I am liking the simplicity of using battery voltage to do relative compression. I am going to practice it today with the Vantage Pro. Thank u G!

but is it sensitive enough to see a slight burnt valve/dropping seat?

Why is the voltage higher on the cylinder with the spark plug out?? Wouldn’t it be lower with no compression? It almost looks like an exhaust valve stuck closed

Phil it's based off voltage drop/amperage usage requirement as the starter is turning over the engine. The mechanical resistance changes are what makes the difference in the waveform capture. Hope that helps. Thanks for watching...there are a bunch of other videos on our channel...enjoy we hope they help.If you have not already Subscribed to our tstseminars KZitem channel please do so.

Think you needed to invert the waveform

The Snap ZEUS labscope is set at 200 mV per division or 2 volts per screen and the Sweep/Time is set at 1 second per division or 10 seconds per screen. Other Snap On scopes will have similar voltage and times setups. Thanks for your question and watching. If you have not already subscribed to our tstseminars KZitem channel please do so.

@@gtruglia2720 Is this battery voltage? Why an cylinder not making compression would cause the battery voltage to drop/rise more than the others. It does not make sense what I am seeing on the screen.
