If your too far away or don’t feel like spending the money on fuel for a $5.00 part, you can replace it yourself. Just make sure to match the rating (should be stamped on the breaker) and put the leads on the right posts, they are color coded so just match new with old.

Unless you have a battery disconnect, then you will have parasitic draws on the battery. Two choices: take the positive cable off the battery post, or install a disconnect on the positive lead. Installation will depend on type/brand but I’m sure there are numerous videos.
