Rewiring my Catalina 25
First off.. I know nothing about electrical systems.
Right now I have 1 marina battery that is being fed by a Coleman Solar Panel. Which runs the cabin lights, running lights, and a 12v cigarette plug.
I would like to add a gauge to see what my battery's juice level is, and I want to know what the load is currently.
What gauges should I buy and how would they work?
