My parents recently gave me their older boat. Dad didn't keep up on
maintenance with it and I'm trying to figure it all out. Is there a cb
or other protection that would stop the engine from starting or power
tilt from working? It works for a second then stops and nothing.
I have power under the center console but it's not going thru 3
switches. Can switches die like that? Mom said boat was turn key.
Switches seem fine but power not going thru them, unless there is a
missing ground that I'm not seeing.

I've got power going thru the nav lights but the nav lights are working.
I get power to the anchor light connection, but the anchor light isn't
coming on. Phooey!

There is a silver round thing under the dash called Delta-Larm. Any idea
what it is?
Thanks for any help.
