Electrical Issues

2017 Aria 3901. Iím getting no power when batteries are charged. Nothing on either line. Once I start the generator everything works. Iím not sure if Iím even explaining it correctly.

I am assuming you are saying things like the 12 volt lighting aren't working until you start the generator?

First thing to check is if the USE/STORE switch is in the USE position. If in STORE, the batteries won't power your lighting, and when the generator is running it powers your converter. The converter then provides the 12 volts to lighting, etc.

50 amp DC breaker near batteries tripped or latching relay/wiring bad.

Not tripped
Iíll manually trip it again
It happened during use/store switch use
But use/store switch making switch noises
With genny on now (Iím boondocking), I get power but converter isnít charging batteries/no fan

100amp breaker seems fine
Trying to figure out if the internal mechanism of the use/store module is bad
So connect both positive cables together to over ride it?

If the converter wasn't on the house battery voltage would be under 12.7 VDC once the surface charge is dissipated.

I can’t tell what the battery voltage is when genny s off because everything is off

What abt BIM? Is that involved?
Blown Fuse under hood?

Get your hands on a good voltmeter, heck, even a cheap one is better than 'guessing'.

Success!!!

Found it
Itís the Use/Store module
It clicks on/off from the switch
But obviously is broken at the connection port

I circumvented/wired around it by connecting the two cables together

So Iíll be fine for the remainder of the trip
Then Iíll order a new one & re-wire

Iíll keep you posted....

It is fine, just remember to keep it plugged into shore power or the batteries will slowly die out. Just disconnect the negative from the battery if you do need to leave it w/o power.

You misunderstood me...
The Solenoid inside the Use/Store connection port is bad
So I connected both of the cables together on one side of the solenoid (which renders the solenoid useless)
And by doing so, it’s like not having a Use/Store switch.

All internal functions of my rig now work normally

So now I need to replace the solenoid mechanism & re-wire properly so that the Use/Store switch functions as it’s suppose to

My rig is always plugged-in or solar powered so I rarely have need for the Use/Store switch

It looks something like this...

Yes, that bypass will work fine until you get the latching solenoid replaced. And for future reference, the 100 amp DC breaker powers the generator start and hydraulic leveling pump. It is the 50 (or 70 in some coaches) amp DC breaker that goes to the latching relay.

Thanks for the response.

I finally found the 50amp breaker hidden high inside battery compartment, but itís a stand-alone without an external breaker (yellow flag). So not sure how one knows if itís bad.

By the way...with all the stress & commotion, I forgot to reset the 100amp yellow flag in the battery compartment.
For the life of me, I couldnít figure out why the Axxera radio wouldnít power-on
Well, well. Once I discovered & reset the 100amp breaker the Axxera powered on.

So I found a replacement relay/solenoid on Amazon for $34
Although one of the comments was that you can take apart and clean the connectors as they get corroded.
So Iíll probably buy one, and clean out the current one when I return home.

Now I wonder if the OP had found their problem.

Part arrived today via USPS regular mail
Took a little longer because it didnít come directly from the Amazon warehouse
But was a favorable price at just $34
Now Iíll install and the Use/Store switch will once again work properly.

I have never had the chance... yet, but once changed, open the 'defective' one to see if you can find the problem. May be able to make it into a good spare.

They say that once taken apart, itís just generally just corrosion that limits the solenoid connection.

Iíll report back with photos.
