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...
Automotive Lab Scope Basics | Understanding the uScope In this video, we walk through the fundamentals of using a lab scope (automotive oscilloscope) — what it does, how it works, and why it’s one of the most powerful diagnostic tools you can own. Using a signal...

In this video, I go in-depth on how the LOADpro Dynamic Test Leads work and how I pair them with the Power Probe for faster circuit testing. I build a simple circuit to demonstrate real-worldish conditions and show why a circuit can appear to have full voltage—but...
Voltage drop testing is one of the most powerful yet misunderstood electrical diagnostic tools in the automotive world. In this video, we break down what voltage drop really is, how it works, and why it’s far more reliable than simple resistance checks. You’ll learn how to test voltage drop across circuits, spot hidden resistance, and diagnose issues like slow cranking, dim lights, or faulty grounds with confidence.
We’ll walk through real-world examples using multimeters, test leads, and shop-proven techniques so you can apply these skills immediately. Whether you’re chasing a parasitic draw or a charging issue, voltage drop testing will give you the answers you need without the guesswork.
📌 Topics Covered:
What voltage drop is and why it happens
Voltage drop vs resistance testing
Testing power and ground sides of a circuit
Real-world voltage drop examples in the shop
Common mistakes to avoid
🔧 This is a must-know skill for technicians working on modern vehicles. Get ready to diagnose smarter, not harder.
