Injector testing with an Oscilloscope (O-scope)

[Camar068]

Since I put the thermistors on the fan to elliminate current spikes, I thought what about the injectors on the LS? In the end this led me to the video below. You don't have to use the tool he has. As he says in the video and o-scope is fine. I'd like to see that waveform square (no spike), but it's good for troubleshooting to have it. Since an injector is just a solenoid, you could use this testing for other things as well not just injectors.

I have a 20yr old and 40 yr old oscilloscopes for testing and seeing a waveform if it is of help. Been usefull to diagnose timing belt issues and crank/cam position sensors

not that I need one, but someone else might. Are you selling them? I remember when I first went from old school scopes to the new style. Took a few hours to figure out where everything was in the menus.

I doubt anyone would want to buy one of these. Other one is a much smaller hand held fluke(but still 15-20 years old)

but for someone thats never used one, they are super easy. Like I said, no 50 miles of menus to search through....everything has a knob or a button. If it does have a menu....it's minor lol.
