12VDC fuse
Bob, there is a fuse (3amp I think) that is an in-line fuse on the 12VDC on the panel.If you open the panel (two screws at top), the panel hinges down, you will see a yellow (on my boat) inline fuse holder.Open it up, replace the fuse and you should be good to go.The area by the batteries is only a cover for the three way switch and windlass power switch (if you have one).Regards.BruceNeon Moon
