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...
Air Conditioning is a SPECTACULAR Technology, the more you learn, the more interesting it is
In this video, we break down how automotive air conditioning (A/C) systems work. Whether you’re curious about what each component does or trying to understand why your A/C isn’t cooling properly, this is the video for you.
We cover:
– The key components of a standard automotive A/C system
– How refrigerant flows and changes state to remove heat from the cabin
– Common causes of failure like leaks, clogs, and compressor damage
– Why a contaminated condenser must often be replaced—not flushed
– How to diagnose systems with multiple points of failure
– The role of relative humidity in A/C and defrost performance
– Why your A/C runs during defrost mode—even in winter
This is essential knowledge for car owners and aspiring technicians alike. If your vehicle’s air conditioning isn’t working right, understanding the system can save time, money, and frustration.
