Following the wave of testers for equipment in our car, here I bring you a proven invention of how to make our coil generate the sparks. Without further ado, I show you below:
It is based on the popular relay oscillator, modified a bit by adding a capacitor and a rectifier diode. The materials are the following:
Power supply of 12V and 10A at least.
RL1 - NO and NC double contact relay of Bosh type or for printed circuit.
D1 - Rectifying diode 1N4007
C1 - Polyester capacitor 0.33 uF
C2 - 22uF electrolytic capacitor
Push button normally open.
And of course a coil dry, or in oil.
Do not use electrolytic or tantalum capacitors for the C1 (which goes on the coil) because this type of capacitors are polarized and do not support the high frequency variations of the coil (Do not use it because they heat up and explode hahaha).
Use it with 12V and 10 A power supplies at least. The coil consumes a lot of power. If you use less current, the coil will not have enough power to spark or make one or two sparks and the supply voltage will drop.
Do not mount it in the car, or directly to a battery that is connected to the vehicle. Remember that we are generating high voltage, this passes through the insulation of automotive cables (these insulators only support 1,000 V and the coil produces 30,000 V) very easily, and if a spark jumps to one of them DAMAGE THE CAR COMPUTER u some other electronic element. So VERY CAREFUL WITH THAT.
USE A SPARK PLUG CABLE for the high voltage output of the coil. In my video I use a normal cable for the high voltage terminal of the coil, but it is because I am doing experiments and I know that the spark will not jump through the insulation because I separated it enough from the ground wires.
Be very careful with HIGH TENSION, if you use a pacemaker or any other electrical device that supports you, please do not do this experiment.
Here I show you a video how the tester is made.
Well, that's all for the moment, I hope you like it.

Asked by Edgardo on 04/01/2020No entiendo como cierra el circuitoAnswer: Mmmmm, ¿donde no cierra el circuito Edgardo?
Asked by Edgardo on 04/07/2020Analice el circuito y si esta cerrado pero cuanto es el pulso de duración, deseo hacer uno con pic, y saber como haces con los capacitadores para saber el tiempo. Vi el video y tienes en la regla de prueba un filtro electrolítico. GraciasAnswer: Escribeme por email la duda que tienes a firstname.lastname@example.org. y yo te respondo por allí con más calma.
Asked by Ángel Manuel on 04/09/2020Buenas una pregunta este circuito se puede usar para encender un vehículo con distribuidor a platino en caso que se halla dañado el condensador y nos quedemos varados Answer: Si, es posible sustituir el condensador por este que indico. Tendrá menos potencia, pero podrás arrancar el motor y salir del apuro.
