DKGrimm replied to the thread Tests of CDI Ignition Modules.Interesting observations. A lot going on during the 1ms or so duration of a spark. I don't have what it takes to understand the... -
DKGrimm replied to the thread Tests of CDI Ignition Modules.Excellent points. The only reason for the ballast resistor in these tests was to test the coils themselves at different levels of...

DKGrimm replied to the thread Tests of CDI Ignition Modules.Right. I remember you telling me this before, but everything works so well as is I just never bothered to look. I'll do so, but first...

DKGrimm replied to the thread Tests of CDI Ignition Modules.It's taken looooong enough, but I finally got some results to put in front of people. The chart is a summary of results testing the 8...

DKGrimm replied to the thread Tests of CDI Ignition Modules.Sounds like that should be a good combination. Just ordered a 24-71532 for my tests. Looks the same, but if you want me to run one of...

BTW: I can appreciate your final statement. 7. Spend less time writing papers and more time building engines Thanks again for your...

DKGrimm replied to the thread Tests of CDI Ignition Modules.That's in my plan.

DKGrimm replied to the thread Tests of CDI Ignition Modules.You got me. 0.025.

DKGrimm replied to the thread Tests of CDI Ignition Modules.Coil resistance was 1.4 ohms, and I used 2 ohms ballast resistor with a 6 volt sealed cell lead-acid battery. I didn't measure the drop...
-
DKGrimm replied to the thread Tests of CDI Ignition Modules.I know I promised at the beginning of this that I would test various CDI and inductive ignition systems and report the results. It...

DKGrimm replied to the thread Tests of CDI Ignition Modules.I'll do that when I get a chance, Pete. I think you are 100% right about the threat to the Hall sensor. That spike is so energetic...
-
DKGrimm replied to the thread Tests of CDI Ignition Modules.When I said that I was talking about test firing ignition modules into a resistor, as I recall. That load would be very different from...
-
DKGrimm replied to the thread Tests of CDI Ignition Modules.Different sparkplug types, gaps, compression pressure, gas movement (swirl) will all have effects. Besides that, CDI discharges are...
-
And if you really want to get a sense of the spark, you can taste it. A nice spark across the tongue ... let's just say that it will be...

DKGrimm replied to the thread Tests of CDI Ignition Modules.Just using 1/2 watt carbon comp Allen Bradleys, from my 50-year-old stock, except in the voltage divider I ordered carbon films with a...
