Balmar Alternator 100 AMP Kit 12V 3.15" Dual Foot Saddle Dual Pulley Regulator & Temp Sensor

The Balmar Alternator 100 AMP Kit 12V with 3.15" Dual Foot Saddle and Dual Pulley is a comprehensive marine charging system engineered for high-output electrical demands on vessels equipped with Yanmar, Westerbeke, Lehman, or Perkins-Sabre engines. This complete alternator kit delivers 100 amperes at 12 volts, providing the sustained charging capacity required for extended offshore operations, liveaboard systems, and vessels running multiple electrical loads simultaneously.

The kit includes a 60-100-DV alternator with isolated ground design, MC-618 regulator, temperature sensors, and complete mounting hardware. The dual foot saddle mount and dual deep vee pulley configuration ensure secure engine integration and optimized belt tension management. The isolated ground system prevents ground loop noise and voltage regulation issues common in marine electrical architectures. The MC-618 regulator maintains precise voltage output across varying engine speeds and electrical loads, while integrated temperature sensors protect against thermal overage in high-demand conditions typical of extended cruising or auxiliary power scenarios.

This Balmar 100-amp alternator kit is the direct replacement for the legacy 60-YP-MC-100-SR-KIT and applies to cruising sailboats, fishing vessels, expedition yachts, and trawlers relying on Hitachi-style engine mounts. The 100-ampere output suits applications where battery banks exceed 200 amp-hours or where multiple systems—refrigeration, watermakers, radar, autopilot—operate concurrently. Operators managing remote anchorages or long passages benefit from the charging headroom this system provides, reducing engine runtime required to restore depleted battery reserves. The regulator's temperature compensation ensures output stability in tropical or high-load environments.
