I am the original owner of IP35 # 175 and have a 120v problem I cannot figure out.  One day I noticed that my port outlets were not working - none of them.  The starboard outlets and all other AC systems were fine.  I checked behind the panel and noted no corrosion or loose wiring.  Power is going to the port outlet breaker and out of it when engaged. It appears to be working fine.  I pulled the port outlet closest to the panel and there was no power to the wires.  Again no corrosion or loose wiring.  I am not nearly as familiar with 120 volt systems or wiring as I am with 12 volt, so I really don't how to trouble shoot this issue any further.  As far as I know there is not a GFI on the port outlets.  I have one in the galley only.  I guess my question is are the outlets wired in such a way that a short or loose wire in one will result in loss of power to them all?  If so, I can pull each one and inspect it.  I have a hard time believing that there is a break in connection between the port outlet breaker and the first outlet,  and it is nearly impossible to follow individual wires back there anyway.  Any help is most appreciated.  BTW - nice site and I intend to become more active as time goes on.  I love my IP!  Glenn Parker
