We built the circuit you have shown. We used ignition coil and condansator from the car system. Our relay overheats after 5 seconds or so. What will be the specifications of condansator and relay to use them with car battery ?? Thanks so much.
@offom If the relay is overheating then the most likely cause is the spark is being discharged inside the relay itself. This would be from the spark plug ground being connected to the same ground wire as the relay. On lower voltage coils this is not an issue but for higher voltage coils you need to have all your ground wires grounded to the chassis and not connected to eachother in anyway. In my diagram it shows all the ground wires connecting to eachother. This works only on low voltage.
It sounds like you might have a defective relay or it is hooked up wrong. If you can get sparks with a switch turning it off and on manually and then hook up the relay then it doesnt work then I would say try a different relay. Make sure too that the power is going through the pin that is always connected. Usually 87a is that pin but make sure by using an ohmeter and touch the positive to pin 30 and the negative to 87a and if the reading does nothing then you want to power the coil with pin 87
ok, so we went and tried that and still no luck. it used to buzz for a second then shut off before. it didnt do it consistently though. now it wont buzz at all but we can get a really small spark by clicking the switch on and off.
Depending on how many volts your coil is trying to put out you might have to have the battery, the relay, the coil and the spark plug all grounded seperatley to the vehicle or project your working on and not through negative wires that connect to eachother. If the negative from the spark plug goes to the negative of the relay it will not let a spark generate. Hope this helps!
ive tried this and cannot get it to work. hooked it up like the schematic shown in the video and every variation thereof and still cant get spark with a brand new battery. any help is appreciated.
Could i replace the swith with a cam of an engine for ignition of an engine? just 1 cyl

@SthealthRaider I believe so if I'm not mistaken I think that is how they did the set up on the old school Fords. (or something similar)

Thats a good drawing of the switching relay. Is there any to get a copy?
