I bought a used 1999 Fisher Deck Boat with a 4.3L engine and the wiring is really strange. The previous owner may have made changes that are incorrect. Here is the system and questions. There are three batteries. The two trolling motor batteries do not have a common ground with the starting battery. There is a Dual Pro SE charging system wired to one trolling motor battery and the starting battery. The alternator goes to the starting battery and the + side of that battery is wire through #10 wire to the "A" terminal of a Sure Power 702 Isolator. The other two terminals of the isolator go to the two trolling motors. The base of the isolator is screwed to wood so there is no ground. The two trolling motor batteries are wired in series with a contact at the series connection so that the trolling motor can run on 12 or 24 volts. The trolling motor is a 12/24 volt Motor Guide.
Questions:
1. Will the Dual Pro SE charge both trolling motor batteries?
2. Is the isolator wired wrong? I would think the way it is wired that it would draw down the starting motor battery.
3. Does the base of the isolator need to be grounded?
4. Can the isolator charge both trolling motors?
