2020 Reflection 31MB lost 12V power in front half of trailer

[EdwardK]

Good morning.
I fixed the problem!! Thank you everyone who helped me out.
It was the loose connection (I think it’s ground wire?) in the bathroom fan. The dealership changed my roof because of bubbles and when they put the vent back on, they didn’t wire it properly. I took my trailer out for the first time two weeks ago and all that vibration from driving caused to loosen the wire.
I really appreciate all the members’ input and I am glad I don’t have to drive 2.5 hours to my dealership.
Also Thank you Howard for the detailed explanation of the wiring. I would never figure out which wire is which.
Now I will have to start my DIY Lithium battery pack that I got from Alibaba. I will be back for more questions.
Thank you again.
Stay safe.
Edward.
