So - camping trip #1 went pretty well in the new trailer. Had some decent weather, didn't hear any generators and overall had a relaxing weekend. Man it sure is different coming home from a trailer weekend than a tent weekend. Pulled up, emptied clothes that were almost normal clothes (not summer/spring/winter/rain clothes for every occasion and weather type). Moved some stuff from fridge to fridge. All done. No coolers, dishes, cleaning, washing, throwing away unused food that soaked for a few days in melted ice cubes (water).
Anyway, got to site and had no power. Fortunately it was a 15 amp site so was able to plugin and be okay. Anyway, I found what looks like a blown fuse on this thing attached to my battery
I'm not 100% sure it was blown as the fuse looked in bad shape visually anyway, white oxidization, it looked like it expanded, but hard to tell if the actual metal thing was broken. I'll go buy a new 30 amp fuse tonight and test.
That said, the fuse holder (little black box on the green wire) looked in rough shape too. Is replacing that thing (green wire or fuse holder) a lot of work or difficult for someone with no electrical knowledge and only a pair of wire strippers for doing speaker wire and crimping butt connectors?
Also, now I have no idea if my batteries are actually charged. What do I buy to test them or store/charge them (if it's the same device might as well buy only one thing).
