Kinda the opposite you might think. You apply power via the + & - terminals, the coil takes on a charge and amplifies the voltage, when power is switched OFF to the coil, the field collapses and dumps its load to ground through the top terminal. A typical 12v coil can put out 30 to 40KV. In order for it to work the power must be repeatedly switched on and off. This guy is using a 555 timer instead of the cars points or electronic ignition switch.
You get me wrong. Your input current that goes into the ignition coil must be alternating current. Pluging an "ac" transformer to a battery does not transform the directed current of the battery to alternating current. Once again, transformers only generate continuous output current if you have alternating input current.
So there are only ac transformers. You would need some kind of oscillator to generate alternating 12V current. But even if you got it to work somehow with 12V input current the output current of the ignition coil would not be harmless!
i have an ignition coil exactly like that. what exactly do i need to make it spark like that? i hook it strait to a car battery battery and it dosnt do anything except get hot. and no spark comes out of the spark plug except a little one when i disconect the battery. how can i make it spark like that?
you need to have alternating current. look up how transformers work on wikipedia. with directed current you only get sparks when you connect or disconnect the input wire.
tried it. it didnt work. i used a 12v ac transformer and all i got was a humming inside the coil. no spark. but i do get a 1 inch spark when killing the ground from a 12v battery
Thats how it works. The field in the coil will only collapse and release its energy when it is powered off. Thats why this guy uses the 555 timer. In a car, the spark plug fires when the ignition circuit opens (off), the circuit closes (on) so the coil can build its charge for the next cylinder to fire. When you open and close the circuit several times per second you get the cool arcing effect.
touch it

when you like, look at my vid "zündspule", 2 ignition coils with 2000w.

any samples of oscillator relating to that? how much frequency is that guy using?

an auto relay and a capacitor work just fine for me most ic's and stuff are to unreliable around high voltage only for very short runs

what sort of switching circut is that? 555timer?

heres somthin else you could do hook that coil up to youre stereo and crank it up, sparks jump to tha music!

dam this is just the thing i have been trying to make, i just need to get one of the coils and need to get a circuit like your one in this.

do NOT plug it into your domestic ac power socket! you might kill yourself!

thats why u use a transistor to give u pulsing dc
niwakun444 4 years ago
DC only for an automotive ignition coil. Then switched on and off rapidly. Thats what the 555 timer is for.
