Clicking in front storage bay

[Jlawles2]

A lot of people replace the metal junction box with one of these https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 this gives a better place for making all of those connections. When I did mine, everything ended up with a ring terminal on a post.

Thanks for the 7-pin out schematic.

And good suggestion on getting rid of the large
wire nut, I was planning on it too. Bad Design
by Grand Design. Go figure, not so Grand. It’s
probably a cost cutting measure to use them.

You may want to remove those large wire nuts and replace with a buss bar or similar, wire nuts do not hold well while a vehicle is in motion, I fear you may have this issue arise at some other time. Thanks for sharing.

Problem? What problem?? Good news and thank
you all who replied and helped. All comments were
very much appreciated and valued. I got it working,
it’s not clicking anymore and everything works.
I just wish I had a definitive answer as to why it
wasn’t working and why it is now? Here’s what I did…

Finally traced the wire related to the clicking
auto-reset circuit breaker to the electrical junction
box up inside (facing bottom) of the turning point
king-pin with 7-pin wires coming out of it and a bunch
of wires going into that box. (Thanks for
pointing me in that direction Country Camper & howson)
The hot wire Going into junction box which has
the 2-wire locking tab mechanism. That ohmed out
(had continuity) just fine on both ends. The 4-white
wires and the related mostly white wire with thin red
strip on it were all (5 total ) common wires stuffed into
very large blue wire nut. I Found my related wire and
found the other end going through a hole behind
battery In the wall structure by removing bottom cover
under storage area. There was another same kind of
very large wire nut with the 5-wires stuffed in it. I
Separated them all and found my wire and it ohmed
out good; so that perplexed me. I also swapped two
30-amp reset circuit breakers with the related
one that was clicking. I reconnected all of the wires
on both ends using same large blue wire nuts.
Put it all back together and it all works? No clicking.
No issues. All devices are working. Possibly
the related wire wasn’t making contact in on of those
large wire nuts? Idk? It seemed to be good contact
when I removed the large wire nuts and tape? Idk,
again wish I had a better definitive black & white
resolution to tell you, but I don’t. However, maybe
this forum conversation might help somebody else
troubleshoot a similar issue down the road.
Thanks again !!!

Here's the 7-pin scheme.

[Jojo2018]

Ok thank you for the good advice. I’ll give it a try
and posts results tomorrow.

Jojo2018 -- to check if that wire is for the 7-pin (Bargman) tow vehicle power input, do a continuity check from the 7-pin's power wire to the bus bar wire (with it removed from the circuit breaker as shown in first pic).

Again--make sure wire is removed from the power bar prior to doing a continuity test.

If there's continuity, the circuit is indeed the 7-pin wiring.

Now do a continuity test from the 7-pin power to the 7-pin's ground. There should NOT be continuity but due to the fault my guess is there will be a short.

I'd post a 7-pin diagram but I'm on my phone...sorry...difficult to work on this small screen.

On my trailer that wire goes to the schwintec slide controller. But I am sure GD wires everything differently I can tell you the red wire position one bottom goes to the disconnect (that the primary RV breaker between the battery and that wire) switch and the two black wire at the lower left, one comes from the disconnect switch and the other goes to the 12v distribution panel.

[Jojo2018]

Ya I believe you are correct. A quick check leads
us to that electrical pin box with wires galore in it.
The hot wire looks to be ok connected to a black wire
via 2-wire plastic connector with locking tabs.
The white wire appears to go in a very large wire
nut with at least 4, maybe 5 or 6 wires crunched into it.
It’s very tight up there to get into. Possibly one
of those white wires just isn’t making
contact in that mess of a very large taped wire nut.
I’ve seen home wire nuts with multiple wires in it
vibrate loose before. I’m tied up tomorrow
Tuesday all day and will
troubleshoot more on Wednesday and try to
verify all of those wires.
Thank you all for your replies.
Stay tuned for Wednesday.

Ya thanks, never thought about the tow electric
wiring. I’ll have to check that.

I am wondering if that wire is the + 12 v from the tow vehicle plug, this would be found in the silver metal box located inside the pin box. I am not sure what that wire does, just trying to help. It may also go to the leveling control which is located on the ceiling of the front storage. I do not think that it goes up into the inside of the trailer. There is a wire that goes to the power distribution panel which will be a larger 6 ga wire which will feed most if not all of the inside circuits.

Thank you, that’s the strange thing. All lights inside & out,
all fans, one slide, awning, refrigerator electronics,
Leveling system, tv antenna booster all work that are
12v battery related when not plugged into house electric
with that one wire removed. I have not yet tested
furnace, nor water heater or pump in this mode,
but will tomorrow night. Maybe a ground wire is off or
broke somewhere. The red&white wire that goes up to
bedroom must go the ceiling area? I removed the
driver’s side plug in receptacle, reading light and fan
and there’s no red&white wire behind the wall panels.

I've never done trouble shooting on a circuit with an auto-resetting circuit breaker. When it's "clicking" every 25-30 seconds does this mean the the breaker is tripped and the device side of the breaker is dead (no voltage flowing), and then tries to reset unsuccessfully? Or does it mean the circuit is overloaded and it takes 25-30 seconds for the breaker to trip, and it keeps repeating the cycle?

[Jlawles2]

Start looking inside the unit for a non working appliance or other device. Try slides also. This may help point to the path the wire may be taking.

[Jojo2018]

We have traced the wire and it goes through the driver’s side propane panel enclosure somewhere up into the bedroom driver’s side, but can’t see where it goes from there without ripping out walls?
