Thx Brucepic, I am learning a lot. That makes sense with the battery tab. I am sure that with the exiter wire off , this Volvo does no charging. Thats because I ran out on juice with it off. And I drove it all over the place. With my exciter switch open. No charging and if I get in a pinch, I can flick it on and not be stranded. You said my two battery rig was not ideal and my plan is to leave the 2nd battery in connected and try running on the marine battery 100 percent.. Sc
