Took the 09 Puma to Sears as I suspected I had a battery issue. Told them I wanted them isolated and checked, after doing this they told me one needed to be replaced. After replacing it I took the boat home and placed it on charge. The following day, NOCO 4 bank shows 4 green I head for the lake. I drop the trolling motor and theres barely enough juice to turn the prop. Unfortunately Im on the road and cant trouble shoot this myself but I suspect Sears didnt reconnect them properlyor I have a charger issue. I want to know how the 3 trolling motor batteries are supposed to be connected so I can have this checked first. The batteries, if it matters, are group 27 maintenance free. Any help would be appreciated.
