15 amp fuse in 2018 320 cs-s below bench in control center for overhead lights keeps popping

Lawyerboy

Happy Thanksgiving to you and yours everyone.  So, noticed no overhead lights or porch light.  Went into the converter center and noticed a red light on to the right of the 15 amp flat blade fuse.  Bought replacements, and each time I install and send power to the trailer, that one pops again.  I have the above fan running.  The radio is lit up.  I have a dehumidifier plugged into the gfi outlet left of the converter. Any thoughts would be appreciated.  TY so much.  Mark

While I don't have direct knowledge of the 2018 CS-S wiring . . . in general nüCamp connects all the 12VDC lights to the same fuse or two fuses.

For the12VDC lights that are not turning on . . . the most likely issue is a bad connection at one of the light fixtures.  One of them is shorting the +12VDC to the return/ground wire; it could be in the fixture (bulb area), switch, or the wire connections.

Again that's the most likely source, investigate and let use know what you find.

Thank you.  Ironically I replaced the galley overhead light. The wire was short.  Wonder if it came loose. Will advise.

So reconnected that galley overhead light.   Power off and installed new 15 amp blade fuse and seems to be the culprit.  For now at least.  Ty
