Not surprised. I would imagine you'll find a wire nut undersized for that amount of wires. I had a similar setup in my Momentum, 14 wires all wrapped together with a wire nut and tape....yikes. I undid it all and used a ground bus bar to properly connect all the wires.

Yup - our DC wiring is the same with all the grounds under a single marrette, wrapped in electrical tape. I had the pleasure of having to open that up when I kept getting 'trailer disconnected' messages in my TV.
Am I crazy here (and it's very possible 🤪 but shouldn't there be a cover over your wiring, or did you remove it before taking the picture?

You will find a large blue wire nut holding all the wires with the pig tail going to ground (lower left) in photo. The solution is to ground each wire, or pair of wires to the frame using additional grounding screws and crimp ring terminals. Or install a grounding bar and tie them to it.

I found this same mess on my 5th wheel during my solar install. Documented over at the other place.Last edited by powerscol; 06-06-2021 at 10:38 AM.

I did not remove anything, that is as shipped from the factory. I will be improving it with proper terminals to a bar in the very near future.

I used a self tapped screw holding a strap that the solar hookup wire runs through. I cleaned off the paint to give a good contact surface. It's about 5/32" diameter with a broad flange on the head. I used a pre-made 6 ga. jumper to connect an 8 place 3/16" post terminal strip and ran all the grounds to one side of it with ring lugs crimped on the wires. Limiting each post to two wires and using a common buss strip on the other side. I have two spare slots now. While I didn't notice any immediate difference I'm sure it is better and more secure than what was there. Working industrial electricity taught me the importance of good ground practices. What a smart engineer once showed me that is often overlooked was, due to current flow the ground wire needs carry the same current as the power wire so it needs to be sized accordingly.
I did the same when I wired the fans and temperature switch for my refrigerator.Last edited by Wicked ace; 06-06-2021 at 06:08 PM.

Anytime you can replace a wire nut with a crimp connector, you have made a step forward. They are good a stick house where there is no movement or vibration, but beyond that, it's a problem waiting to happen.

Did you run 2 wires to some of the grounding screws on your negative busbar? 14 - wires is a big number
Re-pack bearings necessary?
