I am a new owner of a 2014 23 FB FC.
I am an Electrician and Engineer with 40 yrs. experiance ( 58YO).
One of the first things I've changed in the Electrical is the ATO fuses.
I've changed them to Indicator ATO fuses, it is a really cool idea.
The fuses have a small LED across the fuseable element. So if the fuse
blows, it lights up! Here is a link to the product that is available at any good auto parts store. But much cheaper at the link.
ATO Smart Glow Fuses
Next will be a better voltage monitor then a portable Solar set up.
