Dual diode assemblies, each with an array of 10 diodes, for a total of 20 diodes. Redundant capacity is designed in - if individual diodes fail, load is shifted to remaining functional diodes Straightforward design makes it an easy retro-fit in almost any charger with a "positive base" rectifier - those chargers with the positive DC lead/clamp assembly connected to the rectifier heat sink plate Full-wave rectification Includes Resistor Kit - for chargers manufactured by Associated Eqpt and equipped with "Stop/Go Lite" polarity protection technology (polarity indicator in the clamp). If your charger does not have this feature, do not install the resistor Equipped with center-mounted, insulated mounting bolt - for transformer mount on older Associated chargers, or direct mount in retro-fit applications with Rectifier Mounting Bracket Kit Our Heaviest-Duty Positive-Base Rectifier. Designed for use in chargers with continuous-duty output ratings up to 100 Amps, and "Boost" ratings up to 600 Amps. This rectifier is a direct replacement for Associated P/N 610100, used in Associated charger models 6001, 6002, 6002A, 6002B, 6003, 6006, 6008, 6009, 6009A, 6014, 6027B, 6065, NAPA 85-800, MATCO MC600, and SNAP-ON models YA165A, YA166B, YA167A, YA167B, YA168A, YA268, and others. Robust capacity makes this the perfect replacement rectifier for a wide variety of high-output battery chargers, especially those with high "boost" ratings.
