Yellow wire for stereo not getting power

[MichaelTG]

Okay this one is going to be a hard one but all the advice I have received from here has been so great I figured I would ask! So I had my 1994 sundancer 270 out this weekend and was listening to the radio and cruising when all of a sudden it just dies. What I mean by this is the stereo unit completely lost power. After pulling it out and using a meter to check voltage I have discovered that the red wire is getting the proper power but the yellow isn’t getting any! I have checked the fuses and even replaced them just in case and still nothing. I tested voltage before the fuses as well and still nothing. My question is where can I find the other end of this yellow wire? I have tried to find wiring diagrams for my boat but I think I will have better luck winning the lottery! I am assuming this wire connects to a terminal somewhere? I know it if the constant so it obviously goes straight to the battery but I can’t figure out where exactly that yellow wire connects before hitting the battery.

We would have to now more about your system and all the components to really diagnose, but the yellow wire typically is always hot for stereo memory back when that was a thing.

Edit: from the 1994 Sport Boat manual. Possibly some fuses in the bilge next to the batteries.

I will check that out! I have hooked both the yellow and red to the red wire and the radio works so I know for a fact that it is the yellow coming from the battery that is bad.

Should look like the one of the fuse holders shown in post # 10

this is the only fuse I can find within the vicinity of the battery which is to the left of the breaker box.

That would make sense. Bilge pumps are usually on a Hot bus, wired directly to the battery.

If that's not it, gour going to have to manually trace the wire back to its origin.

okay so I managed to trace that yellow wire and guess where it ended? The sump pump breaker! Why it was connected there I have no idea but after checking voltage my meter detected the breaker to be bad. I confirmed this by connecting the wires to and from the breaker together and sure enough the radio powered right up! So for anyone who has this year and model sea ray just a heads up that the hot lead for the radio is connected to the sump pump breaker.
