2016 FB22 USB Problem

[jrkemist]

My 2016 22' Bambi has a fuse problem. All of the USB ports located next to the radio and bed have stopped working. The documentation is confusing but all of the other 12 volt things (lights, radio, etc.) are working. Ideas?

Just some thoughts/ideas:

Can you check your USB cord in the car to make sure it is not the cord or plug?
Does your device work OK in your car?

Will be interested to find out the answer to this. We use that a lot to listen to music.

Our Bambi is not hooked up to our car. We use it as a permanent home and it is permanently hooked to shore power. The USB ports worked when we put it in place last November. One bank (next to radio) went out in December, and the second bank (next to bed) just went out and I don't see a fuse or breaker for each 12 volt bank.

I'm going to clarify what was already suggested: Plug your USB device into something besides your trailer, to make sure it works, before going further. If it works elsewhere, then you can get back into the trailer plugs.

I can't get the image to paste in, but the 2015 Sport parts book that I downloaded from the AS corporate website has these fuses and parts listed for the interior 12V.

Page II-25

12 V interior Receptacle
195466-250 12 Receptacle w/cover
195466-251 30 amp fus holder w/cover

Fuses:
part 500773-03 Fuse, ATC, 12v DC, 3 amp
part 512318 Fuse holder w/1 amp ACG Fuse
part 500883-01 Fuse 12 CSA 1 AMP
part 681936 ACG-1 Fuse
part 510696 Holder, Fuse, In-Line

Suggest you go to the AS website and download this for your 2016 and save the file. I figured that this would be a good document to have in 10 years to find replacement part numbers.

While traveling this summer with our 2016 25FC, we thought one bank of our USB cables were not working. It turns out even though it felt like we had inserted the USB in properly, it took an abnormal amount of pressure pushing the plug in and it worked. I think they are using cheap female USB plugs. Try pushing very hard when inserting and see if it starts functioning.

USB outlets provide 5 VDC to your electronic devices. They can usually either provide 1.5A or 2A of power. IPADs charge best on 2A. USB outlets usually use 12 VDC as a power source although 120 VAC units are manufactured. I am guessing by their appearance that these in the Airstream are powered by a 12 VDC circuit.

You may want to get a flashlight and look at each of the USB outlets to see if the plastic guide inside of the outlet opening is not damaged. Sometimes a person may try to force a cable into the outlet upside down and it can crack this guide. The outlet then has to be replaced.

I've never seen a schematic showing the 12 VDC connections for the USB outlets, radio, TV antenna amplifier, furnace fan, furnace controls, refrigerator control circuit, ceiling fans, LED lights, water pump. Has anyone come across such a diagram or a listing of what circuit each item is on?

USB plugs do wear out too. Test in another usb outlet, of use a USB/110v adapter like you get with most devices or a computer.

Once you know it will charge from another source check the fuses as mentioned above.

Finally, if that yields nothing, pull the USB outlet out and test for voltage at the back of the outlet. If you don't know what that means then you probably should ask a friend that is hand with a voltmeter.

Keep us posted.

Yes, please keep us posted! We have the same problem in a 2015 International. The back USB charger has gone out, been replaced by the dealer, lasted about two days and died again �� We're getting suspicious of trying to charge two devices simultaneously (it has two USB outlets in it). The two in the front (also with two outlets each) seem to be just fine though we just use one USB outlet at a time there to charge two devices simultaneously.

Our 2015 airstream 22fb also having issues with bedside USB ports. Ones up in cupboard by stereo are good still. Anyone figure it out in the end? Thanks

We have had problems with these bedside USB outlets as well in the past. I simply replaced them with a new panel like this:

You can put whatever mix you want in the holes. We used two usb outlets, a DC "cigarette lighter" outlet for charging my laptop from a 12v power adapter, and a switch to turn off the power to the panel.
As I recall, I had to do some router work to enlarge the wood panel opening for the bigger power unit.
