
   • Compliance: All products are manufactured to stringent international standards such as ISO 9001 for quality management and relevant SAE (Society of Automotive Engineers) and ANSI (American National Standards Institute) standards for performance and design. For example, ISO 16750 for road vehicle environmental conditions, and SAE J180 for alternator output curves.
   • Life Cycle Testing: Extended operational tests are performed on a representative sample to validate the service life expectancy, often exceeding 10,000 hours.
5. Final Inspection and Packaging:
   • Visual inspection for any cosmetic or assembly defects.
   • Protective packaging to prevent damage during transit.
