The \u003cstrong\u003e60 Series 100A 12V Alternator\u003c\/strong\u003e is built to deliver high-amperage charging performance where standard automotive units fall short. Featuring a \u003cstrong\u003e3.15in (approx. 80mm) Hitachi-style dual-foot saddle mount\u003c\/strong\u003e and an \u003cstrong\u003eisolated ground configuration\u003c\/strong\u003e, this high-output alternator provides reliable energy generation for recreational marine and off-grid applications.\u003c\/p\u003e\u003ch3\u003eDesigned for Recreational Applications\u003c\/h3\u003e\u003cp\u003eStandard automotive alternators are designed primarily to maintain a starting battery and handle intermittent loads. The 60 Series is part of Balmar's 6-Series, which delivers high output in a compact, small-case package with dual fan cooling and a high airflow frame. Balmar designs its 6-Series alternators for recreational applications and describes them as ideal for modest charging upgrades. Its Smart Ready internal regulator may be sufficient where battery loads are relatively small and the engine runs frequently. For larger deep-cycle battery banks, or where the engine runs less often (as on most sailing vessels), pair it with a Balmar ARS-5 or Max Charge multi-stage regulator.\u003c\/p\u003e\u003ch3\u003eIsolated Ground Protection for Marine Vessels\u003c\/h3\u003e\u003cp\u003eIn marine environments, electrical integrity is critical. This unit features an \u003cstrong\u003eIsolated Ground (IsoGrd)\u003c\/strong\u003e design, meaning the alternator's internal ground circuit is completely separated from its outer aluminium casing. Using an isolated ground alternator prevents stray DC currents from travelling through the engine block and hull, effectively mitigating the risk of galvanic corrosion, electrolysis, and damage to sensitive onboard electronics.\u003c\/p\u003e\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e100A Output at 12V:\u003c\/strong\u003e Delivers substantial charging current to rapidly replenish depleted auxiliary and house battery banks, reducing engine runtime.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3.15in (Approx. 80mm) Saddle Mount:\u003c\/strong\u003e Hitachi-style dual-foot mount, typical for Yanmar, Westerbeke, Lehman and Perkins-Sabre engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolated Ground Architecture:\u003c\/strong\u003e Dedicated positive and negative terminal posts prevent stray current corrosion in metal-hulled vessels and composite marine installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomisable Drive Interface:\u003c\/strong\u003e Supplied bare (without a pulley) to suit 17mm bore pulleys, allowing you to configure the exact belt profile required for your specific engine setup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eImportant Exclusion: Pulley Sold Separately\u003c\/h3\u003e\u003cp\u003eTo ensure seamless integration with various engine belt configurations, \u003cstrong\u003ethis alternator is supplied without a pulley\u003c\/strong\u003e.
