The New 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 the previous AT-Series 165A design and operates 5-10C cooler. In addition, Balmar has added Balmar's Smart Ready0 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, if your current Tachometer is not adjustable. This has Hitachi-Style Mounting; Typical for Yanmar, Westerbeke, Lehman & Perkins-Sabre Engines.

This is an XT series Alternator, 170A, 12V, with a 3.15" Saddle Mount (Dual Foot), with the K6 Serpentine Pulley, with an Isolated Ground.

*NOTE* - This is the XT Series Alternator which ends in IG. IG stands for Isolated Ground Termination, meaning the ground is isolated from the case of of the alternator. This type of grounding should produce less electrical noise on the system.
