So today my car battery died, couldn't even be revived with a jump. I was able to walk to an auto store to get tools and a new battery (damn that mfer was heavier than I expected). I had never had to replace my own car battery before.
I screwed the fastener nuts the wrong way for like 5 minutes, cut my hand, and ultimately accidentally crossed the positive and negative terminals with a wrench that exploded in sparks. I don't even know what stopped me from being electrocuted but I didn't feel a thing.
While I'm happy I was able to take care of it myself and will be able to in the future, I also feel like such a dunce for not knowing wtf I was doing and almost shocking myself
I've never replaced a car battery and wouldn't know how to begin, so you're ahead of me.
I always forget which terminal to start with but luckily they’re at the same height so I can set my wrench down on them while I look it up on yt
Always disconnect negative first, so that if you accidentally touch any metal parts near the battery while disconnecting the positive terminal, there's no path for it to complete a circuit. I also have a socket wrench with a rubber-coated handle that I like for working around batteries; I think it was some like $8 Popular Mechanics-branded thing from Walmart that I got like 20 years ago.
There’s a reason insulated hand tools exist! If electricians will spend extra money on it, you know it’s worthwhile lol
