    The way you get good at it is by screwing up several times along the way. So, you’re on the way to being good!

      Sucking at something is the first step at being kind of good at something

      In general yes. Replacing a car battery is something you don't wanna screw up even once.

        One time while screwing a battery into a jeep, I started hearing a strange noise/feeling an itch in my hand. It took my like an entire minute to realize that I was touching both battery terminals and what I was feeling was electrocution.

          Fortunately, 12 VDC isn’t enough to do any lasting damage and certainly can’t kill you.

          (Yes, I know “it’s the current that kills you,” but do the P=IR on average human body resistance and deadly current and you’ll find ~30 VDC is the minimum voltage across the heart that can kill an adult)

            When I first started working with electrics, they taught me to keep one hand in my pocket when I'm screwing something into a battery or other electric terminal. It's a good reflex to develop because it prevents you from mindlessly touching something with your off hand that completes a circuit.

              We called it the “One Hand Rule, no not that one”

              That and removing all watches, rings, and necklaces are the most important precautions when working with live electricity. But, it’s always best to not work on live electricity wherever possible

          I was once shocked when I touched a spark plug wire on a snowmobile, even though it was isolated and I was wearing thick gloves.

            I actually managed to do this once. Turns out the car had a fuse SPECIFICALLY to prevent this kind of fuckup. So hats off to the Mazda engineer in the 1990s for including that. Actually, I assume these are fairly common, but it had never occurred to me that such a fuse even existed.

              Unfortunately my friends kia did not have that.

              They just tapped it and it wasn't bad enough to completely kill the car, but everything besides the basic functions were toast and it had a bad battery drain. Radio was toast, power windows and locks toast. A/C was intermittent, but it ran and drove. He installed this water tap looking thing and every time he got out of the car he had to turn it off.

              Then again this is also Kia who didn't include an immobilizer as standard until 2021

        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

            A car battery doesn't have enough voltage to even tickle you* so you wouldn't even know if you zapped yourself. (*assuming you are touching it with y'know your skin and not your tongue or something even sillier)

            Buuuuut if you touched any bare metal bits of the car while touching the positive terminal, for example when fastening the bolt on the positive terminal with an uninsulated tool, then you did just zap yourself for however little that matters with a 12v battery. ;)

                The flavor of current also plays a big role too. Car batteries are Direct Current, whereas your 200v outlet was likely Alternating Current. Essentially, even 200v of DC wouldn’t have been as “painful” as the AC you experienced although I’m not playing with either. Part of the danger is the way the alternating current has a tendency to contract your muscles, keeping you in contact with whatever the source is. DC tends just spark, bang, shove you away.

            You'd basically have to roll around in salt water for 20 minutes to zap yourself on a car battery -- they only put out 12-13 volts DC, but there's a decent amount of amperage behind that (typically 550+ for cranking a gas engine, though I've had batteries that were capable of around 1,000). With car batteries, your two main safety concerns are going to be tools or metal parts (e.g., battery retaining brackets) getting extremely hot if they bridge between positive and ground -- and the risk of burn injuries that would come along with that -- and the battery just outright exploding and flinging hot sulfuric acid everywhere. The second one is rare, since the battery will usually discharge itself before that point.

            Hybrid battery packs -- the ones typically stashed under the back seat, not the 12V starter/auxiliary battery that you may find under the hood or in the trunk -- are a very different beast, and typically put out closer to 48VDC. Those beefy bastards absolutely can kill you.

    Comrade, I'm going to assume you're young. I'm not. But I can tell you as the handiest person I know, I got here because I never stop fucking around with things over the years. Some of my tools have chunks melted out of them from accidentally shorting a car battery. I've skinned my knuckles, stabbed, electrocuted, burnt, cut, glued, bumped, and bruised myself, and I expect I'll do it again some day but hopefully less often. The difference between us is time spent being stubborn about wanting to know how things work and a lot of times needing to save money. Don't get down on yourself, you changed your battery and that's more than many people will do.

    Keep fiddling with things, you'll get there. But also, take your time to think through hazards, it makes it a lot easier. Don't ever rush handy/repair/maintenance work.

    what stopped me from being electrocuted but I didn't feel a thing

    Sounds like the electricity was going through the wrench and not your hand. The real dangerous electrocutions are where you touch negative with one hand, positive with another, and the electricity goes across your heart on its way to complete the circuit.

    But anyway as a certified handy guy who has done installs and modifications of all kinds professionally all of this has happened to me before too. The only way to get good at it is to do it every day, and most people just aren't doing that.

    I've made many mistakes when fixing my own cars so take it from me it happens. There's this time I put a battery that was too tall in my sister's car because we didn't have the money for the proper battery, shit make sparks with the hood as it welded it. I fixed that with some electrical tape insulating it. There's this most recent mistake where I bored a hole into my new radiator, fixed it with some jb weld few days ago.

    Among my friends and family they see me as some sort of mechanic but the sheer volume of fucks ups is pretty massive. Everything runs at least and not being a trained professional I'm doing alright all things considered so be easy on yourself. You didn't get majorly hurt or anything and you learned some important lessons as long as you don't do them twice you're good doggirl-thumbsup

        So real, I've mostly been put in this because we don't have the money for an actual mechanic. I will say the real curse of being handy is the permanent "temporary" fix. My ac compressor crapped out and made my serpentine belt fall off, I ran a bypass thinking just for now till I fix the ac fixed. That's been almost 2 years now buggy-disappointed

      Absolutely this on confidence. The first and most essential step is letting yourself be someone who can solve the problem. Next is being careful about it, sure.

      Another big part is just careful attention to the parts available, as a huge number of intimidating problems (especially in plumbing) are solved by carefully browsing the catalogue and following up on the leads it offers.

    Some months back I replaced the alternator in my vehicle. I've been working on cars on and off since I was a teenager in the last century, but I mostly get by from watching videos and reading the manuals. So I watch a bunch of videos, get the alternator out of my vehicle, and then proceed to get the new replacement stuck for like 3 hours when trying to put it in. See, all the videos I watched had a hard time of getting their alternator out, so they had to removing a bracing bar. But not me, I twisted it right through the gap, LIKE A PRO! doggirl-thumbsup So when I'm watching these videos and they're all having no problem getting it back in, I'm pulling my hair out wondering what the heck is happening when it suddenly occurs to me how I screwed myself and that damn the bar needs to come out. lol, what should have been a few hour job took me two days. LIKE A PRO! catgirl-cry data-laughing

        I do think there is genuine value in understanding how the things you own function and being able to do some degree of first aide on them but even that can only extend to so many different things. Can't know everything. You can learn anything though. If you wanna learn car repair, do it, if you don't. No real need aside from what you'll need to know just to keep a car (gas goes in gas tank etc)

    I dunno how people learned 30+ years ago... families passing along info, friends maybe. nobody in my family knows shit, except calling whoever has money and getting them to throw money at poor people until the problem is no longer present.

    I left home like about 20 years ago and became curious how to keep my shit from falling apart when some critical machine, appliance or mechanism stopped working and I only had $30 to my name. learned stuff from coworkers, helped them work on their own orojects as an extra pair of hands in exchange for their knowledge. once YouTube became a thing, that's been real good.

    I took some adult Ed. "shop" type of class at a local agriculture school. that was riveting. I still watch YouTube videos for stuff though.

    its a real pain to sort through all the AI slop though nowadays.

    I think as we settle into imperial decline and become intermittently disconnected from various supply chains.... having curiosity and an attitude for tinkering is going to be crucial as communities contract into some kind of neo-mannorialist/resiliency-based whatever the fuck.

    my family still doesn't know shit about fuck and they all seem to refuse to learn anything, treating me like I'm some kind of eccentric throwback for trying to muddle my way through problems and understand mechanisms.

    I am perennially disappointed and frustrated by their incurious approach to the world.

    I find people who want to at least try to understand a problem and explore their DIY options to be kindred spirits and fast friends.

        I wouldn't feel bad, we all start somewhere and it's a continual, slow process of learning how new things work, repurposing old things to serve new needs, and one is never done learning.

        if I had any advice it's to cultivate patience with yourself as you learn, because if you do you can become exceptionally talented/knowledgeable as you incrementally grow your capacity.

        learning in these situations can be extremely frustrating, especially if it doesn't solve the way you needed it to. but you learn what doesn't work, what's a "dead end" and that's just as important too.
