Check your fuses for the right labels
I just spent the last couple hours wiring in a 30A inline fuse for the landing motor on our 5er, it was hot wired directly to the battery / power not fused to the power converter. If the motor or on/off switch had shorted out we would have had major issues. While I was at it, I figured I'd check the 11 fuses on the power converter since the "hitch" fuse didn't appear to affect any of the lights in the hitch area. Turns out, the Fan and Hitch wires were interchanged on the power converter per the labels. I'm sure the quality control of these units is going downhill, shouldn't proper fusing be checked at the factory ? It wasn't a major job to change the wires, but it makes me wonder about other things not being checked that I can't see or access.
