I've had some fridge problems and while checking the power center, I found that the fridge fuse, which should be 15amp was instead a 30amp.
I don't see this affecting the thermal fuse tripping I'm having problems with but it sure initiated a quick around the trailer fuse check!
Found a setup I like in battery case. The fuse on neg post is a 200amp with ring connectors. A ring is attached directly to the battery post. Can't get closer then that.
