No house power only sofa functions nothing else

[THEBRAIN]

No house power only sofa functions nothing else an I have the red key turned on.
05plearsureway Lexor Chevy 3500
All fuses under front of sofa are fine, all breakers also under sofa are turned on.battery is charged to 12.2VDC an is at 90% capacity on amp hours.
I crawled under the van an felt around for the breaker inside the generater I think I flipped it not sure. Last time I reached inside the generater it was a much deeper reach than todays attempt.
depressed the GCI saftey buttom on the AC outlet in bathroom still no power.

I can press the generater start an she will turn over. just nothing else powers. battery connections look clean but I do see a tad bit of corrosion behind the smaller cables lug.

never had this no power issue.
Please advise on what to check

I am thinking you mean 120 volt. Do you have a volt meter and know how to use? If your plugged into shore power why are you concerned about the generator? Did you check power at the power plug in, the power panel inside the RV are the breakers all on?

 

[THEBRAIN]

not using shore power. this is a 12VDC issue an yes I know how to use my techtronic multi meter.
I should mention I accidently connected the house battery backwards (pleasureways color code is backwards where black is positive an white is negative who'd of thunk it but my fault for not correctly lableing completely I did wrape red tape on the black but left the white, then I remembered the canadian logic after the fact)

after I connected I jumped inside to test the sofa it was none functioning jumped back outside an observerd a bit of smoke from the negative side of battery this battery post was very hot to the touch.

so battery was connected backwards for less than 30 seconds. tested battery was still at 12.2VDC. will have battery tested this morning. comment if when stuff is connected backwards thats why we have fuses besides the little spade fuses on the 12VDC panel under sofa are there other fuses? thanks

Well if you would have posted 12 volt in the first post it would have helped. I doubt if you damaged your battery but get it charged the right way. I have no idea of where your fuses may be but I suspect you have blown a few. A GFI is in the AC 120 volt side.

Check and see if your converter has fuses.
Also see if you can locate the reverse polarity fuses.

the converter is shoved way up under the sofa it will be a reach but I'll check

the converter. where would these reverse polarity fuses be located? could this be a GM fuse. or is all house 12VDC RV stuff isolated from GM stuff? thanks DaveBad.
Gorge I never mentioned shore power in initial post.but did mention 12VDC thanks

OK these appear to be spade fuses thanks so much I'll check an report back
what about the smoke coming off battery when I connected backwards?could the battery itself be damaged?

Same PW, only mine is an 08/09 Chevy Lexor TS. You do know that even with the red key off, the sofa has power. Just an FYI. What about the breakers in the aisle just below the the passenger side ottoman? Your charge wizard would have nothing to do with your issue. All it does is convert the 110V and charge the house battery. If your sofa is working, then the battery is charged. I'm not sure why you mentioned the generator. That's 110V obviously, but just an FYI, if it runs, but the microwave digital display isn't on, then you need to reach in, left hand side and reset the breaker. I have a photo if need be.

 

[ChicagoTom]

One last thing, even though this has nothing to do with the wizard, if you ever need to get at it, you need to remove the sofa cushion, 2 screws, two bolts, if I remember. I will be replacing mine soon, just bought a used wizard exact replacement and I'll try to reply back on how to get at it.

Yes I'm aware of the sofa working w/ or w/out the red key turned on I believe it's the only device besides maybe the TV sys. that will power w/ red key off.
I have checked this breaker you speak of it's on pass. side aft of the furnace.

the black breaker had a lever can't remember it's position but I flipped it up then down or vise versa. Image was taken when 1st purchased van thus the dust.
haven't cranked up the generator in a long time I've read it needs to be cranked an run every 30 days. I mentioned the generater b/c I can turn it over from the control panel where the water pump on/off switch is.
yes I'd like to see this breaker behind the microwave is located.
or are you referring to the breaker deep inside generator?

IIRC I had to elevate the rear on ramps crawl under van reach way down inside the generator an feel around for the breaker. thanks Tom for any tips.

Not sure what you mean about the breaker behind the microwave. I would focus on the 12 volt system only. It's possible when you reversed polarity that you did something to the red key switch. You can jump the switch, I believe, I've never had to, but I know others on our FB group have mentioned it. Here's a photo of the generator, but again, that has nothing to do with your issue.
Are you sure you pressed that little tiny button for the converter in your photo?

 

[THEBRAIN]

I pressed up on this little button from underneth. did this w/ the red key on.still no house 12VDC power. from what I understand about a battery kill switch is when off it opens the circuit when on it closes.

I will take a close look at the battery kill switch also will jump the terminals will report back

 

[wmgeorge]

You said you had a Voltmeter and knew how to use it. Its very possible that a heavy overload could damage the contacts of that large circuit breaker, before it could trip, and it does look old. Just a old electrician speaking.

I'm not sure you're understanding the reset button. Look at your photo. The smaller reset-able breaker, right above the letters "30 Amp Power Converter". You can see the tiny black button. If that's popped, you need to press it back in. That would solve your problem

 

[wmgeorge]

I guess I am confused... with voltmeter why all the trial and error? The circuit breaker on the generator is for the AC output why are you resetting ? One leg of the voltmeter to ground will let you check the DC power. If you go across the breaker with a voltmeter, IF the breaker is closed you should get zero volts, if its open ( or bad) you will get a voltage reading. Your reading a difference in potential or voltage. This is assuming you have checked for DC voltage.

Dam I didn't even see that tiny button it would make to much sense to lable the dam thing.

apparently all the 12VDC power enters from that point an thats why all other fuses an breakers where uneffected.
I now have water pump, roof fan (after I adjusted the temp knob fan powered on).
thanks so much Tom
next I need to rinse out the couple gallons of antifreeze I sucked into the sys. then I'm road trip whorthy

good tips on testing a 12VDC breaker thanks George.

.
apparently all the 12VDC power enters from that point an thats why all other fuses an breakers where uneffected.so do all 3 types of power converge an enter into van at this breaker?
