So I purchased my scope a while ago but I'm now going through the basics with it. I was told that after the car starts and runs you should see a net current of 3 to 5 amps, but what I'm seeing is -26 amps. How does -26 amps equate to 3 to 5 amps?
The vehicle is a 2019 nissan sentra and the battery is relatively new. I'm using the Pico2205A 2 channel scope with imported presets from Pico 6 automotive software, and the TA167 current probe.
