Balmar XT-Series Alternators Designed for Recreational Applications XT-Series Alternators from Balmar bring together the latest innovations in alternator design to deliver incredible charging power in a compact, Marine-friendly package. The XT-Series Alternator family features a state-of-the-art, braided stator wire design to generate exceptional output in the smallest possible area. The XT-Series produces slightly more power than our previous AT-Series 165A design and operates 5-10 degrees C cooler.In addition, we've added Balmar's Smart Ready internal regulator technology to provide an additional level of fault tolerance for cruising boaters.Available XT-Series mounting styles have also expanded to include the "Vortec" 9Si design found on many GM gasoline engines. XT-Series Alternators may require a Tachometer Signal Stabilizer (Part No. 15-TSS) if your current tach is not adjustable.XT-Series Alternators should only be used in Dual Vee or Multi-Groove Serpentine belt configurations. Balmar's growing range of AltMount Serpentine Pulley Conversion Kits support all XT-Series Alternators.
