Dinghy Wire gauge for battery terminal?
I have had to put new lugs on my dinghy battery whilst away on Pender Island. The local marine store was hopeless, and the hardware store only has car size copper lugs which are too large, but have worked in a pinch as a temporary fix. Does anyone know what size lugs I should order and battery terminal ring size for this? It's a 20hp Tohatsu engine fitted with a 12v battery, and the copper wire diameter looks just over 4mm inside the insulation. See attached pics. Any suggestion which size lugs and ring size I should order? Luckily I have a good crimper that came with the boat. I was thinking they look like 6 AWG?
Any tips gratefully received!
