I have owned my 1984 Catalina 27 for six years. I am having an issue with the battery charging system. It is a Sea Ranger Marine Battery Charger 1500 Automatic.I have no manual or have any info about this unit. Last season I purchased two newDeep Cycle batteries for the boat. This season, I am having difficulty charging thebatteries, or at least that is what I think. I am plugged into shore power, have the charger plugged into the GFI outlet in the galley and have had the battery bankin the cabin in the "Off" position. This morning, I tried to start the boat on #2battery & got nothing but "clicking" with no turnover, did the same on #1 battery with the same result. When I put the battery bank on "All" it turns right over. In all the time I have had this boat - I don't recall having to put the battery bankon "All" position to start the boat. I am thinking the batteries are not "charging" when I think they are...maybe it is not even the batteries. Could it be the enginestarter, cellinoid or something else?? Does anyone have any suggestions for me.Thanks in advance, Jim
