LS2 Ignition Coil Tester / D585 

I never miss one of your videos. They are always very practical and interesting. Thanks.

Fascinating project ! Interestingly, 3.5 milliseconds seems like such a long time, when fractions of microseconds can be measured with micro-controllers.

Well done, I'm keen to give it a go

Nice looking project! Thanks!

Another interesting project Ken and a great use for the ubiquitous 555. The arc length-to-voltage demonstration reminded me of the the old TV EHT probes that used to work on this principle.

Thanks in advance, we need to dissect the injection coil and touch the industry

Very interesting Ken. You do great videos.

Thank you for posting! Very interesting. I will try to adapt your circuit to a bench test bed for old dwell/tach meters. I have 6 cylinder vintage vehicles with 6, 8 and 12 volt systems and a box full of old test meters. I'd like to use this circuit to see which meters are a suitable fit for each voltage system. What dwell angle is your 3.5 ms equivalent to?

Why not just use a dmm to test these coils.

👍👍👍👍👍
