I have a 1997 198SE with one battery. I have tried to install BlueSea's "add a battery" system with the charging relay. I cant seem to find where the power to the house panel is coming from. I have looked at the the wiring diagrams on here but they are not very helpful in determining where the power to the accessories is coming from. Currently there is only one line going from the battery to the starter, so the power to the other accessories has to be fed from the starter. I have attached the wiring diagram from the box, it seems simple, but i cannot find the line I need to connect that runs to the house panel.

In lieu of finding where the line comes from the back, Can I disconnect the current power line from the battery to the ignition switch and run a new line to the the house battery and connect to the battery? is there anything being powered from the ignition switch that would, the only things that work while the key is off is the trim and the bilge pump. which do not

any help is greatly appreciated.

yes you are right. look at the panel and you will have one wire energising the panel. get a color and try to find it in the back.that wire is probably fed through the key switch on lug.my 235zc has a separate #10 gauge wire to the back that has a eye connector i put under the thumb screw on the battery
but this is just a charger. you can isolate the two batteries with a manual isolation switch.
