The Mastervolt 48420240 isolating kit is specifically designed for Alpha Compact alternators used with Volvo Penta engines. These alternators have their negative pole internally connected to the housing, which may cause grounding issues in isolated power systems. This 6-piece kit provides full electrical isolation by including two M8 and four M10 isolating bushings, allowing safe and isolated operation of the alternator. Compact, durable and essential for isolated installations, especially in marine and hybrid power systems.
