I have the docs you sent. They came with the counter. My question is on a 310, where do I connect the + terminal lead on the counter that is connected directly to a battery and doesn't go thru the battery select switch on the panel? I guess I could connect it to a battery terminal on the battery select switch.
P.S> For Bob. A boat at my marina took a lightening strike. It killed one battery and the fuel gauge and put a small hole in a through-hull. (Lightening is a strange thing) They only go to their boat on weekends. Before leaving their slip, they noticed a large number of bilge runs in a 24 hour period and in the week long period beyond the baseline numbers. They knew something additional was wrong due to the strike.
