Devon sunrise split charger not working

Removing the fuse should do the job with the fridge

Try the same with the water pump/interior lighting fuse, that's the only other possible load according to the wiring diagram.

Otherwise, other than corroded connections somewhere, including from the trailer relay, I'm struggling to think of something to suggest.

Hopefully someone else has seen this before.

I’ll look at the crimps and see how they look. Fingers crossed that will reveal something

Thanks for the help
