RV plugged in noise at electrical panel

Question

Now I been away from RVing for about 10 years. dove back into it with an older very affordable 93 Dutchmen. When I got it home and plugged it in I hear a humming and clicking noise at the panel that is located under bed. any ideas what this is from? Battery charger? Is this normal? I don't remember that on my old unit...could be annoying when trying to sleep. any feedback will be helpful....Jer

It wouldn't be unusual for the converter (battery charger) to hum a little but there shouldn't be any continuous clicking.

Hi,The older units were quite noisy. I'd upgrade, myself.

The panel in my 94 Classic always hummed but didn't have any clicking. It was located in the bathroom.

I would be taking the cover off to see what is causing noise. May be bad connections in AC/DC box.
