A Tip From Marquis!
dedicating a 12-volt battery to the generator provides an important safety feature. A dedicated battery enables you to
start the generator regardless of the condition of the propulsion engine batteries. If the batteries become discharged to
the point where they are unable to start an engine: start the generator, then turn on the engine battery chargers. when
the engine batteries are recharged to an adequate level, you can start the propulsion engines.
