Hmmm, I checked most of the AC side of the wiring when I picked up. Now going back to it within week, to pull covers and make sure all are tight. Since all of it is copper wire, it should have been torqued to the required value when install is done. Not looking forward to this job, because got to do it with everything off. Master switch's in rear passenger side bay, genset off, AGS off, inverter off. Flashlight time, or battery powered work lite. Glad mine is in the front cabinet instead of the bath area. Will advise. Suggest to all, you take the time to check all connections as tight, don't overtighten them either, makes it just as bad. In Last MH, it was an electrical nightmare, and as Neal Said, the Connection in the TS need to be checked as well. Why should we have to reinvent the light bulb here, Newmar says they have excellent QC. But we had 31 fixes done at end of first year, many things, should have been caught at the QCI inspection. Newmar, should have a volunteer customer, and the QCI inspector walk through coaches, and I will wager, I can find several things, they miss. WHY? Simple, I could take my time, and it's not under the skin issues, I am talking things the little lady's will complain about. Oh, I could go on and on.
