Message 13869 - Posted: 4 Mar 2009, 17:47:50 UTC - in response to Message 13853.  

might as well work on your car battery while standing barefoot on your concrete garage floor.

How about getting zapped (a few times) from a distributer wire while working on the engine timing. My ignition coil puts out 45k volts. :P

While standing in a puddle of gasoline.

Except that there's no HV around unless the PSU has failed and grounded to its case, or you open the PSU, or you have a HV water pump that somehow has exposed leads, etc.

Which is essentially what I was suggesting, less the antistatic mat, which is of course a good idea as well.

So you've tried it then? :P

When I didn't intend to ;^)

The real danger in that scenario isn't the shock (which is unpleasant enough) but that, in yanking your hand away reflexively, you'll yank it right into the cooling fan or some such.

I'm glad we would both suggest the same thing. But then it must be a few years since I used an anti-static mat, or wrist strap, or grounded a PC - but I've never lost a component yet, and like to think I know what I'm doing (touch wood).

Mind you, there was that SIMM that died with that scorch mark in the RAM socket which killed the motherboard... The red wine that killed the laptop doesn't count - drinking and surfing in bed isn't usually required with anti-static mats :P

Leaning from the passenger side there isn't much chance of doing that. Right hand on the timing gun and left hand on the distributer. Just some nice Jolts. I've changed the wires out since, so no more zapping. :( :D

The real danger

I had a coil spring(front tire) pop out of the compression tool and luckly it hit my hand and missed my face. I couldn't move 2 fingers for a couple days from the blow. :P

Actually, it wasn't wine, it was port. It was a while back when I was in bed with a snapped Achilles’ tendon. When I tried to navigate out of bed past the tray holding the laptop and port...

It was a new laptop, not even a week old. I hobbled to the shop with crutches and helper. They confirmed the motherboard was zapped, and gave me a new laptop. Luckily the warranty covered accidental spillages.

Should have used it more than spilled on it. It's always an accident. :P

I have a Logitech G15 keyboard that is always on from a soda spillage. Better ON that OFF though.

Yeah, it's not as crazy risky as some would have you believe, and I usually take those precautions, anyway. Especially when I'm doing a new build.

See? If you drove a Ford, you wouldn't have these problems.

BTW, my favorite car ever was my late, lamented (stolen), 1967 GTO convertible, which had the distributor in the same place as yours, and used points to boot.

Ouch! My closest close call was the car falling off the jackstands (NOT jack, jackSTANDS) while I was sitting on the ground, perparing to work on the brakes. I pulled my leg out in time, but the drum still landed on my pants leg.

I was only tuning the engine up. The only fords I like is an original GT 40, or a GT 500H.

BTW, my favorite car ever was my late, lamented (stolen), 1967 GTO convertible, which had the distributor in the same place as yours, and used points to boot.

The engine is a '73, so it originally came with points, already changed out thankfully, with a slightly newer pontiac HEI.

Ouch! My closest close call was the car falling off the jackstands (NOT jack, jackSTANDS) while I was sitting on the ground, perparing to work on the brakes. I pulled my leg out in time, but the drum still landed on my pants leg.

Close call. Couple times I thought that would happen.

I could go on. If anybody wants to talk cars, maybe we should start a new thread :P

I don't think it's that bad. But I only have a few games, FF's & such. I won the one I have. :P I think the GBA is the best so far.

Many many years ago, I used to work in submarines. Lots of very confined spaces.
I learnt very quickly to ignore the "move away" reflex as that would normally lead to several more serious injuries.

One doesn't generally think of Hanks doing physical comedy (nothing like, say, Adam Sandler), and I remember that as being pretty funny.
