LS2 Ignition Coil Tester / D585

This video will describe how to test LSx coils by triggering the coil and creating a spark that can be measured. A trigger circuit will be covered that can be built with a 555 Timer on Veroboard.

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.

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

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.

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

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.
