Electrical surges in brand new Rockwood Mini Lite 2507S

[JKMiner]

Getting ready for my maiden voyage in my new 2019 Rockwood Mini Lite 2507S.

I was plugged into shore power for a day and inside packing stuff when I noticed the inverter cycling over and over again like it was charging the battery.
About 4 seconds charging, 4 seconds off.... over and over.

I made sure everything is turned off and it keeps doing it.

I unplugged from shore power and have just the dome lights on inside.

I notice that the dome lights dim for 4 seconds then full bright for 4 seconds ... over and over. So, something is turning on and off.

I turned off the refrigerator and it still does it. The water heater has the electrical switch off.

The WiFi Ranger that came with this from the factory runs on DC I turned it off too.

Called a hotline and what do you know, they helped me figure it out.

On the main panel for the switch that controls the dome lights, the wire was loose. I tightened it and it stopped going bright and dim. Just bright.

The question is, why did it go on and off like that if it was loose? I can see intermittent but what the heck?

Anyone?

You're talking about a CONverter, not an INverter.
Mini Lites do not come with factory inverters.

When you say “inverter cycling” I assume you mean the converter fan is running. If not please disregard this post.

That said, the converter fan running is normal. What is unusual is on/off without you putting any additional 12v load on it.

I suspect the loose connection you had was causing an arc which would look like an additional load to the converter and make the fan run without you switching any additional load on the system.

It’s great you were able to find the loose connection with hotline support.

Yes, I had the term wrong - I did mean the converter.

And you are right that it was likely the arcing of the loose connection that was causing the converter to kick on.

I guess the thing that continues to confuse is the consistent cycling on and off. Didn't seem random at all... No biggie. Thanks for the thoughts.
