Good evening, Boat Owners!

I have an '07 SunSport 22V that is having some sort of wiring issue. I want to start tracing the wiring out, but wanted to see if anyone has access to the wiring schematics for this boat, or one of similar nature.

I noticed that my radio wasn't working when I turned everything on after de-winterizing the boat. Started checking wiring and when the Stereo rocker switch is ON, the dash lights up about half way. After checking with the multimeter, I found that the power is getting drug down to about 5 volts DC a the radio.

I started with the rocker switch itself, but that's not the problem. While doing this into the night hours, I also noticed that when ANY of the rocker switches are turned on, the dash lights up! Dim, but still illuminating. Only when I turn the Nav light switch ON does it light up fully.

This is all telling me that there is a shorted hot somewhere in the fuse block or wiring harness. A "map" of where I need to start and end would be super helpful!

Thanks in advance for any assistance!!!
