[honest mark]

I CLEANED OFF AND WIRE BRUSHED ALMOST ALL OF THE CONNECTIONS AND STILL HAVE A PROBLEM STARTING THE PORT BATTERY WITHOUT THE HELP OF THE BATTERY INTERCONNECT SWITCH UNDER THE STAIRS , WITH THAT BEING SAID, UNTILL I CAN LOCATE THE PROBLEM AM I HURTING THE BATTERIES/CHARGER OR ANYTHING ELSE IF I USE THAT INTERCONNECT TO START THE BOAT EACH TIME?? AFTER THE BOAT STARTS I TURN THE SWITCH OFF?? I ALSO START UP THE GENERATOR FIRST, THEN THE BOAT, IS THAT THE CORRECT SEQUENCE YOU GUYS USE, OR WOULD YOU START BOAT WHILE ITS STILL HOOKED UP TO SHORE POWER, THEN START GENERATOR?? THANK YOU GUYS FOR HELPING.
