Default Clicking box in ceiling.

Hi,

There is a 3X3 inch (approx) electrical box mounted on the ceiling of the right bay above the passenger seat/windshield near the outlet for the TV in my SP 36 1990.

That box is open and in it I can see a metal plate jumping up and down, clicking loudly, as the lights/all electricity flicker off and on in time with the metal plate.

This is observed when the generator is running. I haven't hooked up shore power yet.

Replace the box or is there something else making this happen that I should look into first?

As always, THANK YOU.

A picture would be helpful as we could tell if it was:

A: A DC controlled relay for switching on/off the 120V AC lights.
B: A 120V controlled relay, possibly for inverter switchover.

If it's the former, then there is likely a 12V DC issue. Are the batteries all charged up?

If the latter, then the AC may be dropping in and out. Trying shore power would help diagnose. Do other 120V lights seem to work fine while this relay is chattering?

And it is possible that the relay in the box is bad as well.

Mose,
An electrician is coming this week to wire a plug for shore power, will check that part out for sure as soon as I can.

I'll take a photo when I get home from school. ALL the lights and ALL the things (microwave panel, etc.) flicker in unison with the clicking.

Batteries must be in need of a full charge. It's been a long winter.

Thank you.

If everything is flickering, then there's likely nothing wrong with that one relay, so no pic needed. Possible the generator is not maintaining voltage. However 12V DC is also used to switch many relays, so make sure 12V from batteries is solid before going too far.
