AC outlets not working

We spent the night plugged into shore power last night and non of the AC outlets worked. What are the troubleshooting steps I should take to address this? Thanks a lot.

Do or do not... There is no try.

Re: AC outlets not working

Pretty wide question, but here's some thoughts on the easy stuff:
1. Start with the shore power cord. The connectors are a weak point. Make sure they are fully seated. The most common ones require a little twist. I'm assuming in this case you don't have power at the panel in the boat.
2. If you have power at the panel, there is probably an volt meter or indicator showing this. If that's OK.
3. The next suspect is GFI outlets that have popped. Check these. Depending on how it's wired, a GFI popping on one outlet might effect the others.

I've skipped a number of other things that could have failed like the shore power cord itself, the stuff on the marina end, the circuit breakers, and wiring in between....the idea is start at the source and work towards the outlet. If you're not sure about working with 110 volts, hire someone to chase this other stuff or at least get someone to help you who is. Bad stuff can happen to you and your boat with 110....good luck

Re: AC outlets not working

Voltmeter.

Make sure the outlet switch on the AC panel is on.

Check at the power pylon. Check at the boat end of the cord. Check at the back of the power receptacle. Check at the inlet to the AC panel. Check at the inlet to the battery charger. Check the outlet of the AC breakers for the outlets. Has GFCI tripped anywhere?

All checks are on an electrically hot system so if you aren't comfortable with that get qualified help.

Re: AC outlets not working

Sometimes the boat before you blew a breaker in the dock pylon, Then they switch plugs and blew that one too. Then they moved on ,not knowing how to go click click. Start there and test with a multimeter back to boat .Knowing your system can usually point to problem at a glance before you have to go out in the rain.

Re: AC outlets not working

My money is either a bad circuit breaker on your panel or more likely, a tripped GFCI outlet. FYI, 2 friends, 2 different boats, both had non working outlets. After some searching we found hidden GFCI outlets on both boats that neither owner was aware they were even there. Pressed the button and all of a sudden, all outlets were now working. It was a miracle.

Re: AC outlets not working

... another odd one, on my boat there is a circuit breaker in the aft locker. The shore power goes into a box, the breaker, then into the boat distribution panel.

That's actually a good thing.

Re: AC outlets not working

What have you checked? Is this your boat, a new boat, a rented boat? Above lists are pretty complete (I was once stymied by the breaker in the aft locker I didn't know about too).

It's not inconceivable that the outlets (some or all) are powered only by an invertor, rather than shorepower.

Re: AC outlets not working

Obviously you have discontinuous circuit...

1. Is the shore power breaker working and ON
2. Are the shore power cable plugs well seated?
3. Are all connections made up properly and not corroded?
4. Is there a main breaker inside the boat? (there should be) Are the connections made up properly and no corrosion?
5. Is there a distribution panel (circuit breakers)? Are the connections made up properly and no corrosion?
9. Are all the outlet connections made up properly and no corrosion?

Did you notice any melted plastic at outlets?

You should check for polarity and shorted wires.

Is there heat at any devices or wire?
