Power converter failure

Unread postby Dgrifin » Sun Sep 07, 2014 11:49 am

Was working fine, then I go to plug it in to shore power, and nothing. No click, Nothing. Breakers seem to have
plenty of snap left...fuses are ok... does anyone have any idea how to troubleshoot this thing? There is precious little in the service manual on it...like precisely nothing. It seems to be passing 12 volt ok, but nothing for 120AC. Any ideas? Should it need replacing, does anyone have any for sale?

Thanks in advance guys

I am thinking that maybe a relay which feeds power to the converter went
out? that would explain why there is no "Click" when I plug it into
shore power. Does anyone know where such a relay would be located... it
must be a pretty big come to have clicked so loud... any help is appreciated

Does Shore power pass through a relay before the breakers? That would explain the click..and why its not clicking now

Nope power goes from outside cable to main breaker then main breaker power goes to others..

If you don't have power in main breaker something is going on the cord. .

The main 30 Amp shore power cable connection at the converter should show 120V on a voltmeter at the input side of the main breaker. If there is 120V then check for same at the output side of the main breaker. If there is good input but no output the breaker is bad internally. If there is no 120V at the inlet side trace the main 30 amp cable back from the inlet side of the main breaker to the plug end A short distance under the driver's side dinette seat back to the rear compartment.) Must be either a break or the plug end is bad or there is no shore power being supplied. The 120V portion of the convertor is very simple and just passes inlet power to several breakered sub-circuits. The 12V portion is the actual 'converter' portion and runs through 120V to 12V converter then to 12v fuses.

GFI panel circuit breaker is finished or needs to be reset, or, gfi receptacle needs to be reset or replaced(cdn models)

It can be critter issues as well, but get your volt meter out and see where the voltage stops. Be careful !


Cheers, Scott

The shore power works basically the same as the house incoming power.
In our case you are plugging into your house (garage) and you should be able to prove that the receptacle works by plugging something else into it or using a meter.
The shore wire goes directly to your power panel to the first breaker, the main which is a 30amp, and from there it feeds the other breakers. One of those breakers feeds the converter.
If your house receptacle has power then check one of the receptacles in the LS for power. If it has it you can be somewhat confident that your problem may lie with the converter.
Look in the Files section as there is good information there on the converter.
Hope it helps,
Rick
