Pulse Sensor plus Bonus Footage 

I hired a guy in my shop that worked at Autonerdz before Tom sold it and retired. Cheers 🍻

LOVE THESE DIAGNOSTIC VIDEOS ,,,,,,,,,, ANOTHER BERNIE THOMPSON PLEASE KEEP UP THE GREAT WORKS .

Great video!

Wow it's amazing what you are able to identify with good equipment and wave analysis. Ride the wave. Timing because #1 was only effected and I could picture a bad tooth on the distributor messing that timing or wearing bushings allowing one high spot to touch the pickup. Great analysis and can't wait to see more.

the lean condition is because of the misfire, not a fuel issue because the mixture is not combusted there is a lot of extra left over oxygen and that will register as a lean on the o2 sensor. also my homemade ignition wand is made from a relay coil, and i know that it is polarity sensitive. flip it 180 degreess and the signal will reverse or if its on the edge it could go either way.

Yours videos are amazing, in depth explained

Thank you very much I learning from you a lot specially how to use Pico software math channel/masks for my diagnosis

Like the intro Mr Carter. I see ya.

Looking forward to it Mike

As you said, it could have been the plug, or the coil….the only reason to change both the coil and the plug would be if the Labour cost would have been more than changing the coil, otherwise I believe the plug should have been swapped to see if the misfire moved to another cylinder!

The forklift was very interesting! Essentially the coil dwell time was reversed. Good thing it didn't burn up the coil, I suppose that's what the ballast resistor helps with. While I understood everything you mentioned in the video, you didn't really mention how you got to the conclusion of changing the pickup module. Was it just based on the backfiring, knowing the timing must've changed, and also knowing that nobody messed with the distributor?

Is it possible the coil was absorbing the energy is why the negative spike?

33.40 Isn't it the case that when the ignition is turned on, current flows through the coil depending on the position of the rotor relative to the sensor?

Thanks for sharing. On the forklift, wouldn't the ballast resistor normally be bypassed while cranking for full battery voltage?

I had to go back and watch the Frontier part of the video twice. The secondary portion of that capture takes some getting used to. I know you said the wand is like a giant antenna so I guess that explains the extreme look to the capture. I can see myself going off looking for ghosts until I got comfortable with that. A couple of times in that secondary it looked like there was a ghost kv about 180 degrees from actual fire cycle. Is that just that wand being overly ambitious? In your video Old Sparky I actually felt more comfortable with secondary when you just taped back probe leads to top of coils. Also I noticed Frank Massey said he liked 2 ms or more for burn time. Cars he routinely tests maybe? Thanks Mike, great video as always.

U have some low spikes goin up and down ..is that like a partial misfire or what would cause that
