The company’s line of heavy-duty alternators is engineered for Class 1 to Class 8 trucks and construction equipment.
Millions of units have been installed and tested to OEM specifications, and include premium-brand Transpo electronics, as well as premium-grade WBD bearings. Alternators undergo thorough testing of output current at idle and full-load rpm. Additionally, validation testing for all products includes endurance, humidity, power thermal cycling, vibration, salt spray, and thermal shock. New alternators result in warranty rate reduction through extended field life of new units, WAI says. Computerized test sheets are included in every box.
