I was talking to @ericnliz
yesterday and fuses came up. Most of us have had that necessary but annoying 30 amp fuse blow at least once. You are usually not aware immediately until you notice that your battery is not charging. Or none of your 12 volt circuits are working. Hopefully you have a replacement at hand. Unless you already used it and haven't remembered to buy a replacement. Oh yeah and in my case it's usually dark. Well a simple solution is an auto resetting circuit breaker. Available at any auto parts store they come in most amp ratings, and are a simple plug and play.
