Dimming Interior Lights

I have a 2001 Sunline T-280 SR trailer. On our last camping trip our interior lights dimmed low and after awhile went back to normal. They would be dimmed more than not all week long. Once the lights did dim a buzzing noise came from the electrical panel box which is located in the rear bedroom. The only time we did not hear the buzzing noise is when we turned in for the night and the lights were off. Is this a converter problem? this can not be safe hearing the buzzing noise.

Yeah it sure sounds like it. You might check the large lugs on the converter and make sure they are tight but it sort of points to a converter issue.

Is the converter located in the electrical panel area or at another area in the trailer?

Hi Bob

You may have a bad battery.
