Electrical problems

I’m not sure what’s going on on my 23 foot flying cloud.
Here’s the issue the fans are not working as well as the furnace and overhead lights.
I’ve checked the breaker it seems to be working the small fuse on the number 2 circuit and light does not come on when you pull the fuse out.
Any clues?

Do you have a multi-meter?
Pull the fuse. Using the ohms scale check the fuse. It can look good, but be bad.
While the fuse is out. Use the DC voltage scale and measure the voltage at both sides of the fuse socket.
Anything?

Hi

Do any other 12V devices work? If so which ones?

Are you on shore power? If so, do 120V devices work in the trailer?

If all 12V is out, when was the last time it worked?

What position is the use/store switch in?

Lots of fiddly details and directions this could go ......

I had a similar problem in my '19 22FB Sport. Front interior lights and Fantastic fan, on #1 DC fuse, would not run. (Fuse would blow immediately as confirmed by the indicator light). I got a wiring diagram from J-C and took it to a local shop, who found that a Fantastic mounting screw had skewered a wire to the fan.
I'm usually "capable" on these things, but this problem was tricky. Talk to J-C and get the help you need.
