Just be thankful your heartbeat didn't stop.

I think it did for a little bit. I feel a bit funny now.
Its not really the current that kills its the frequency i think. I deal with high voltage stuff all day at work, so why the fook did i touch it.....?

frequency ? ........
i hope your better at your job than your statement sugests if i said something like that at work i would be fired and marched straight off the premesis.
http://en.wikipedia.org/wiki/Electric_shock said:A low-voltage (110 to 220 V), 50 or 60-Hz AC current travelling through the chest for a fraction of a second may induce ventricular fibrillation at currents as low as 60mA. With DC, 300 to 500 mA is required. If the current has a direct pathway to the heart (e.g., via a cardiac catheter or other kind of electrode), a much lower current of less than 1 mA, (AC or DC) can cause fibrillation. Fibrillations are usually lethal because all the heart muscle cells move independently. Above 200mA, muscle contractions are so strong that the heart muscles cannot move at all.
My f**king chest is killing.....:dapprove:
Was trying to see if leads were loose.All i did was touch the rubber casing then wallop!!!!!
Is this normal....lol.:S
you are obviously missing your V=IxR
you dont want to know what i do for a living
yeh....dohI thought you only got a shock if your touching the bodywork at the same time?
current's the killer.
i think legoland may have got a bit mixed up with AC and DC, still both carry current, one on a frequency the other one directly.
i think..........from my uni days!
I've never had a pisser off a car *touches wood*
It's the current that f**ks you. Doesn't take much either. Hence RCD's being 30mA in your house (or should be - very few people have them lol)
Sparkie? I aint a f**king house basher! (not that there's anything wrong with house bashers - just couldn't be further away from what I do lol)
I figured it ought to come from someone qualified to say it
I'm an Engineering Technician thank you very much.:rasp: :rasp:
Fitters... I s**t em I've been certified as multiskilled by my company for removal of a dual seat tuchenagen valve and putting a toy town gear box back together. LOL Makes me laugh. Extra 2.5k a year though!
Frequency does effet the way your body is shocked.... but ultimately it's current passing through you that determines whether or not your heart stops or you get severely burnt up. Ouch.

Flol @ Engineering Technician.
We are all that mate, oh hang on My correct title is Steam, Refrigeration and water services Technician lol.

PMSL. I wouldn't mind that. Mines's shocking.

LOL
Anyway. At least LegoHead hasn't suffered any ill iffects. Whether it was the current or the frequency () that got him an electric shock is never a nice thing!
You guys have got nothing on me..
Lego man..
Dont worry about it, you shall learn and do it again.
Basically in short..
The coil pack is a capacitor, it receives a LT (low tension) input from the car, maybe 5~12v from the ecu. From here, the coil pack builds up the voltage too about 50,000volts, where a contact arcs over when a set voltage is reached and pushed the output (50,000volts) to the spark plug via the HT (high tension lead).
Therefore if you turn the engine off, or disconnect the system. It is best to let the system discharge for about 3~4 mins otherwise you could be risking letting yourself discharge that capacitor.
The coil pack has 2 sides, LT and HT..
You had a shock from the HT side as you were the shortest path to earth, as in normal operation its through the plug across the gap to earth.
A lesson learnt..
technically, the frequency of an ac voltage waveform does make a difference of the effects it has on the body. IIRC 50Hz is THE most dangerous frequency for AC supply (todo with heart / brainwave natural frequencies) and a slight variation of this reduces the chance of death via shock significantly.
