I am rewiring my 1978 h30. Within the quarter birth there is a compartment for access to the electrical panel and a place for a battery (engine/start). It takes up about the first 18 inches of the quarter birth, right at the nav station. To the rear of that is a mystery. I was thinking of cutting it open and using the space for my power inverter. It seems that it would be the perfect place. Does anyone know what I will find when I open it up and more importantly does anyone know why I should not open up this compartment or install my inverter in there. Yes I would do what is neccessary to ventilate it. All thoughts appreciated.
