My two batteries are officially dead. That said, I need some recommendations based on the diagram below. <BR> <BR>It is setup where the amps, tower lights and ballast all run off batt 2. I would keep the switch set to batt 1 in all cases except emergencies. <BR> <BR>Should I have a starter battery for batt 1 and deep cycle for batt 2? <BR> <BR>Should an on-board charger be added for battery 2 and should I remove the isolator? <BR> <BR>thanks <BR> <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/700381.jpg" alt="Upload">
