110v plugs not working

March 24, 2021, 07:15:21 pm

Some electrical outlets on the drivers side of coach forward from microwave, including bay at sewer water connections, not working.
Does not matter if  generator, shore power or inverter.
 A few items I have checked are:
GFI Not tripped, voltage is passing thru all conductors
No breakers on inverter tripped
No breakers on electrical panels not tripped, check voltage on all circuits (breakers)
ATS is working, checked voltage
Any ideas?

99 U270 4000 CAI

Update :4/26
Cleaned contacts on ATS, Verify voltage on all connections.
Reset Inverter.
Rewired suspected circuit from sub panel which is by inverter to main panel.
Determined all 3 runs on drivers side of coach have power under bed, thru floor, under lavatory, and in cabinet behind toilet.
Seems to be break further forward.. try again tomorrow

Thanks everyone for info.

Recheck GFI, especially the one in the bath. Ours has brown buttons and I didn't see it until I had a lot of light and good glasses. It knocked out a lot of outlets. You can also use a tone generator or outlet finder to see where each run goes. HD has a good one from Klein Tools. The Home Depot Logo

Also forgot to mention.
Removed GFI and tied both runs straight through.
Reset all breakers.
Replaced breaker for this circuit.

I have a similar issue, where many outlets do not have power in the kitchen, lounging and bedroom areas. The GFI in the bath and the one under the sink cabinet works however. Am running off the generator and reset all the breakers.

If you have power on both sides of the second transfer switch (it's under the top one which is the main shore power/generator ATS) then that provides power to the inverter.  The inverter then passes power through to power the individual outlets.
So either the second ATS or your inverter might be the problem.

Danny,

You may have one of the hardest things to find.  With all that you have done you may have a bad receptacle that feed the string that follows. They are thrifty made and are used in place of junction boxes. I know that isn't much help but have seen a failure like this give the same symptoms.

I think Mike has it, an outlet isn't feeding through. Turn on something that should be on, and then plug in a 3 prong plug in each other socket that is dead and wiggle it around and back and forth, if you find where you get a response - replace that outlet.

Replaced gfi today, and pull every outlet that was not working, checked pass thru. Has not helped.

Danny,

Did you check the hidden ones like under the bathroom vanity (our coach has 2 hid in this area)?  Could be one under the kitchen sink.  I have seen one under the fridge in that little cabinet.  So look around for these hidden ones.  These will be turned with the back looking out.  You will have to remove 2 screws to get to the front side so they can be disassembled and checked.

On a prior house I once had my main breaker fail. One leg of the panel had no power. This meant all breakers on the left or on the right. Unlucky for me it ended up that the kitchen refrigerator and a freezer in the garage were both on that leg and we were gone for a multi day weekend. You might check for this.

I have attached my 120v diagrams. Perhaps when looking at your diagrams you will see a relationship between all the outlets that are have no power.

Update: After doing a survey of outlets it appears the nonworking ones are on the "Duplex" circuit. What is the duplex circuit, the second leg? Additionally, they show approximately 96v open circuit. However drops to approximately 60v loaded with a T5 undercabinet type flourescent light fixture. It appears this is a loose coupling action from the "direct" leg. Any insights and/or suggestions?

So I have a 99 coach with "electrically speaking" drivers side washer combo outlet -> wetbay outlet -> private potty -> microwave outlet... do you have a 100vac washer outlet? My washer elec outlet is located under the cabinet behind potty under the lowest shelf mounted on the plywood floor.  If so, have you checked that receptacle for a loose connection? - apparently you have power in bathroom but thought I would mention it. - just a thought

If you have taken apart the ones not working  it could be one that is working but not passing the power through

You could buy a toner  from home depot or Lowe's  you will then be able to trace out the circuit
