Hi,
I would like to build a circuit with 555 timer, for testing spark of car ignition coils. I've built the timer circuit, but I have difficulties to choice a proper transistor.
I've attached my circuit. The resistance of ignition coil is approximately 5 Ohms. I'm not sure, but I think that the amperage is about 2-3 A.
Thanks in advance!
