I was out on the lake using my air pump plugged into the lighter port and it quit working along with my radio and bilge. I hit the reset and they didn't kick back on. I looked at the 4a inline fuse by the battery and it looked old but not blown. I went to replace it any ways just to be sure and the new fuse seems loose in the glass fuse holder like it's not making good contact. Was planning on replacing the inline fuse holder but I guess my question is, is that fuse likely the problem or is there something else I should be looking at for the issues I'm having?
