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...
When Your Dash Lights Up, Here’s What It Actually Means – Most of the Time…
Seeing several warning lights on your dash at the same time? Don’t panic — it’s often not as catastrophic as it looks. In fact, most of the time, this is by design. Manufacturers know drivers often ignore a single check engine light, so modern vehicles are programmed to trigger multiple warnings at once to grab your attention and encourage you to stop and get the vehicle checked out.
In this video, we break down:
Why multiple lights may come on together — and why it’s often intentional
How a simple issue like a loose gas cap or weak battery can cause a chain reaction
Specific examples of makes and models that we know do this in an extreme way
What’s normal (like a startup bulb check) vs. what’s serious
You’ll also learn how to tell when it’s safe to keep driving and when to call a tow truck.
Whether it’s your check engine, ABS, traction control, or all three — this video will help you make sense of it and know what to do next.
