Failure of AC outlet in cal cruising 46 pilothouse

[edwmama]

AC outlets suddenly not working
Hello fellow sailors
I have one of the original Cal Cruising 46
While out in catalina island during Easter weekend I had
My 3 kilowatt genset running so I can charge the batteries and use the microwave. I had just used the microwave in the pilothouse when a crew had decided To Warm his coffee. To my surprise the GFCI protected
Outlet had stopped working and the Microwave would not even run. Despite pressing the reset button
On the GCFI reset button and flicking the main AC circuit breaker
Over the master control panel. Then I discovered that all my AC outlets went dead!

After returning to Marina del rey CA I connected the shore power cord and I could only get one of the outlets to work. The one in the aft head

I have professionally installed an MS 3000 Xantrex charger/inverter
2 years ago which is required to run most of the AC outlets
I have never had any problems with AC outlets

My question is. How do I diagnose this problem. Is this serious

Could it have been caused by a defective microwave that perhaps
Requires ampure sinewave electrical soured which I doubt
It my MACE 5501 genset provides I have never tinkered with my AC plugs before

How do I dignose and fix this problem?
I am an avid DIY

Don't think I'll be firing up my email app for the reply but...

First unplug everything from the AC circuit. If the AC outlets protected by the GFI still won't work, just replace the GFI. It is cheap and easy and likely that is the problem. If that doesn't work, then it is a matter of pulling out your electrical tester and start with your shore power plug and test everything.

My guess is the GFI however.

Are you sure that the AC outlet in the aft head wasn't working when you were runng ac off the gen set? The GFI's are often installed at the fiist outlet so that all down stream outlets are also protected. Maybe the aft head outlet is actually the first in the circuit. I'm kind of with Dave that the GFI is the prim suspect. I think (hope) they are designed to fail such that if the GFI fails the outlet will not work. Get one of those coded three light plug in outlet testers from Home Depot or any hardware store. That should help you zero in on what is going on.
