I have a 2003 MS 400. This boat is new to me and am still learning what and where everything is. I was using the 120 volt outlet in the main salon, switchable by a breaker on the panel. Worked fine.
Yesterday I turned it on and no indicator light and no power. I also noticed that there were 3 other breakers that had no power. All on the 120 panel.
A quick review of the wiring diagram showed they all came from the second leg of the 220 breaker.
I turned off the shore power and removed the panel for a look. I can see the second leg power coming from each 3 part breaker going to several other circuits. When I trace the circuit in question, all 4 circuits are wired together. The last one has a black wired that runs into the wire loom. No where else do any of these connect to a breaker on the power side. The other items on the 2nd leg are wired to the second leg eventually and work.
Leg 1 uses red wire, Leg 2 uses black wire and #3 leg (middle leg on each breaker) is the neutral and is white.
I turned on the shore power with the panel removed and tested power at all 3 legs. 120 from the middle (neutral) to leg 1 and leg 2. 220 across leg 1 and 2.
I also went to each 120 outlet to confirm the GFI had not tripped, although this would not cause my issue.
Again I can see a wire running from the breakers that don't work into the loom on the feed side.
I'm wondering where that wire goes and did I trip something. I've been doing regular maintenance and as mentioned this circuit DID work a couple of days ago.
One idea I had was to just run a wire from the 2nd leg to one of the non-working circuits. I'd have a marine electrician take a look and confirm my suggestion would work, but I'd like to figure this out. Any suggestions??
