OK, Here is the extra power panel and the challenge to install it is that the faceplate is not uch bigger than the rings that tighten underneath leaving not much room for cutting error. It is really nice having a battery voltage and percentage left gauge at your fingertips. Just connected it to the top of the 50 amp breaker for power and the top of the light switch for ground and the USB, 12volt cigarette and on/off switch are daisy chained.
Also new inline 50amp fuse at the battery. The one it came with I had to constantly be tweaking the wires around for it to connect and it looks like the same one you can get at the Sun Dolphin website for 16 dollars. This one is easy to install and also has a push button quick disconnect so I will not install the battery switch until later as I only have one battery for now.
Just have left to install the rear trolling motor plug under rear deck outside battery box (got it at napa auto parts after searching he part number) once I get some more wire that big and to move the fish finder to the back but I'm still debating on that as space will be tight.
I was also wondering why is there an inline fuse at the battery when the power panel has circuit breakers but from looking at it the 50 amp breaker only protects the front trolling motor plug and the 5 amp protects the aerator. There are other inline fuses for the lights buried in the hull, which led to my initial problem of a disconnect.
