Marine Alternators for Sale
An alternator is an electrical generator that converts mechanical energy into electricity VIA alternating current. The first alternator was invented in 1890 and by the 1960s, they found their way into cars and trucks, supplanting the old DC dynamo generator. Marine alternators are constructed in a similar fashion to the automotive grade alternator, with the notable exception of marine alternators being shielded from moisture and salt spray. Not only is water bad for electrical components, the salt in the ocean air and seawater is highly corrosive to metal, such as the copper innards of an alternator. Marine alternators also differ from automotive alternators by incorporating such marine-specific features including spark screens, double insulation, corrosion-resistant metals and coatings, battery-sensing regulators, and durable enclosed compartments.
