A perfect mix of science, camaraderie, entertainment and education.
Keep ‘‘em coming guys.
I for one appreciate the time and effort you put forth.
Hey Joe,
Glad you enjoyed it and thanking for taking the time to reach out and support the channel !
Hey guys ! Tremendous presentation ! Your on camera demeanour and communication and detail loaded instructional techniques are very helpful for the learning uptake I am gaining from you / enjoying !!
Hello,
Thanks for the kind words !
Glad you you like it!

resistor plugs started way before computers to help with radio interference in passenger cars to go along with resistor wire or plug caps
Great point Jim, thanks! Well before I was on this earth ;)

i have been told by coil people that turns ration primary to secondary makes a huge difference but will not really measure resistance levels and some coils have different core materials as in metals
Hey Jim, right, turns ratio, wire diameter, wind quality, core lamination material, and probably more all effect output and longevity. There's a lot that goes into it, thats for sure!

Excellent demonstration. It is much harder to throw a spark at higher pressure, which occurs at low rpm and wide throttle, such as on a freeway on-ramp. My 1996 Plymouth 2.4 L DOHC started missing badly in those conditions, which stopped when I let off the throttle. I reduced the spark gaps from 60 mil to 50 mil, per a TSB for the turbo version of that engine (even higher pressure), and no more misfires. In contrast, sparks easily jump many feet in a high vacuum chamber thru the rarified air, which is easily ionized. BTW, my PCM took a hard hit in an accident, so perhaps a crack in a trace which controls spark or such. Re snake-oil plugs, the old Split-fire ads said they tested normal plugs on a dyno, then Split-fire and measured more engine power. Engine was cold in 1st run, then warmed-up in the Split-fire run.
Men of Science laying down the fax about automotive operational cause and effect. Great information presentation gents! Great that we can find educational pieces like this on youtube now. We've come a long way since the days of paying a small fortune for schooling to be able to learn about topics like this. 👍👨🔧
Thanks a ton for watching! Glad you enjoyed the training :)

Back in the 1960's, OEM's ran non-resistor spark plugs because contact point ign systems put out all of 25K Volts and needed all the help they could get!
My parents 1960 Chevy Bel-Air 283 cu in, 2 speed powerglide used A/C 45S spark plugs. However, I can testify to the noisy AM radio at night when the radio signal was reduced in power due to some government regulation back in the 30's or 40's. Really sucked! Throw in arcing "generator" brushes and "vibrating contact voltage regulators" and.....well you get the picture.
When resistor plugs came along some of those (small) early ign systems would misfire, usually under load foot-to-the-floor driving.
Point bounce wss s whole different problem! Course there was also the "in-line" ign resistor (ballast or like GM, a LONG wire) to lower the primary ign voltage from 12 volts to 6 volts going into the ign coil.
Slowly the resistor plug became better built quality so manufacturers substituted resistor plugs for non resistor plugs in their inventory. Less radio noise at night.
Then came resistor ign wires (distributor cap to spark plug) and their quality became better like the spark plugs. A/C R45S spark plugs and Delco ign wires became the go to on GM vehicles. Almost totally quiet AM radios (all we had till mid to late 60's) at night.
Along came "transistorized" ign systems followed by all the OEM Electronic Ignition Systems" Alternators, better built AM/FM Stereo radios and we thought we were styling!.......till "Computer Controlled Powertrain Management Systems." A whole new ballgame!
And look at vehicles now! Stay with OEM coils and plugs! Especially in Ford F250 5.4L 2 Valve V8 and F350 - 550 6.8L 2 Valve V10's.
Hope you're all doing well.
Hey Mike, thanks for sharing your experiences with the ignition system over the years. Amazing how far cars have come in general, right? All is well here, hope the same for you bud :)
~Mike
Insane! From measuring resistance of an intended open circuit 😜 to remotely lighting the light on a cordless drill....lmao!
I know lots of mechanics that would never believe a spark plug can damage the electronics of a vehicle!
I know, right!? I was just making sure you guys were paying attention LOL! I was such an idiot lol!
~Mike
I REALLY WISH I COULD WATCH YALL'S LIVE FEED, BUT I'M NORMALLY AT WORK WHEN THEY COME ON, YOU GUYS PUSH ALOT OF AESWAVE STUFF, KEEP DOING IT, I LOVE THAT COMPANY, THEY HAVE TOP NOTCH SUPPORT AND THAT TEST TERMINAL KIT FOR 270 BUCKS, I'M ORDERING A 2ND ONE, I WAS EXPERIMENTING AROUND WITH THE PEIZO RESISTOR ON A COM ISSUE, SET IT TO 120 OHMS, NAILED MY PROBLEM OFF THE BAT
Yeah we could not live without our test lead kits!
~Ryan
I would think the best question to ask is an "upgrade" better for my engine and how it is set up. Thanks for a great topic and great video.
gunships in vietnam could sniff vehicles out when they were running under jungle canopy by listening for this noise. i am not an EM specialist but always learning like you all, and enjoy your presentations. youve almost got the the point of developing basic radar 😎
Interesting! Thanks for reaching out!
~Ryan
Missed your live today. Was out in the country here in S.E.Oregon but checked out the vid~Nice going and chat too! Keep Thanks 👍
Hey Bluejay Outpost, thanks bud! Hope you can make it on for the next one :)
~Mike
You didn't mention how when a car was developed, they didn't have the long term testing on the engine to determine if the spark plugs could be upgraded with improvements. They have this with oil on some cars.
Found your resistor plug interesting. I have worked on older farm tractors with six volt coil. The wrong plugs usually create no start or lots of miss fires. Goes back to put the right plug and wires in.
Hey Steven,
I could not agree more!
Thanks for reaching out!
~Ryan
Also learned on antique farm tractors with magnetos , use copper core spark plug wires .
Ya this was awesome. I'd like to see a fuel pump case study of sorts
That's a great idea Rey Rod, we will work on something. Thanks for watching!
~Mike
We like from this job otomotif.super complete.we from Indonesia sir want for study science Otomotif.
Thanks for watching Sidik!
~Mike
Great video. If you don't zero out that AMP probe, none amp readings are correct. May not be huge difference, but it can. Good video either way
Hey Tony, true, the reading may be slightly off...but our goal was comparative testing so it will be off for all the tests the same but consistent.
~Mike
This is great, thanks!....do more videos like this!
Hey Nicholas, thanks man!
~Mike
Awesome guys! Thanks!!
Hey Boomaf16, thanks for watching! Glad you enjoyed the vid!
~Mike
good job
I don't know how you guys have got to the conclusion that the higher pressure requires higher kV. The test showed the oposite, i.e. the higher pressure the lower kV is needed to reach "proper" kV. It seems like the logic failed here.
Hey Gre9i, i'm not sure what your mean? If you watch at this point you can see the KV increase which higher pressure and decrease when I let the pressure out. ua-cam.com/users/liveqqv98MqKlEE?feature=share&t=5165
~Mike
You guys performed a test which didn't confirm that "Performance coils are better", so couple of sentences later you show it as "confirmed". It's lame to me.
I guess that depends on the definition of performance coil to you. We tested what we could test, KV output and burn time in relation to load changes. You can be your own judge of the data and results, of course.

Hey Nick, thanks for joining us live today! Hope you still got to bed at a decent time 😂
~Mike
I like y’all but take us home. You wasted so much time talking without anything being of value to the listeners .
Sorry you feel that way! I though our live audience had a really good time. Did you happen to join live?
~Mike
@@GoTechTraining came and left then came back to watch whole video. You guys are extremely talented and smart but please get to the point the meat of the presentation 👊🏻👊🏻
I hear ya bud, time is precious! Next time we'll try to do a better job to stay on topic...2:20 is a long video! Honestly though, felt like 10 minutes to me 😂
@@GoTechTraining 😂👊🏻 I was born and raised In Wisconsin before joining army and moving to Texas so I get it 😂
Awesome! You missed out on 4 inches of lake effect heavy wet snow today! It was a treat 💩
