In this video, I break down how to perform a Relative Compression Test using an oscilloscope. This fast, non-invasive diagnostic method lets you check engine health without removing spark plugs. You’ll learn how to set up the test, connect a current clamp, record the...
Secondary ignition diagnostics are often overlooked in modern vehicles due to coil-on-plug systems—but the waveform still tells a powerful story. In this video, secondary ignition waveforms are captured and analyzed using an oscilloscope to reveal what is actually...
Today we’re rebuilding the rear brake calipers on a DeLorean — a job that solves common issues such as dragging brakes, uneven pad wear, sticking pistons, and handbrake imbalance. The DeLorean’s rear calipers have some unique design quirks, including the integrated...
Learn practical lab-scope workflows you can use today. We reinforce the basics with real-world tests: checking primary ignition current with a low-amp probe, verifying an entire bank of coils via the common power feed, reading fuel-pump current through a fuse-loop...
Everyone’s talking about how bad the automotive industry is right now — low pay, burnout, lack of respect, and technicians leaving the trade. But that’s only half the story. In this video, I talk about what’s really going on in the automotive world — and why it’s not...
