I've been going through all your playlists. I just made it through every video on temp sensors, and now I'm going through "position sensors" next. I've already been through all the fuel trim vids. Between your channel, Ivan's, Eric O's, Watch Wes work, Mario and diagnose Dan.. I feel like I've been through an automotive college coarse in this past year or two. lol.. I had no idea how much I was in the dark before. I'm in the zone at the moment, and I'm absorbing this stuff like a sponge. Loving it

Awesome ! Excellent teaching techniques ! Loved the question you asked / taught - “ did we have an open in the ignition secondary (wire and spark plug ) … Answer is No because the current pattern at the end of primary (ignition coil) current ramp didn’t have a Big tail (back feeding ringing back into the primary) because it had no where else to go “ ! This tutorial had so much great information . It left no questions / details out ! !! Thanks Paul !

Great video as always. My background is electronics, but thanks to your videos, I can troubleshoot family cars (I hate being a mechanic-broken bolts, impossible to reach parts, burned and cut fingers, etc.). There is a test I use when I have an intermittent electronics problem that appears after a circuit has warmed up. I will spray the suspected (normally the active-high current) component with electronics cleaner, dust cleaner in a can, or anything that will cool the component. This quickly cools the suspected part, and if the problem is heat related, will often cause the component to start working again. On the Audi coil pack, there was a metal heat sink. This heat sink is used to draw excess heat off the three driver transistors since the transistors each flow several amps of current. When the cylinder 1/6 driver coil failed after the engine ran for several minutes, I would have suggested spraying the heat sink with brake cleaner, electronics cleaner, duster in a can, water bottle with a hole in the cap, or anything that would cool the heat sink. If cooling the heat sink restored the operation of the 1/6 cylinder coil, it would have quickly confirmed that the driver was the defective part..

A nice little side experiment that you could do is to put a signal through a wire (or pull from an injector feed or coils, etc.) -- and play with your amp-clamp by half way opening the jaws and also maybe pinch the wires with the jaws, etc.. and just see what the signal does while you try all these different "wrong ways" to connect the amp-clamp. I just think it would be interesting to see how it affects the signal. (plus you could show how flipping the clamp inverts the signal, etc.). It probably wouldn't be it's own video of coarse, but I think it would add some unique content that no one else has done.

Hey Paul, great video and class. Do you ever get students that return after graduation and tell you that they actually get reprimanded at work for testing and not just unloading the parts cannon? I've had a few tell me that over the years, I then point out to them that's why their toolbox has wheels.

20:20 ... To determine which cylinder is which on the waste-spark setup, where you can see both 1 and 6 (for example) but you can't tell which is which, you can simply pull one of the secondary plug wires, and then it would fire on only one of them (I would think). (After the coil started failing again live, that wouldn't work though.) So you would probably just have to sync with one of the other two working coils -- then pull one of those secondary plugs, and finally you would have your sync, and could go from there with your firing order. That's interesting, it's so much more simple on regular coil-overs.
@ScannerDanner
Жыл бұрын
It would affect both (unplugging a wire on 1 side of a waste spark coil) To sync it, the best way is to use a capacitive secondary ignition pickup and clip it on a plug wire. You'll then see a high, low, high, low firing line. High = compression stroke and Low = exhaust stroke and now you'll know when the cylinder being testing is firing. Make sense?
@calholli
Жыл бұрын
@@ScannerDanner Ok, I see. So even then, you'll still see both sides, except for the local pressure change in the cylinder; that compression stroke will give it a high/ low effect. I'll have to remember that.
@ScannerDanner
Жыл бұрын
@calholli yes sir, the cylinder pair that is attached to that coil will alternate high and low firing lines. High on the compression stroke and low on the exhaust stroke. I have some videos showing this technique. But I don't know where offhand. I'd be in my chapter 22 and chapter 1 playlists. I think when I taught relative compression testing in my chapter 1 playlist, I showed how to ID a waste spark system

You can't print directly from it, but there is nothing stopping you from doing screen captures on your PC and then printing individual pages.

ps...testing the coil last video could certainly mislead someone - seemed like the coil was fine when you tested with a test light.

@tombeam from memory, those wires were underneath epoxy, and there would be no room to get an amp clamp in there. Also, an amperage measurement wouldn't have told us any more than what we already knew (current flow was dropping out). Some voltage measurements would have told more of the story as far as open coil or open driver goes. But as you said, it's all one assembly so we were done.
