I just got this 1992 Sea Ray 270. It's a single engine 7.4 I got some things powered back up but can't get others. The fuses under the console are good and checked the breakers in the engine compartment to. If any on has the whole wiring diagram I could see it would help a lot. I am currently trying to get the bilge pumps working. I checked the switch it is ok. I am not getting power to the breaker in the engine area. I unhooked both wires and tested and no power the other breakers have power so I was wonder if there is a fuse any wear else.
