JB, I have done a lot of research for my 36' SS. It has 4 12 volt systems and here is what I am going to do.
1. Start battery for each engine 2. Start Battery (smaller) for the generator 3. House batteries (not sure what batteries yet, will be determined by remaining budget at end of re-fit. The two main engines will be seperated from eachother with cables from thier respective batteries. There will be a battery combiner switch between the batteries. This switch will be in the engine compartment. The supply for the switch will run to a combiner switch at the helm that will allow you to connect the engine(s) to the house circuit. If on 1 or 2 then either the port or starboard engine will be connected to the house batteries for emergency starting purposes. Normally with everything working properly the engines will be left in parallel all the time and the switch turned off when not in use. There will also be plain on / off switches for each engine battery to turn them off during storage. On the house circuit there will be an automatic charging relay that will automaticlly connect the engine(s) to the house batteries to charge them. This unit has starting isolation so that when the engines are starting the relay will not connect the two banks. The house circuit will also have the ability to be charged froman on-board battery charger. The generator 12V circuit will be completely isolated from the rest of the boat. I will have jumper cables for emergency puroses though. In normal operation you will get to the boat and turn on the two battery switches for the main engine batteries, switch the 120V system from shore to gen, and prepare to leave... If there is a problem with the main engine starting batteries there will be a very fast option to start from the house circuit. For more information you can look on Blue Sea Systems website. they have some great information on boat wiring. Of course they are wanting you to buy thier stuff. I do reccomed thier products as I am very impressed with the way they are engineered. I will be posting my boats wiring diagrams soon. I am still working on them. I am re-engineering the entire system. hope this helps, Victor --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "UnifliteWorld" group.
