FWIW. In my 2000 Sea Ray 185, the thin red fused (10amp) wire from the
battery is for the amfm radio memory. I believe it does create a small
drain because the radio needs some juice for the memory.

Hmmm, standard practice is for the thin yellow wire to be the unswitched
12V+ source for memory presets, and the red wire to be the switched 12V+
source that actually powers the unit.
