Electrical Odity

We bought our 2017 25 FB last October and have used it a few time, but wife and I havre been living in it for the last several weeks hiding from society .

Spending this much time in it, we have started to discover a couple oddities. One was the water pump (another thread). The other is electrical.

When we turn on certain lights we get a flicker in the light above the dinette. Iíve also noticed that if the light in the shower is off and I turn the vent fan on or off the shower light will flicker on for just a fraction of a second.

Any thoughts on what might be causing this?

Ck the sockets for both, loose bulb...bad connection, usually a faulty ground.

Yup +1

Flickering usually has to do with connection.

Check the wire connections at the terminal blocks for a loose ground or revered polarity. A multi-meter is a good tool to have for electrical diagnostics.

As the others indicated, it is likely a slightly weak common ground/negative wire. LED lights using a common ground/negative can flicker and light up due to current fluxes and voltage variations on the common side since it is always connected to the LEDs as opposed to the positive which is switched.
