Marine Alternators

Just as in cars and trucks, marine alternators provide electricity that is generated and collected to use as an alternative means of providing electric current. Inside an alternator is a coil of wire that is rotated in a magnetic field, and this action generates the current. Onboard a ship or boat, marine alternators may be attached to the engine, or the propeller shaft. Alternators have two main parts, a stator and a rotor, one remains stationary and the other rotates as part of the alternator’s energy collection system.

How to Troubleshoot Marine Alternators

There is a simple test to see if your alternator is working. Using the panel voltmeter, the reading should be 12 volts with the ignition on, but without the engine running. If you do not read a jump to 14 volts when you kick over the engine, alternator/regulator failure is usually the culprit. When you need a replacement boat alternator, come to Wholesale Marine.
