Hi
We have a Picoscope 4223 and run a business selling electronic ignition systems for classic cars. On some distributors eg Lucas 35D with the module on the side how is it best to test the spark output from the module and hall effect sensor? Also how is it best to check the high tension spark from a cylindrical coil? I appreciate this is probably a basic function for the scope but we could do with some simple tests with waveforms voltage readings etc for test purposes.
Can I assume you are testing the distributors on a vehicle or do you have a “test bed” set-up?
I think a good place to start here would be the Automotive Guided Tests included in the PicoScope software.
Could you take a look at the image below on how to access the automotive menu?
Here you will find the connection details and how to connect your scope along with an example waveform and a technical description of the component under test.
You may have to amend your connection set up depending on vehicle or test bed, and of course the style of distributor.
You can repeat this process for the primary and secondary ignition signals where you can evaluate the switching of the amplifier and the quality of the secondary ignition event.
