In a mixing bowl, sift together the flour, salt, baking soda, baking powder, and cinnamon. Mix the beaten eggs, oil, and sugar and add to the flour mixture. Stir in the grated zucchini, coconut, nuts, and cherries. Pour the batter into the loaf pans and bake for 1 hour; a toothpick inserted into the center of the loaf should come out clean. Cool for 10 minutes before removing the loaves from the pans. Turn the breads out onto wire racks to cool completely.
