I've taken both 2100V and 250,000V at 1000W delivered. I know because I was measuring it  .Surprisingly 2100V hurt more.

I've been shocked plenty of times, but the only one where I actually got hurt was loving around with a disposable camera flash. I don't know why but that one stuck with me.

I had an uncle who had an hvac company growing up. My cousins and I used to shock each other with manual fireplace starters for fun.

My friends and I used to charge up one of these in my high school tech class and leave it laying around in conspicuous places for unwitting curious rubes to pick up It was never not hilarious to hear a startled yelp and see the thing go flying across the room. We even got the teacher, who I think was more amused than anything (after the initial shock wore off, of course). The one we had contained a sizable 330v capacitor, IIRC. I don't remember the uF.

A charged capacitor is also called an idiot grenade for that reason.

The only shock I've experienced that ever caused any lingering issues or real pain was a static charge that built up while I was driving a forklift around and when I touched a machine (while still seated on said forklift) there was a small arc flash and it felt like something punched straight down my arm through my index finger. I was barely able to move my index and middle finger on my right hand for over an hour and it wasn't until the end of shift before I could actually fully close my hand again. My boss was pissed when it was discovered the forklift had no proper anti-static strap. E: My brother and I used to challenge each other to hold onto electric fence wires when we were kids, could barely keep my hand on it for more than a half dozen shocks or so. After I got goats at the farm I could hold the electric fence wire (I think it was around 10kV, maybe?) for 10 minutes solid while letting the goats in an out of the barnyard cause I was too lazy to shut the fence off.

I was once testing for spark but I didn't have a remote starter hooked up. The plugs were too far to see from where I needed to stand to hold the key so I picked one up, held it against the block and turned the key. I don't know what I expected but it was certainly making sufficient voltage.

I've been shocked by distributor leads, it's definitely unpleasant, our autoshop teacher let us play with live leads off of a working distributor model. We shocked and burned each other for like 10 minutes before he put away the model, it was one of my favorite memories of that class

I was repairing a lab strobe light. Strobe had two sets of leads, a kilovolt supply to ionize the tube and a DC supply to charge a cap that discharges to produce an arc. I take it all apart, resolder the leads, and figure hey, I'll turn it back on to check if it works properly before I put it all back together. Which which lead the hand holding the lamp was touching. That was the low-current side of the transformer, so I just made a noise like "hnnngh" as every muscle in my upper body hypercontracted, and I dropped the lamp on the bench. Everyone in the shop turned around and looked at me and collectively realized in an instant what had happened.

The most painful thing I have ever experienced in any way was from just 48V DC (or thereabouts). I was installing a phone jack, and needed to strip the wires. Being too lazy to fetch a tool for it and being somewhat young and stupid, I just did it with my teeth. Works fine for that kind of phone cable and something I had done before. Only this time it was actually connected to the phone circuit. Teeth are full of nerves that have a high-bandwidth connection straight to the brain, and are apparently decent electrical conductors. I just remember pain on a level I had never before thought possible, my head sort of disconnecting from my body and just focusing on experiencing said pain, and then nothing until I was laying on the floor, things sort of spinning. According to relatives, I had been laying there screaming for a while. Have never stripped wires with my teeth since. They taste of pain.

This is what happens when you fit hollow camshafts with pressed on lobes as I assume a cost/weight saving measure. This one included, they always run fine but normally have low common rail pressure codes or similar. I think I've changed at least 3 or 4 per month in the last year or so. This one was out of an Volvo FH16 750hp  One more:  The gearbox filter on these trucks is a cartridge filter with a plastic cap screwed into aluminium. If you dont clean up the outer edge of the housing when you change the filter you'll tear the cap seal and all of the oil will get pumped out. Out of all the sensors on these automated manual boxes none of them are for oil level. warcake fucked around with this message at 19:22 on Mar 30, 2018 |

That'll wake you up faster than gas station coffee.

When I was getting my private pilot license many years ago, the flying school I was at had a really nice O-320 cutaway on display, with sawed off propeller so you could turn the engine slowly...and a live magento and wires on it. So naturally, being a bunch of stupid teenagers, the game was for four of us to each grab an ignition wire, and have someone else crank the propeller until someone dropped their wire.

I could see the one rocker contacting the spring keeper, but didn’t have enough knowledge to figure it out. Can-actuated injectors in diesels aren’t a thing I’ve encountered. cakesmith handyman posted:The cost savings are fantastic, as long as they outlast the warranty... That works until people stop buying your poo poo because it keeps breaking just out of warranty.
