Is that a slow burn fuse? I wired cars for a living a long time ago, this looks super dangerous.
If I plug the thermostat wire back in without the fuse will it ruin anything?
That’s a bunch more than a bucket full of ohms
It’s your over temp fuse. I had one fail right after I bought my trailer. I jumped the connection to test the water heater and it was fine. I bought a few very cheap on Amazon and replaced when it came in and kept a couple spare fuses. I haven’t had an issue since. I really thought it was a fuse failure due to the climate was mild and it failed immediately after a camp setup. Good to keep some extra wire connectors as well or a simple part like this will prevent the water heater from working until repaired. Cheap fix tho unless there is a real issue. Ohm test showed the fuse was not working.
