I have a 23 year old boat. It used to have a trolling motor on it that pluged into a control board on the front of my boat.. The board displayed battery voltage, and gave me the option to toggle between two batteries... I have since replaced the trolling motor.. And now the switches on this board have burnt out.. My question.. I am going to build a new board.. What kind of goodies are good to have? The voltage readout seems important.. As is the switch for switching between two batteries.. Is there anything else that anyone can think of that might be nice incorporated into this control board?
