Hey CRJ. Mil. was trying to lead you in the right direction. It is not the 12 volts from a battery that would do it. Your coil amplifies the voltage (12volts). As you turn the key on, this allows 12 volts to energize the coil,(and builds up amperage on, I belive the primary side of the coil, like the burner on your electic stove(kinda)), as you turn the key to start your motor, this spins starter which inturn spins the dist., and closes the points which sends this built up (amped up) voltage,(12000-15000 vlots) through your wire, through the spark plug, across to the ground, igniting your fuel.( liquid gas or in your attemps CO.)
Good luck with your EXPEIMENT.

 

CRJ here a page to read up on how a coil produces it's 12000 volts.

Volts dont kill Amps kill, it seems like it takes less than 3 amps to stop the heart, how many amps is your alternator? stock is around 45? the thing is skin is a fairly good insulator for small stuff, I've also heard of people who have hit the wrong line, as in boom trucks going up into high voltage lines 30k+ volts it burned the guy bad!, blew his teeth/joints out etc... You can hear some bad stories working for sparky's. Stun guns go well over 100k volts and wont kill, so it's not the volts that kill in this case :7 :7

Below was Snipped because I understood what was said.

What I meant was I have been JOLTED MANY time with 60hz 110-120vac

My arms go flailing and I Always get Jolted Away.


If it Kills everytime a person touches a live circuit ,I'm either
a Cat or I've got a computer in Heaven with me right now.

Also, It makes me happy to have an electrician here to
correct my mistakes when i make them.

Well, I'm just Shocked at all the responses on the AC vs DC thread---Where is ole' Einstein when Ya need'em----He could straighten us all out on Da Theoritical differences of Da AC versus Da DC---Ya , fd:-X11

 

CRJ,
I've read the rest of these replies and have come to a conclusion:
Hire someone who knows something about what your trying to do. You do not have the basic knowledge needed to achieve your goals.
1. You will need a coil to create the potential needed to force an arc across a spark plug. A car battery has a potential of 12VDC. A coil can create a potential of 40,000 V. By playing with a battery and a spark plug you have only proved that you are no where near achieving what you're trying to do.

-CRJ900 go to this site, it is what I used
< http://www.studz.freeserve.co.uk/creatures/flame.htm >
I have 14 guage wire with a 30 amp inline fuse going to a toggle swich, the wire goes from the other side of the toggle switch to the sparkplug end. The sparkplug is a short lawnmower one and screws into the tailpipe 5" back. The tailpipe is the ground. That's it!

Maybe you need to try a different sparkplug when you do it.
Good Luck -Dan

 

ok, i got all the wiring done, under the truck, inside, now all i need to do is connect the wire to the correct spot on the spark plug. do i connect it to the electrode, or the other end. thakns

 

[updated:LAST EDITED ON 21-Jan-02 AT 06:05&nbsp;PM (EST)]The TOP, where the sparkplug wire would attach.

The sparking end should be in the tailpipe.

If you can't figure out how to attach it.
Find an Old sparkplug wire ,REMOVE the End that attaches to the plug and solder the wire to the clip,and push it on the sparkplug.

so your sayin that it WILL have enough power to make it spark. correct?

 

Forget about a flamethrower,Lets make a stinger out of a coil and a 9-volt battery.

 

what is a stinger

 

Stinger Missle !
Aren't they usually mounted on an F-15 ?
Not F-150's

He's pulling your leg Chris.

I DON'T guarantee a spark.
You'll have to talk to Sparky ,he's in Charge of Sparks around here.
Plus,He's a fireman,so Not only can he can light it But,he can put the Fire Out.
