When I was boating last weekend my stereo on my boat just stopped all the sudden. When I got home I thought it was just a fuse so I check the fuse on the back of the radio and that was fine and then under the steering wheel is the fuse pannel which has a line of fuses all over with a rubber protective casing so not being able to get to the fuse from the front I took the whole panel off and from behind it, it looks like each is a cartridge fuse but when I pulled it out and checked it with my voltage meeter it gave me a reading, so that has to be good too. What else can it be anyone have this problem before? Thanks
