280DA help

[355spider]

I have a couple problems that I need a dx for. Hope you guys can help. My outside speakers have stopped working. They put out a tiny amount of sound. You can barely hear them. Maybe one channel of the radio went out?
Also my starboard light is out but I tried a new bulb and no dice. Is there a fuse just for that light. None of my breakers appear to be tripped.
My trim tabs are also not working which makes me think they are on the same breaker. Is there a flip breaker for the trim tabs like the one for the windlass? Thanks guys.

What year 280DA ? I had a 1990 280DA....and under each switch on the dash .....there was a small push breaker for that circuit.....there was also a 12V breaker panel in the engine room.

Have you tested the "hot" side of the trim tab rocker switch ?

Your nav lights would all be on the same breaker. I doubt the lights and trim tabs would share a breaker. Clean the corrosion off the contacts for the light and try again. Is there fluid in the trim tab reservoir?

Yep got plenty of fluid in them and all connections look goo and clean.

Trace the light wire back and use a circuit tester on it. As noted in the VF thread, corrosion can wick up into a wire and destroy it inside the insulation. For the speakers, do you have a mute switch at the helm for the outside speakers? If so check it's position and wires as well.
