If you’ve ever scoped an ignition coil, injector, or solenoid and noticed the voltage spike climbing out of range—this video is for you. This is a practical breakdown of scope attenuators (like 10:1 and 20:1) and how to use them to capture high-voltage automotive signals safely without sacrificing waveform detail.

In this video:

What attenuation actually does (and why it matters)
How 10:1 and 20:1 change what you see on the screen
Which automotive signals commonly need attenuation
Quick rules to choose the right attenuator before you hit “record”
Tips to avoid bad readings (wrong scaling, ground reference issues, noise)
Signals that commonly need attenuation:
injector control signals
Inductive loads with big flyback spikes (relays, PWM solenoids, some injector circuits)

⚠️ Note: Always confirm your scope’s maximum input voltage rating and use the proper leads/probes for the job. Attenuators protect equipment—and keep captures accurate.
