Starting in June, Northern Lights is changing their DC Logic for the first time in over 40 years.  The affected generators include marine units from M673LD3 through M944T sizes – including commercial marine sets through the M40C3.  The first difference you will see is that the generators will be coming with a different plug.

The connector will change from the black, round connector (known as the “Merc plug”) to a gray, rectangular Deutsch DT plug.

Deutsch DT series connectors are rugged and weatherproof and are common to many transportation wiring systems.  Northern Lights DC Logic remains simple and easy to diagnose. The new relay logic will provide easier installation of advanced control panels being offered by the factory.  Below are links to the old wiring schematic versus the new wiring schematic.  A limited number of generators with the old DC wiring are still available. Contact Parts & Power in Tortola, or your nearest Caribbean dealer, for more information.
