We launched the boat from storage last week and the port motor needed the emergency start parallel to start. I had the boat on the charger for a few days at the dock, and when I tried again I experienced the same thing. Starboard motor, house 12v systems all seem fine. I figured the port must be the stand alone motor and decided to replace the battery. I have a 3 battery system without a generator. Two are wired inline, one by itself. I disconnected the stand alone battery and toggled the ignitions to see which motor was isolated. To my surprise, both motors fuel pumps turned on and cranked. I did not have a load tester on me of course, and changed that battery anyway. When I got home, I tested the battery I pulled out and it tested fine. I have the other two batteries on order (they only had one in stock) so I'll be starting fresh but I'm very concerned that I don't have a house / motor batteries and an isolated motor battery.the wiring is all original, as are the battery solenoids and charger. This doesn't feel right to me. Am I wrong?
