Alternator Testing Equipment

ALT-72 Laboratory Performance Testing

The ALT-72 is designed to provide manufacturers with a detailed test of the alternator’s performance and endurance under varied temperatures and thermal conditions. Custom test procedures are easily configured to vary the temperature, alternator speed, and other test parameters for accurate alternator diagnosis undetected under normal testing conditions.
