I posted in another thread earlier today that my DC main power was running directly from the battery to the breaker and then to the DC panel. So when I had both of my battery switches completely in the off position my 12 volt cabin accessories still work. Many pointed out it didn’t seem right and could be a safety issue which I agreed. This boat has a Sure Power 2703 Battery Isolator. So I started looking closer and found this...
Am I looking at this wrong or would this have the dc power bypassing the battery on/off switch?
